I've had the 650W version since Oct 2016. It's powering an i7-6700K with a GTX 1080. Absolutely zero issues so far. It's quiet and efficient and solid. Can't recommend it enough. If the price tag fits within budget....
My only gripe is the motherboard power cable. It's a split cable and kind of annoying to deal with. But then you only need to mess with it once per motherboard upgrade so really it's a very minor issue.
Just out of curiosity, why didn't you go for the 750W if the price difference is just $5? Is it for efficiency reasons (less efficient than the 650W at your system's typical load)?
Low load efficiency was the reason I purchased a 350 Watt Seasonic SSR-350ST from newegg a few days ago instead of the SS-520GB or the SS-620GB @ B&H Photo for the same price when they were on sale last week
I wish you would cover power supply replacements for Monitors sometime
Had a standard 19 Volt LG power supply crap out last month and the only replacements I could find are basically CRAP
A T-Power replacement actually MELTED within 3 days and became non-functional before it had a chance to burn the house down
Other online stores for Monitor power supplies are complete scams selling more Chinese CRAP instead of the original equipment listed in their ads
I ended up using a VERY Old 120 Watt - 15 Volt Athena Laptop power supply with the T-Power Plug spliced to it's output
It works fine on 19 Volt LG's and cost about $30 around 10 years ago
I was a bit worried about EBay replacements for LG supplies but may need to try that route next time unless anyone knows where to buy "QUALITY" supplies with output current rated "above" what the stock LG's put out
Computer Power supplies are well covered at all the tech sites... Monitor Supplies are never covered Why is that?
When I was overclocking a Korean IPS I bought a high power brick designed for medical applications on an online industrial parts catalog. Cost a bit, but works perfectly (after swapping the output connector)
@close - Two reasons. 1) At the time the 750W was more than a $5 difference. I purchased mine >6 months ago. 2) I try to size my PSUs to the load so they hit the peak of efficiency for the majority of my tasks. Granted, the difference is minimal for this particular 80Plus Titanium PSU, but old habits die hard.
Wow. I've read a lot of your psu reviews, and I don't think you've used the words 'insanely good', 'unbelievable' - and of course 'mythical'. Even though the price is high, getting one of these and keeping it through upgrades for over a decade is probably a better deal than a lower end psu you have to replace several times
It's pretty disheartening to think that they wont be modernizing either the cable layout/connectors or any other aspect of the PSU. It would be great if they could make things smaller/more direct. With the move to a single 12v rail, you would think they would move to single hot/ground per CPU/GPU connector. They have changed the insides a bit. Why there isnt some sort of data/status connector between PSU and MB... At very least to communicate PSU temps, but to add voltage,.. info, instead of all those sense cables.
Moving to single wire bundles wouldn't gain you anything, and in fact loses you things. The reason there's 2 or 3 wires in those pcie bundles is current capability -- both for the connector and for the wires. So you still need the same amopunt of copper (actually, slightly more) to do that, if you move to having single wires instead of doubled. but those wires are going to be stiffer and more expensive. In other words, that's a bad idea.
And re Status connectors -- while Seasonic could unilaterally add something custom, how many motherboard companies do you think would put a matching connector on? Also, the only thing that even *can* be monitored inside a PSU is the fan speed. That's why they occasionally had a fan speed wire coming out, which you can put on a motherboard fan connector. Only nobody ever used that function.
There just isn't any digital logic inside a PSU to communicate with. Motherboards can monitor voltages just fine on their own through the ATX connector.
(also, changing the connector type requires changing both the power supply *and* the GPU, which is awful.)
If Seasonic wanted to make a status connector to the mobo, they could just terminate it in a plug for a USB2 header like the one company currently making them is.
No, PS internals have gotten a lot better. The cabling/connectors have not kept up.
As i went through the effort of having my latest PC have all custom power cables(not for looks), i researched quite a bit and than having done it(not just read/talk), the connectors and cabling can stand to get modernized quite a bit.
These connectors were designed for a time when the vision and landscape for PCs was very different. Everyone was going to have their own. Like how each house had multiple TVs. TV numbers have died off as the landscape has changed. So have PCs. The internals and toolings should match the new PC user. Grandma/pa/person who doesnt need it: they use smartphone/tablet/laptop. It's very much a power user.
status??? how about temperature, so you could have system fans do the heavy lifting? or give the OS a chance to do something about a bad situation?
OK, I get adding "status" output (even though it's a pretty dry and useless data stream to stare at if you have a PSU that's so rock solid it can run for a decade straight without twitching). But how exactly do you propose they "modernize" the cabling and connectors? Not even considering that changing connectors to a new standard for no good reason (other than to piss all over existing standards that work fine) seems silly, there's other issues too. Someone else mentioned it already but it bears repeating: if you reduce the number of wires, but you still need to carry the same amount of current, you MUST move to heavier gauge wires. That means thick, less flexible cabling that people would hate. Does that sound modern? What's the benefit? Are you a better engineer just waiting to show off your superior designs?
I have the 850w but I'm experiencing gpu coil whine..
I had read that this kind of coil whine is not dangerous for the devices , whether it is the power supply or the graphics card, could you confirm it to me.
