1.21 GW? 1.21 GW. Great Scott! How could I have been so careless? 1.21 GW, Tom? How am I gonna generate that kind of power? It can't be done, can it? Marty, I'm sorry, but the only power source capable of generating 1.21 gigawatts of electricity is a bolt of lightning. A bolt of lightning, unfortunately, you never know when or where it's ever gonna strike.
The use of a C19 cable instead of C13 is required to comply with IEC 60320. C13 is limited to 10A of current, or 1100/1200W of input power. C19 bumps the max to 16A.
This would be a problem for New Zealand power points, as our max current draw is 10A @ 230/240. Only power point in our house that allows for more than 10A is the oven and hot water cylinder.
Because you're at a higher voltage. You won't have a problem. 10A in 230v means 2300W. That power supply will draw maximum of 7 amps from the wall (1500W at 92% efficiency means 1620w from the wall, at 230v it means 7 amps)
Article starts with "making an 80+ PSU is much cheaper and easier than it used to be" and then here's Corsair with their ridiculous $450 PSU for the 0.01% of people who incorrectly believe they actually need this much power.
It will mostly be of use for people who are using quadruple GPU configurations or highly overclocked triple GPU configurations.
But yes, as the article notes, it's a niche product and arguably an overpriced product for what it offers. We'll see what similar 1500-1600W PSUs offer by other manufacturers in the coming months.
Good, you mentioned, almost. I've build recently dual cpu (using Supermicro X9DRG-QF), 5 GPU (Titan black) workstation, water cooled (for sake of efficiency and longevity, not wow factor), and it refused to boot on Corsair AX1200i, switched to dual Seasonic X1250, and it peaks around 2.1kW from wall (on 230V).
Assuming you're running an SSI EEB board, you should really be using server-grade EPS supplies rather than this consumer junk. Drawing 2.1kW from the wall is all the evidence you should need for this! ;)
Just because you don't give a crap about efficiency doesn't mean others won't. Going from 84% to 92% efficiency on a 500W load is over 1.2 kWh saved every day. At $0.15 per KWh, the PSU will more than pay for itself within the warranty period.
Why would a power supply need accessories? When I'm buying a power supply the unit itself is all I care about. Bundle a power cable that won't burn the house down and I'm good. The case badge, screws and bag are totally unnecessary.
I consider spare cables with different plug configurations, if PSU is modular, a very good accessory. Screws always come in handy - if you don't need them just shove back in the box, but sometimes you have to build in the wild, where you don't have any extras. Over the years I accumulated nearly geological layer of such accessories from hundreds of devices, but sometimes it just happens you need them. Of course if you throw them out (or don't get them in the first place), there will be time you miss some :) And sticker is always handy too - I have a friend that's sticker junkie, his PC looks like it had accident at the printer shop)
Gotta agree with the extra cables. A few 2/3 port molex/sata cables mean a lot less having to manage extra cable when you don't need all 4 ports on them. I've seen some vendors offer an alternate cable package (different plug counts, shorter cables, extra long cables, extenders, etc); but at this price I'd expect to see at least some of that tossed in.
For that matter, why is modularity limited to the PSU-cable connection itself. Make a few cables that will let you break off the last connector or two to shorten them.
It's probably cheaper to just include a bunch of cables with shorter run/fewer terminations and be able to use standard components, than to engineer a completely new terminal with a breakoff/attachment point just to be able to provide a shorter cable.
All they'd need to do is take molex Y cables, and put both downstream connectors on the same cable; and then do the same with sata power connectors. No major engineering effort needed.
What a sloppy review. It reads like an impassioned love letter. And hardly a comparable product mentioned or charted.
My comments shouldn't be taken as directed at the product - I have no quarrel with the power supply - just the squishy drivel being published in an attempt to describe it.
Question: Stipulating an identical draw of power, would this PSU, compared to a similar PSU with a lower max output, result in less heat generated?
An example for clarification: System X draws 500 Watts. Would there be a difference in total heat generated, whether System X had a 1000 Watt PSU or 1500 Watt PSU? The assumption being the quality of both PSU's were almost identical
Heat losses depend on the quality of the PSU components and its ability to sustain such power efficiency at different power draws, so I believe the short answer is No, it shouldn't matter. This reviewer says that this specific power supply provides for good efficiency even at low power draw, meaning that it generates little heat regardless of whether your load is 200 or 1500 watts.
