I can't imagine buying a 1000W power supply at all. My current 850W is overkill even with a Vega 64 in my system. Most people will never even use the 650 Watts required to hit peak efficiency on this 1300W beast. What we need are power supplies that can provide 90+ efficiency at the 50 to 60W idle most of our PC run at these days. Power supplies like this are for what, crypto mining? Servers typically use a completely different form factor, SLI is dead, so yeah mining...
well, you will need more than 1000W don't forget other components and overhead. but future cards will reach 500-600W and even more. getting higher wattage PSU is good idea but I would wait for PSUs that are fully compliant to ATX V3.0 .
You are right. But I can't fathom building a computer that draws that much power. It just feels crazy to me and I don't even live in a very warm climate. It really is just that the energy we are talking about feels crazy. Most plugs in the US are 15 Amps max, so we are getting to the limits there.
With energy prices exploding I can't wait for the already overpriced GPUs to ramp up 600W. They'll sell like *very* hot cakes. Perhaps they decide to switch to smaller nodes, or [gasp!] actually consider efficiency!
Just wait until you see the power requirements for the RTX 4090. Rumoured to be 450W to 600W on its own. RTX 3090 requires 480W, but when you factor in its transient loads, this requirement can go above 500W. It is generally recommended to run a minimum 1000W PSU with an RTX 3090, if you don't want to crash during a transient spike.
Water cooling will pretty much have to become the standard for flagship GPU's, even with GAA coming after 2025 (And might still take a while to reach consumer GPU's).
The General Appropriations Act? What does the Gaelic Athletic Association have to do with GPUs? The Georgia Alternate Assessment can't help at all here.
But seriously, AMD was apparently eying Samsung's 3nm GAA for Zen5. Then again being Samsung I'm sure they probably squeeze less from GAA than TSMC is from FinFET. And I doubt that GPUs will see that anytime soon.
If you crash from a 500 Watt transient spike and you have a normal desktop CPU with a 750 Watt or more power supply. You probably have a crappy or defective power supply.
I had a 750W PSU with a 3090 and a 5950 and it would regularly (once every few days) trigger the overcurrent protection and turn off. It was one of the best seasonic PSUs money can buy. I saw other instances of people with the same problem.
The 3090 is known to hit transient spikes up to 600W, and when you couple in 100+W for the CPU, then MB, RAM, hard drives, etc. You can *trivially* go well beyond 750W.
The 2% difference translates into $2 per year for each hundred spent on electricity - so if you have a 10 year warranty (like on most Titanium rated supplies) you can probably afford to pay an extra $40 to move up a grade, and to overprovision a couple of hundred watts. It's likely that $40 won't quite cover the difference between the two power supplies but the doubling of warranty and lack of need to upgrade in the future can be worth the extra cost.
You could also just buy your power supply from the well known company that supplies components to most of the OEMs, certain models are priced very much lower than other brands; just a matter of taking the time to compare.
People also cannot imaging needing something like a 3090 that is $1500 retail. But we have it. And they sell like hotcakes. They have some crazy transient loads and 4090 might turn into an insane doozy with DOUBLE the Cudas!!!
When will we stop seeing irrational designs like this PSU?
The reviewer heaps praise upon a design that is suitable only if one cannot hear. Stuffing so many watts into a small box is foolish. Reliability is meaningless if you get tinnitus and noise pollution.
"This particular model has a maximum speed of 2150 RPM, which is a high rotational speed for a 120 mm fan, but it should not be reaching that speed under normal operating conditions."
With over 100 amps on the 12v rail, I'm curious what happens if a sata connector comes uncrimped and shorts or a cap goes short circuit. Can the supply even detect shorts (which are probably well under 100a) or will it pump in current until the wiring is on fire ?
Well, it's made for a "under the desk" tower case. Such is both far from the user, and there's no "direct" sound path (only reflected). So the perceived sound level is far from what - let's say - a gaming laptop would feel like (Asus Rog Zephyrus 14 will go 46 dB within your arms reach, and the highest noise from the PSU was some 52 dB under a desk somewhere. That's four times the perceived noise level in the same conditions - which, in this case, are not.

Yes, if you have a Threadripper that pulls 400 Watts peak and a 3090 that does 500 Watts peak, you need a 1000 Watt power supply.Eliadbu - Saturday, March 12, 2022 - link

Yep, i built a threadripper 32core system with 2x 2080Ti, it will go over 1000W and shut the system off.at_clucks - Wednesday, March 16, 2022 - link

If you look at the efficiency ratings at 50% a Platinum will get you 92% and Titanium 94% at 50% load: https://en.wikipedia.org/wiki/80_PlusThe 2% difference translates into $2 per year for each hundred spent on electricity - so if you have a 10 year warranty (like on most Titanium rated supplies) you can probably afford to pay an extra $40 to move up a grade, and to overprovision a couple of hundred watts.

Probably not until the first GPUs start shipping with them.Threska - Thursday, March 10, 2022 - link
That fan location is good for those cases that have the cutout in the case. Mine currently has the fan on the switch side.back2future - Friday, March 11, 2022 - link
"This particular model has a maximum speed of 2150 RPM, which is a high rotational speed for a 120 mm fan, but it should not be reaching that speed under normal operating conditions."Astonishingly (relative) small heat sinks.

It’s too loud.I have put PCs into closets and in adjacent rooms. I am very familiar with desks, baffles, and other obstructions.