What is weird is that the noise occurs at + 30FPS +, i've limited FPS to find out it does not occurs only at high fps as i was used to with coil whining GPU... I try to play with the sliders of MSI afterburner and I can hear that the sound changes .
After that I only hear it if the fans are at their lowest and the panel is open so if it is certain that it cannot harm my configuration, it is not very serious but I would like to be sure. However I would like to understand because the problem arises with:
2 different graphics cards (EVGA FTW3 2080ti and Asus Strix 2080ti Oc that someone gave me for test purposes). The two cards do not make this noise in another config 2 power supplies of the same model (Seasonic Ultra Prime titanium 850w) 2 motherboards of the same model. Asus Maximus Hero XI Cstate on and off Mod cable cables or original cable
it's driving me crazy mostly because I don't understand WHY but I'm pretty sure it's psu related..
I have to say, I'm absolutely blown away by the quality of the power coming out of those units. The ripple figures are insane (in a good way!). Considering that I'm looking for a new PSU - this may be 'the one' even at a $160-180 price tag.
It is nice to know that if you pay an extra $70 for a power supply, namely a whopping $4-10 a year in electricity savings! Boy, high efficiency sure does pay for itself dont it?
High-efficiency is only one perk. The superlative ripple, transient response, etc of these Seasonic units means you're providing your high-end components with quality power. This means longer life, better stability, and greater over-clocking headroom.
A solid PSU is the cornerstone of a proper build done right.
The price difference would pay for itself in 7 years and considering that this unit has a 12 year warranty, the difference certainly would pay for itself. There are also additional factors to consider if say electrical prices increase. Return on investment would occur sooner under such a scenario.
The real challenge is if motherboards continue to adhere to the ATX power spec for another decade. Using this power supply down the road could be challenge in that context. To these models credit, it is fully modular so if an ATX replacement were to arrive without adding any additional voltages (i.e. using only 3.3V, 5V and 12V), then an adapter cable could be created.
These are appear to be excellent units worth the price premium they command.
It's not just the whole ATX standard, but all the stuff around it that would make me leery of planning on more than a half dozenish years from a PSU for deciding if the premium is worth it. We've been ATX for the last 20ish years during which time we've gone from 3.3/5V centric to mix low/high voltage centric, to 12V centric designs. Extra CPU power has gone from 6 pin 3.3/5V to a 4pin 12v to 8 pin 12v. Peripheral connectors have gradually gone from Molex to Sata. GPU power has gone from a 4pin Molex to 6pin to 8 pin. While an older PSU may work with suitable adapters (only the CPU connectors and 3.3/5 vs 12v centric designs are breakers); doing so becomes progressively more of a kludge.
Yeah, but there's no reason whatsoever to think that we're going to move away from 12V centric any time soon, or ever. It's possible that we're going to drop legacy rails such as 3.3 and 5 like we did -5/-12 (already mostly gone), but I don't see us moving from 12V centric to 24V centric or 48V centric, even if that would give further efficiency advantages, and I don't think the 12-to-1.1V DC-DC converters are meaningfully less efficient than 24 or 48 to 1.1V -- so the possible gains are mostly in using less copper for the current carrying capacity. I don't see that as enough of a gain to overcome the inertia of the whole industry.
Plus, the desktop PC industry is dying anyway, and when you're slowly dying is not usually the time to reinvent whole parts unless that can prevent the slowly dying.
A friend upgraded their qx6600 systen 3-4 years ago, and I got the guts (MB, CPU, RAM) of the old system. Another friend was retiring a Micron Millennia PIII system from ~1997. I was planning to use the qx6600 guts in the Micron Millennia case, but as I was looking at it, I would have needed a massive number of power adapters to be able to plug things in. I said fine, so what?, but then I looked at the 12V output on the PSU. I was short amps. It wasn't even worth buying the adapters to try it. I threw away the guts of the Micron Millennia including the PSU. In short it's going to be a rare 90's power supply that has enough 12V amps that it would be usable today even with adapters.
The Micron Millennia case though, is very well designed. The fans clip in and swing out of the way on hinges, there's fans where they're needed. The drive arrangement is nice, the PSU is mounted on a hinge to make cable routing easier. There's plenty of drive bays. All the proper standoffs are there for a large motherboard. It's a really good case especially being from 1997. The only two issues were the power button quit working about 2 years ago, so I have a power button cable run between the side panel and the case, and the other issue was the standoffs for the motherboard are insanely long. I had to special order those so that I had enough to support my large motherboard.
I run a number of personal systems 24/7 doing various tasks for me and while idle performing computations for WorldCommunityGrid.org (curing cancer and such) My main system was powered by a PSU from ~2000. It was rated at 250 and I was pulling somewhere between an estimated 330 and 390 watts 24/7. It felt like it was spitting fire from the exhaust. To the credit of the Chinese no brand power supply it lasted for 16 months running 24/7. To replace that I bought an Enermax Platimax 80+platinum power supply, and about the same time I bought another 80+ platinum power supply for the qx6600. The energy savings have been noticeable with both, and they're cooler and quieter. Sorry, I don't have solid numbers to share,but I'm certain I've saved a large portion of their costs. The frustrating part is seeing reviews for 80+titanium power supplies at less than half the cost of some of the power supplies I bought.