Of course your hypothetical 500W system will draw 500W at times, but maybe only 50W when idle...
The advantage of having more power than you need is to let the components breathe better, widen the pipeline so to speak. You may not need 1500W, but the extra headroom provides for stabilty and overclocking potential.
>>The advantage of having more power than you need is to let the components breathe better, >>widen the pipeline so to speak. What? This is audiophile-grade fluffy language. And a load of...
>>You may not need 1500W, but the extra headroom provides for stabilty and overclocking potential. ...bullsh!t. You either need 1500w or you don't. If you're overclocked setup draws 600w from the wall, having a 1500w PSU is not going to improve stability or overclocking.
Maybe he worded it with some level of ambiguity, but the point he wanted to come across can be easily understood.
If your overclocked setup draws 600W from the wall, theoretically you can have a 600W PSU supply all of that without the PSU going out of regulation. However, if you still have some room for additional overclocking (from better cooling), your overclocked setup might draw an additional 50-100W, and your 600W PSU (depending on its quality) won't have that headroom to sustain the additional power draw, which would lead of course to instability.
So what you're avoiding is the PSU becoming a bottleneck when you still have the capability to overclock further.
But the fluffy language he uses let's me rather suspect he's one of those people who believes a higher powered PSU makes his PC faster. Because moar power!!!
Like the audiophiles who think a super-expensive HDMI cable that is thick as a child's arm is improving colors and clarity of their blu-rays.
Maybe. If you've got a low power system with a decent smaller PSU this would probably be worse becuase you're in the sweet spot for the smaller PSU and in the low-load suck range on this monster. if you're running a 500W box on a 550W PSU, this would probably do better at full load since the 550 would be in the nearly maxxed out suck zone; OTOH the 550 would probably still do better at idle. You normally get peak efficiency around the 50% point and good performance from 20-80% before falling off at either end (see the curves on pages 3/4).
80+ Platinum is the first 80+ spec to set an efficiency requirement at 10% too; and platinum units generally do a lot better at low loads. OTOH since they're all still halo priced; unless you live somewhere with really expensive electricity they're not going to pay for themselves vs more mainstream models.
Great product, but the price is only meant for high-end workstations and the like. I think it would be useful for such extreme products to enumerate the connectors.
I am asking this because I was looking at the ASUS Z10PE workstation MB supporting dual Haswell Xeons with massive 150W TDPs. The MB in question requires 1xATX 24pin, 2x8pin EPS AND an optional but recommended 6pin EPS 12V connector for SLI/Crossfire. I haven't yet found a PSU with a 6-pin ATX 12V power connector, and I am almost certain it's not the same as PCIe.
Running this PSU to power my watercooled quad-Titan Black workstation running CUDA calculations. PSU remains surprisingly quiet and mildly warm to touch even under full load.
What a beautiful piece of hardware; fantastic to see something pushing so hard at the bounds that define 'well made'. Cheers for the review, was fantastic H/W pr0n to read :D
As somebody who has previously worked for a power supply company (not these ATX form factors though), designing very high efficiency PSUs like these is hard as HELL. You're not going to enjoy designing and testing these when all you're missing is that +1% efficiency for certification purposes.
Even small benchtop welders need double the power of something like this. Bigger free standing models start at needing a 50A-220V circuit for input (and presumably go up from there).

wow this is really tempting to pick up just to be compleatly fanless at around 600 watts or less! that justification enough to pick up a $350 dollar power supply thats 3x the power than i'll ever need right? .........right??
"Unsurprisingly, Flextronics is the OEM behind the creation of the AX1500i and..." -------
I tend to buy about 40 power supplies a year from Corsair simply by the fact that they use Seasonic in the ones I like.. Unsurprisingly I won't be buying any more Corsair power supplies. It's that simple.
Wait, what do you have against Flextronics? They generally make better PSUs than SeaSonic on the consumer market. Not only that, the AXi series (and the AX1200) are the only series made by Flextronics. The rest are still made by SeaSonic and CWT.
1500 watts? I would think that we are just below the limit of a normal CCT Breaker (15 amps) in a normal household. Add a printer, displays and you need to change the wiring and the CCT breaker. You make reference to 107.5 amps, do you realize the size of wire for that amounts of current that is needed. Strange review, and useless power supply.