I'm really glad 80+titanium power supplies are happening, but why now? What changed to make these possible? Couldn't these have been made back in 2000? Why weren't they? Or are things honestly that much better manufactured today?
I have often felt the same way, and I think it is just that now that prices have fallen so much, branding matters more. Also, the entire clear PC window case thing has people caring about aesthetics more.
That said, modern PSU's are truly better than they have ever been. I am rocking and loving a Seasonic, and it is amazing just how good these new PSU's are. Your Platimax will likely last until the standards change.
For a power supply that has a 12 year warranty, that saving is pretty good, it'll last that long. It usually costs me a lot more than that, I get all of my power supply cables individually sleeved.
Let's hope their eventual redesign won't be as bad as the X-series redesign was. I've had two fail (1 blew on first power-on, the other after half a year) while my original X-400 is still happy as ever after running out of its warranty, regularly driving ~400W of components.
In contrast, my 2nd gen X-750 has run like a champ for the last 4 years. My system also doesn't pull more than 450W so I keep the PSU power draw in the sweet spot which is why I got the 750W instead of the 650W.
I had the X-650, bought when it first came out in 2010 and used it in a computer that i rarely turned off until Jan of 2017 when I sold it. I payed $120 for mine at the time. But the competition is stiff and people are price sensitive, they do not want to hear why they need a PSU that expensive. I can imagine the company had to find ways to reduce costs on the X series, resulting in failures.
I believe the PRIME Titanium series offered here represents the best the company can offer and we already know the company can produce a quality product, and quality costs money. The PRIME Titanium, at $160 shipped represents what the X Series was when it first came out.
They certainly appear to be awesome power supplies. I just wish someone would focus on the low power market for ATX power supplies. I realize as a heavy user, my rigs are rather lightweight, mostly because I have heavy use, but not rigorous gaming. My Desktop running a GTX750 and i5-3570@4GHz sips 122w with an Antec Earthwatts PSU under both gaming and Handbrake loads. I could probably push it up over 140 or 150w with something like furmark, but that doesn't represent a realistic load case. That is with a couple of HDDs, an SSD, 16GB (4x4) GB or DDR3 1866. No, not the most ridiculous system ever, but even if I slapped in something like a 1060 or whatever it is doubtful I'd push the system beyond about 250w.
My server is running a Celeron G1610, an SSD and a couple of HDDs with 8GB of DDR3 (2x4GB) and an Intel ET GbE adapter. It sips 19w at idle with the drives spun down, 31w streaming to my AppleTV with the HDDs spun up and about 50w under max CPU load all with a Seasonic SSR-360GP.
Realistically most gamers probably don't even need something with more than about 400w of delivered power and most mainstream users/systems are looking at <200w peak. For some of these lightweight builds it would be really, really nice to see some high efficiency systems in ATX form factors that were targeted more at 100-200w range.
Even my Seasonic SSR-360gp as nice as it is, only manages about 75% efficiency at 19w and its power factor is about .72-.74
While I agree 100%, it would be really nice to see some extremely high quality, lower wattage PSU, from my understanding it's a lot easier for them to hit higher efficiency ratings with higher power PSUs. However, I'd sacrifice the titanium efficiency for a lower power supply with the same top notch components throughout. I'd even pay good money for it. Sadly anything around 400W-500W is generally more focused on price than quality though some of the OEMs like Seasonic do make better ones in that range than you can find in your other brands.
Yeah, it's the same thing down in the mITX space. My i7 + 1060 ITX is only pulling ~120ish watts while gaming. Something in the lower wattage range, and preferably in a SFX form factor, would be well suited. Other companies make them, but not in Seasonic's quality range.
If I remember correctly, a Seasonic rep used to post comments on reviews of their products here, and he stated that they couldn't source 80+ Gold quality capacitors that would fit in SFX PSUs. I wonder if that's changed in the last few years.
I want to say that Enermax and Seasonic have high-end 400W units that are platinum rated. They are not cheap, but they are really nice. I want to say I saw a review of them compared, but I forgot where. Many of the high-end low power systems are fanless.
I understand your point of view, as I also appreciate fanless. However, just keep in mind that very few builds are going to stress these power supplies to a point where they'll even turn the fan on. I have a Seasonic 650W from years ago and I am not sure the fan has ever even spun up.
Keep in mind the 600W fanless is probably just the 1000W model, minus the fan. Or maybe one of the others, but either way, it'll just literally be one of the other models minus the fan. *Possibly* with larger heatsinks, but I wouldn't count on it.
Higher rated PSUs necessarily have reduced low-load efficiency, even PSU's as good as these. So it's highly unlikely the 600W fanless is a 1000W model minus the fan; that would significantly reduce the efficiency at low loads, which, given their aim with these models, I seriously doubt is a tradeoff seasonic would have been willing to make.
Seasonic makes a 500W fanless unit, but it is simply a 1350W unit without the fan and some big heat sinks. Enermax also makes robust fanless units up to 500W, but they are basically the same high-wattage unit with the fan removed and larger heat sinks. You might as well buy a 1200W or 1350W PSU that does not spin up until it hits a certain wattage (usually 300W to 400W).
Not that i wouldnt have minded getting one, but read the wiki on 80 Plus. Gold is plenty fine. Im very happy with my SFX Corsair SF450 PS that has never turned on its fan(GPU is GTX 1060 6GB). Never seemed hot to touch. A good GOLD PS seems to not generate enough waste as heat to matter. Its almost one year since using it in new PC.
Of course its positioned nicely, big vent up, for convection, per fine print, and its right under a vent, SilverStone SG13B case. One 140mm fan upfront is only system fan. Its does not get noisy level RPMs either. (just get silverstone atx to sfx adapter that is vented, centers PS, dont get corsair one. last i checked a year ago...)
Oh wow, the reviews are in and our product is exceptional. Now let's see if we can improve these margins! How would we go about that? Let's see... maybe we can find a manufacturer who can do it for less.
Great review as always. Having a good PSU is essential for the longevity of the components. I mean, what's the point of the 16-phase VRM design of your MB if you are feeding it crap power? And how far can you overclock your GPU if your 12V line is full of ripple and noise? The efficiency is the cherry on top.
Being a very satisfied owner of a Seasonic Platinum 850W, the only reason I'm not buying the Prime is because the Platinum is already extremely good and it's powering my home server 24/7 for years now.
Platinum only has guarantee for 20% and above, for a 850W PS at 20% load that is 170 Watts. Platinum guarantees 90% efficiency at 20% load so 170Watt load from PC would draw 189W at wall.
Titanium adds a 10% load guarantee threshold of 90% efficiency, so a 850W PS need a 85W(95W at wall) load to 170W(185W at wall, titanium gives 92% at 20%) load.
you aren't really a tech guy are you? Don't fix whats not broken. Why change power connectors as they fulfill their purpose just good? What would be benefit of such more compact redesign? That they look better? lol give me a break And if it is disgrace for your sight to look at them, you only need to do it once when you build PC. Hope you can manage.
Go and buy yourself new phone or fancy toy to satisfy your thirst for modernity...geez
Funny you would say that since the 80's mainboard connectors (AT - 2x6pin Molex) were smaller then our big modern ones (ATX). Of course I would not want to be constrained to AT power requirements.
Well-written review as usual, offering a good balance between technical detail and readability. I have however noticed that you use the term "primary conversion bridge" in your PSU reviews. I believe you're referring to the component which converts AC to DC; if so, it's properly called a "bridge converter". That aside, do keep up the good work!
Actually in many if not most English-speaking countries. Countries aside - it's also used by the semiconductor industry, including manufacturers themselves. For just a few examples:-
The only thing I'm interested in from this series is the minimum wattage option, the 600W fanless. And also hope that seasonic will offer lower wattage also in this product line. (like 300-500W range) I'll never use more than one GPU so have no use for PSUs more than 500-600W, even overclocked.
I have the 750 watt version and it's a work of art. Either than fan has never spun up or i cant hear it. Even with a 5.0ghz overclock 7700k cooled with a nh d15s and thermal grizzly liquid metal with the ultra low speed adapters for the fans. Inside a fractal define r5 with 2x 140mm venturi HF intake fans and 1x 140mm fractal exhaust that comes with it. controlled with asus fanxpert. System is dead quiet and powers everythng like a boss. paired with an rx 480 overclocked to the max since i have a free sync monitor. im happy with 144hz 1920x1080 gaming on a curved 27" acer predator. Thank you seasonic for making the best PSU ever made.
I have a crucial mx 300 2TB for my storage and im waiting for 256GB optane SSD's to switch that over the boot drive and most used apps. I am not bothering with the caching version.
no optical drive all drive cages removed for max airflow as well. I am the most proud of the build if u cant tell it's in my bedroom and i cant even hear it when i sleep. I'm so ecstatic.
No, though I've come to the realization that you have to treat dB measurements as an internal metric for each article/site and not an universal truth.
Variations due to measuring methodology, equipment and ambient sound level means dB measurements don't compare well across different reviewers/sites.
Personally I prefer always-on equipment such as case and CPU fans to idle <20 dB and load noise, including GPUs, <30-35 dB so I reckon I'm in a similar position. Some reviewers, a surprising number even, have ambient sound levels higher than I'd tolerate even a fully loaded computer to make.
More than that dB measurements fail to pick up sound characteristics. A great fan/cooler can be tolerable at higher dB levels because the only real sound tends to be from moving air, a soft "whoosh" if you will. The bad ones add ticking or grinding, for example I find the default Radeon fans to be completely intolerable at any load level. And even fanless equipment may be saddled with electrical noise that cut right through the case and ambient sound.
In the end you really have to listen yourself to make a judgment and if that's not an option rely on a comparison to a unit you've heard yourself that's been tested by the same reviewer/under the same conditions.
u wont be disappointed with a 750 watt seasonic prime. The fans dont even turn on until u hit 375 watts of power draw. Which basically means even maxing out ur cpu isnt enough to turn them on. You have to play a game and most games utilize like on averahe 80% of ur cpu and yea the fan on the psu is dead silent when it does spin. Concentrate and getting a quiet GPU. Get a triple slot with GPU with a HUGE heatsink and adjust the fan profile till right before you hear it. The highe heatsink makes yup for the large speed. I really like the triple slot gpu's with 3x 100mm FDB fans plus nh d15s noctual cooler using liquid metal paste and the awesome titanium rated seasonic psu. With 11 blade fractacl venturi high flow fans with thge drave cages inside removed. this way you need no static pressure so even on low speeds the air pushes deep into the case and since its 2x 140mm inttake 1 140mm GP14 fractacl exhaust yu get positive pressure meaning you only have to clean the case once every 2-3 years as only microscopic particloes get in. You can run the fasn all at the lowest speed before you hear it even with good overclocks. I sleep right next to the bed thats how quiet it. Seriously I will facetime you thru the build for 45 buvks an hour. And teach you all the tricks to deaden every vibration while keeping all ur components in the 70C's or less
its the best build in the world if u want silence and still a lot of power, yes no9t the max power but if you all u care about is gaming at 1080 with 144hz which imo is better then 2560x1440 and 60hz by a far as well a 4k at 30-60hz by far
I will give you one of my secrets spraying the sound deadening dynamat on every piece of bare metal you can see. and not using any spinning hard disks in the build to show you I am for real. We can face time or skype and I will guide you to killing every vibration in ur machine a baby could sleepp next to it. I've already had 1 taker it only took 1 hour so im raising the fee to 70 an hour as he got a bargain for 45 dollars of bitcoins. You want a quiet machine im ur man this is my passion.
From the conclusion page: "...they are not using any of the latest “leading” topologies or technologies" What topologies and technologies? Who is using them? Perhaps there's hope for an 80+ standard that goes beyond even Titanium?

I've had the 650W version since Oct 2016. It's powering an i7-6700K with a GTX 1080. Absolutely zero issues so far. It's quiet and efficient and solid. Can't recommend it enough. If the price tag fits within budget....My only gripe is the motherboard power cable. It's a split cable and kind of annoying to deal with. But then you only need to mess with it once per motherboard upgrade so really it's a very minor issue.

It's pretty disheartening to think that they wont be modernizing either the cable layout/connectors or any other aspect of the PSU. It would be great if they could make things smaller/more direct. With the move to a single 12v rail, you would think they would move to single hot/ground per CPU/GPU connector. They have changed the insides a bit. Why there isnt some sort of data/status connector between PSU and MB... At very least to communicate PSU temps, but to add voltage,.. info, instead of all those sense cables.JasperJanssen - Saturday, April 8, 2017 - link
Moving to single wire bundles wouldn't gain you anything, and in fact loses you things. The reason there's 2 or 3 wires in those pcie bundles is current capability -- both for the connector and for the wires. So you still need the same amopunt of copper (actually, slightly more) to do that, if you move to having single wires instead of doubled. but those wires are going to be stiffer and more expensive. In other words, that's a bad idea.And re Status connectors -- while Seasonic could unilaterally add something custom, how many motherboard companies do you think would put a matching connector on? Also, the only thing that even *can* be monitored inside a PSU is the fan speed. That's why they occasionally had a fan speed wire coming out, which you can put on a motherboard fan connector. Only nobody ever used that function.
There just isn't any digital logic inside a PSU to communicate with. Motherboards can monitor voltages just fine on their own through the ATX connector.
(also, changing the connector type requires changing both the power supply *and* the GPU, which is awful.)

No, PS internals have gotten a lot better. The cabling/connectors have not kept up.As i went through the effort of having my latest PC have all custom power cables(not for looks), i researched quite a bit and than having done it(not just read/talk), the connectors and cabling can stand to get modernized quite a bit.
These connectors were designed for a time when the vision and landscape for PCs was very different. Everyone was going to have their own. Like how each house had multiple TVs. TV numbers have died off as the landscape has changed. So have PCs. The internals and toolings should match the new PC user. Grandma/pa/person who doesnt need it: they use smartphone/tablet/laptop. It's very much a power user.
status??? how about temperature, so you could have system fans do the heavy lifting? or give the OS a chance to do something about a bad situation?
Alexvrb - Tuesday, April 11, 2017 - link
OK, I get adding "status" output (even though it's a pretty dry and useless data stream to stare at if you have a PSU that's so rock solid it can run for a decade straight without twitching). But how exactly do you propose they "modernize" the cabling and connectors? Not even considering that changing connectors to a new standard for no good reason (other than to piss all over existing standards that work fine) seems silly, there's other issues too. Someone else mentioned it already but it bears repeating: if you reduce the number of wires, but you still need to carry the same amount of current, you MUST move to heavier gauge wires. That means thick, less flexible cabling that people would hate. Does that sound modern? What's the benefit? Are you a better engineer just waiting to show off your superior designs?Asryan - Wednesday, August 19, 2020 - link
I have the 850w but I'm experiencing gpu coil whine..I had read that this kind of coil whine is not dangerous for the devices , whether it is the power supply or the graphics card, could you confirm it to me.
What is weird is that the noise occurs at + 30FPS +, i've limited FPS to find out it does not occurs only at high fps as i was used to with coil whining GPU... I try to play with the sliders of MSI afterburner and I can hear that the sound changes .
After that I only hear it if the fans are at their lowest and the panel is open so if it is certain that it cannot harm my configuration, it is not very serious but I would like to be sure.
However I would like to understand because the problem arises with:
2 different graphics cards (EVGA FTW3 2080ti and Asus Strix 2080ti Oc that someone gave me for test purposes). The two cards do not make this noise in another config
2 power supplies of the same model (Seasonic Ultra Prime titanium 850w)
2 motherboards of the same model. Asus Maximus Hero XI
Cstate on and off
Mod cable cables or original cable
it's driving me crazy mostly because I don't understand WHY but I'm pretty sure it's psu related..

I have to say, I'm absolutely blown away by the quality of the power coming out of those units. The ripple figures are insane (in a good way!). Considering that I'm looking for a new PSU - this may be 'the one' even at a $160-180 price tag.helvete - Friday, June 16, 2017 - link

Written like a true Republican.GhostOfAnand - Friday, April 7, 2017 - link
High-efficiency is only one perk. The superlative ripple, transient response, etc of these Seasonic units means you're providing your high-end components with quality power. This means longer life, better stability, and greater over-clocking headroom.A solid PSU is the cornerstone of a proper build done right.

The price difference would pay for itself in 7 years and considering that this unit has a 12 year warranty, the difference certainly would pay for itself. There are also additional factors to consider if say electrical prices increase. Return on investment would occur sooner under such a scenario.The real challenge is if motherboards continue to adhere to the ATX power spec for another decade. Using this power supply down the road could be challenge in that context. To these models credit, it is fully modular so if an ATX replacement were to arrive without adding any additional voltages (i.e. using only 3.3V, 5V and 12V), then an adapter cable could be created.
These are appear to be excellent units worth the price premium they command.
DanNeely - Friday, April 7, 2017 - link
It's not just the whole ATX standard, but all the stuff around it that would make me leery of planning on more than a half dozenish years from a PSU for deciding if the premium is worth it. We've been ATX for the last 20ish years during which time we've gone from 3.3/5V centric to mix low/high voltage centric, to 12V centric designs. Extra CPU power has gone from 6 pin 3.3/5V to a 4pin 12v to 8 pin 12v. Peripheral connectors have gradually gone from Molex to Sata. GPU power has gone from a 4pin Molex to 6pin to 8 pin. While an older PSU may work with suitable adapters (only the CPU connectors and 3.3/5 vs 12v centric designs are breakers); doing so becomes progressively more of a kludge.JasperJanssen - Saturday, April 8, 2017 - link
Yeah, but there's no reason whatsoever to think that we're going to move away from 12V centric any time soon, or ever. It's possible that we're going to drop legacy rails such as 3.3 and 5 like we did -5/-12 (already mostly gone), but I don't see us moving from 12V centric to 24V centric or 48V centric, even if that would give further efficiency advantages, and I don't think the 12-to-1.1V DC-DC converters are meaningfully less efficient than 24 or 48 to 1.1V -- so the possible gains are mostly in using less copper for the current carrying capacity. I don't see that as enough of a gain to overcome the inertia of the whole industry.Plus, the desktop PC industry is dying anyway, and when you're slowly dying is not usually the time to reinvent whole parts unless that can prevent the slowly dying.

A friend upgraded their qx6600 systen 3-4 years ago, and I got the guts (MB, CPU, RAM) of the old system. Another friend was retiring a Micron Millennia PIII system from ~1997. I was planning to use the qx6600 guts in the Micron Millennia case, but as I was looking at it, I would have needed a massive number of power adapters to be able to plug things in. I said fine, so what?, but then I looked at the 12V output on the PSU. I was short amps. It wasn't even worth buying the adapters to try it. I threw away the guts of the Micron Millennia including the PSU. In short it's going to be a rare 90's power supply that has enough 12V amps that it would be usable today even with adapters.The Micron Millennia case though, is very well designed. The fans clip in and swing out of the way on hinges, there's fans where they're needed. The drive arrangement is nice, the PSU is mounted on a hinge to make cable routing easier. There's plenty of drive bays. All the proper standoffs are there for a large motherboard. It's a really good case especially being from 1997. The only two issues were the power button quit working about 2 years ago, so I have a power button cable run between the side panel and the case, and the other issue was the standoffs for the motherboard are insanely long. I had to special order those so that I had enough to support my large motherboard.
I run a number of personal systems 24/7 doing various tasks for me and while idle performing computations for WorldCommunityGrid.org (curing cancer and such) My main system was powered by a PSU from ~2000. It was rated at 250 and I was pulling somewhere between an estimated 330 and 390 watts 24/7. It felt like it was spitting fire from the exhaust. To the credit of the Chinese no brand power supply it lasted for 16 months running 24/7. To replace that I bought an Enermax Platimax 80+platinum power supply, and about the same time I bought another 80+ platinum power supply for the qx6600. The energy savings have been noticeable with both, and they're cooler and quieter. Sorry, I don't have solid numbers to share,but I'm certain I've saved a large portion of their costs. The frustrating part is seeing reviews for 80+titanium power supplies at less than half the cost of some of the power supplies I bought.
I'm really glad 80+titanium power supplies are happening, but why now? What changed to make these possible? Couldn't these have been made back in 2000? Why weren't they? Or are things honestly that much better manufactured today?

I have often felt the same way, and I think it is just that now that prices have fallen so much, branding matters more. Also, the entire clear PC window case thing has people caring about aesthetics more.That said, modern PSU's are truly better than they have ever been. I am rocking and loving a Seasonic, and it is amazing just how good these new PSU's are. Your Platimax will likely last until the standards change.

Let's hope their eventual redesign won't be as bad as the X-series redesign was. I've had two fail (1 blew on first power-on, the other after half a year) while my original X-400 is still happy as ever after running out of its warranty, regularly driving ~400W of components.Freakie - Saturday, April 8, 2017 - link
In contrast, my 2nd gen X-750 has run like a champ for the last 4 years. My system also doesn't pull more than 450W so I keep the PSU power draw in the sweet spot which is why I got the 750W instead of the 650W.feelingshorter - Saturday, April 8, 2017 - link
I had the X-650, bought when it first came out in 2010 and used it in a computer that i rarely turned off until Jan of 2017 when I sold it. I payed $120 for mine at the time. But the competition is stiff and people are price sensitive, they do not want to hear why they need a PSU that expensive. I can imagine the company had to find ways to reduce costs on the X series, resulting in failures.I believe the PRIME Titanium series offered here represents the best the company can offer and we already know the company can produce a quality product, and quality costs money. The PRIME Titanium, at $160 shipped represents what the X Series was when it first came out.

They certainly appear to be awesome power supplies. I just wish someone would focus on the low power market for ATX power supplies. I realize as a heavy user, my rigs are rather lightweight, mostly because I have heavy use, but not rigorous gaming. My Desktop running a GTX750 and i5-3570@4GHz sips 122w with an Antec Earthwatts PSU under both gaming and Handbrake loads. I could probably push it up over 140 or 150w with something like furmark, but that doesn't represent a realistic load case. That is with a couple of HDDs, an SSD, 16GB (4x4) GB or DDR3 1866. No, not the most ridiculous system ever, but even if I slapped in something like a 1060 or whatever it is doubtful I'd push the system beyond about 250w.My server is running a Celeron G1610, an SSD and a couple of HDDs with 8GB of DDR3 (2x4GB) and an Intel ET GbE adapter. It sips 19w at idle with the drives spun down, 31w streaming to my AppleTV with the HDDs spun up and about 50w under max CPU load all with a Seasonic SSR-360GP.
Realistically most gamers probably don't even need something with more than about 400w of delivered power and most mainstream users/systems are looking at <200w peak. For some of these lightweight builds it would be really, really nice to see some high efficiency systems in ATX form factors that were targeted more at 100-200w range.
Even my Seasonic SSR-360gp as nice as it is, only manages about 75% efficiency at 19w and its power factor is about .72-.74
mjeffer - Friday, April 7, 2017 - link
While I agree 100%, it would be really nice to see some extremely high quality, lower wattage PSU, from my understanding it's a lot easier for them to hit higher efficiency ratings with higher power PSUs. However, I'd sacrifice the titanium efficiency for a lower power supply with the same top notch components throughout. I'd even pay good money for it. Sadly anything around 400W-500W is generally more focused on price than quality though some of the OEMs like Seasonic do make better ones in that range than you can find in your other brands.Mr Perfect - Saturday, April 8, 2017 - link
Yeah, it's the same thing down in the mITX space. My i7 + 1060 ITX is only pulling ~120ish watts while gaming. Something in the lower wattage range, and preferably in a SFX form factor, would be well suited. Other companies make them, but not in Seasonic's quality range.If I remember correctly, a Seasonic rep used to post comments on reviews of their products here, and he stated that they couldn't source 80+ Gold quality capacitors that would fit in SFX PSUs. I wonder if that's changed in the last few years.
SkipPerk - Wednesday, May 3, 2017 - link
I want to say that Enermax and Seasonic have high-end 400W units that are platinum rated. They are not cheap, but they are really nice. I want to say I saw a review of them compared, but I forgot where. Many of the high-end low power systems are fanless.Chapbass - Friday, April 7, 2017 - link
These units seem really cool, but the thing I really want to see is the 600w fanless unit. Wanted a fanless power supply for a long time.bji - Friday, April 7, 2017 - link
I understand your point of view, as I also appreciate fanless. However, just keep in mind that very few builds are going to stress these power supplies to a point where they'll even turn the fan on. I have a Seasonic 650W from years ago and I am not sure the fan has ever even spun up.JasperJanssen - Saturday, April 8, 2017 - link
Keep in mind the 600W fanless is probably just the 1000W model, minus the fan. Or maybe one of the others, but either way, it'll just literally be one of the other models minus the fan. *Possibly* with larger heatsinks, but I wouldn't count on it.emn13 - Saturday, April 8, 2017 - link
Higher rated PSUs necessarily have reduced low-load efficiency, even PSU's as good as these. So it's highly unlikely the 600W fanless is a 1000W model minus the fan; that would significantly reduce the efficiency at low loads, which, given their aim with these models, I seriously doubt is a tradeoff seasonic would have been willing to make.SkipPerk - Wednesday, May 3, 2017 - link
Seasonic makes a 500W fanless unit, but it is simply a 1350W unit without the fan and some big heat sinks. Enermax also makes robust fanless units up to 500W, but they are basically the same high-wattage unit with the fan removed and larger heat sinks. You might as well buy a 1200W or 1350W PSU that does not spin up until it hits a certain wattage (usually 300W to 400W).Lolimaster - Friday, April 7, 2017 - link
Considering they're titanium, most people just use 1 gpu and don't OC their cpu. They should launch more models, like 450-550w with fan.blahsaysblah - Saturday, April 8, 2017 - link
Not that i wouldnt have minded getting one, but read the wiki on 80 Plus. Gold is plenty fine. Im very happy with my SFX Corsair SF450 PS that has never turned on its fan(GPU is GTX 1060 6GB). Never seemed hot to touch. A good GOLD PS seems to not generate enough waste as heat to matter. Its almost one year since using it in new PC.Of course its positioned nicely, big vent up, for convection, per fine print, and its right under a vent, SilverStone SG13B case. One 140mm fan upfront is only system fan. Its does not get noisy level RPMs either. (just get silverstone atx to sfx adapter that is vented, centers PS, dont get corsair one. last i checked a year ago...)

Great review as always. Having a good PSU is essential for the longevity of the components. I mean, what's the point of the 16-phase VRM design of your MB if you are feeding it crap power? And how far can you overclock your GPU if your 12V line is full of ripple and noise? The efficiency is the cherry on top.Being a very satisfied owner of a Seasonic Platinum 850W, the only reason I'm not buying the Prime is because the Platinum is already extremely good and it's powering my home server 24/7 for years now.
Lolimaster - Friday, April 7, 2017 - link
You should probably change for the 10-20% efficiency, which your server will run at most of the time.That's why lower than 600w Titanium PSU's are more important than useless 750-850w where low load efficiency is not as good.
Looking at the numbers you're getting 90% efficiency at near 35w load on the 650w vs 90% efficiency at 55w on the 850w model.
blahsaysblah - Saturday, April 8, 2017 - link
Your math??Platinum only has guarantee for 20% and above, for a 850W PS at 20% load that is 170 Watts. Platinum guarantees 90% efficiency at 20% load so 170Watt load from PC would draw 189W at wall.
Titanium adds a 10% load guarantee threshold of 90% efficiency, so a 850W PS need a 85W(95W at wall) load to 170W(185W at wall, titanium gives 92% at 20%) load.
Exodite - Friday, April 7, 2017 - link
Any word on the pricing of the fanless 600W unit?I've been using a 400W fanless gold unit for quite some time and while I expect it to last many years still it's nice to have options.
It's unfortunate, if understandable, that the high-end supplies come with such high wattages as efficiency suffers under low load scenarios.

Well-written review as usual, offering a good balance between technical detail and readability. I have however noticed that you use the term "primary conversion bridge" in your PSU reviews.

Am i the only one who finds 40 dB(A) @ 50% load (300W) out of the question?Exodite - Tuesday, April 11, 2017 - link
No, though I've come to the realization that you have to treat dB measurements as an internal metric for each article/site and not an universal truth.Variations due to measuring methodology, equipment and ambient sound level means dB measurements don't compare well across different reviewers/sites.
Personally I prefer always-on equipment such as case and CPU fans to idle <20 dB and load noise, including GPUs, <30-35 dB so I reckon I'm in a similar position. Some reviewers, a surprising number even, have ambient sound levels higher than I'd tolerate even a fully loaded computer to make.
More than that dB measurements fail to pick up sound characteristics. A great fan/cooler can be tolerable at higher dB levels because the only real sound tends to be from moving air, a soft "whoosh" if you will. The bad ones add ticking or grinding, for example I find the default Radeon fans to be completely intolerable at any load level. And even fanless equipment may be saddled with electrical noise that cut right through the case and ambient sound.
In the end you really have to listen yourself to make a judgment and if that's not an option rely on a comparison to a unit you've heard yourself that's been tested by the same reviewer/under the same conditions.

u wont be disappointed with a 750 watt seasonic prime. The fans dont even turn on until u hit 375 watts of power draw. Which basically means even maxing out ur cpu isnt enough to turn them on. You have to play a game and most games utilize like on averahe 80% of ur cpu and yea the fan on the psu is dead silent when it does spin. Concentrate and getting a quiet GPU. Get a triple slot with GPU with a HUGE heatsink and adjust the fan profile till right before you hear it. The highe heatsink makes yup for the large speed. I really like the triple slot gpu's with 3x 100mm FDB fans plus nh d15s noctual cooler using liquid metal paste and the awesome titanium rated seasonic psu. With 11 blade fractacl venturi high flow fans with thge drave cages inside removed. this way you need no static pressure so even on low speeds the air pushes deep into the case and since its 2x 140mm inttake 1 140mm GP14 fractacl exhaust yu get positive pressure meaning you only have to clean the case once every 2-3 years as only microscopic particloes get in. You can run the fasn all at the lowest speed before you hear it even with good overclocks. I sleep right next to the bed thats how quiet it.
