Power Supply Roundup: Eight 1000W for the Extreme Users

Product Comparison: Acoustics
The acoustic graph shows more distinct results than the efficiency graph. We have many low noise power supplies and Akasa seems to be the lowest one. With a stable 19dB(A) throughout the test it's quite amazing, but it makes us think: if your fan doesn't start turning faster your power supply will most definitely get hotter inside. Looking at the green line of the similar Strider power supply, the fan starts to turn much faster at 700W and therefore cools the inside better. All other power supply perform reasonably well with noise levels under 24dB(A) most of the time. Only the OCZ ProXStream sticks out from the mass again, this time in a negative fashion. With normal operation starting at 35dB(A) and increasing to 45dB(A), this power supply never get silent and can end up quite loud. The Ultra X3 and Enermax Galaxy - and to a lesser extent the Enermax and Kingwin - start out quieter but above 500W begin to increase in volume quite rapidly.

Depending on what site you check, I think you would find that very few 1000+ watt PSUs can sustain that output under load in real world conditions 100v to 120v. I am somewhat skeptical of that fact that 8 PSUs got tested here, and not a single one was labelled as a failure to provide on the rated specs.buzznut - Thursday, December 13, 2007 - link
So we have a line-up of 430 watt supplies, a comparison of 750-850 watt models, one of 1000 watts, and the "extreme" Power supplies at 1200W+.Anyone else notice the little gap there?
What about the 500-700 range, arguably the most popular with system builders right now? I can't even fathom why you would choose to ignore this segment.
Do ya think you could cover the more relevant enthusiest segment since this site is viewed by many enthusiests every day? I mean the ones that don't have $300 to blow on a power supply when a 650 watt one will do the job. Or ones that don't receive their equipment for free because they review hardware...
I buy a lot of equipment every year but I am not wealthy. I get tired of reviewers who tell me about the latest 700 dolla video card or other stuff I'll never be able to afford.

Nice touch adding in the Euro prices, a welcome change, infact a first in over 8 years of readership i think.Just a quick point, i think the import duty allowances on purchases abroad are very low, so flying to the US is fine for a holiday, but unless you are prepared to break the law and claim it as your pc you took out or something, then you would have to pay duty and vat as if youd had it shipped. Add to that any warranty claims may be null or awkward to service then it may not be the bargain it could be.

Wasn't really meant you would need to book a flight to go the States to buy a PSU... Of course there are import taxes (19-19,4% for France and Germany).PolymerTim - Wednesday, December 12, 2007 - link
Is there a power supply roundup coming out any time soon for something like 400W-700W. I've been reading through the PS forums lately and it seems like a lot of the recommended PS fall somewhere around the 450W-650W range and this seems to be missing from the roundups. I realize there were a lot of individual reviews in this range not too long ago, but there are several new options in this range in the last few months that I think deserve a review a bit more than yet another "ultra high" or "extreme" roundup. Just for illustration, I posted the date and title of every anandtech PS roundup since the new PS test methods came out 5 months ago. See the gap? We have 3 roundups between 730W-1300W and 1 roundup at 400W-450W.12-11 Power Supply Roundup: Eight 1000W for the Extreme Users
11-22 Power Supply Roundup: 730W to 900W
11-06 400-450W PSU Roundup
10-22 Ultra High-End PSU Roundup (1200W to 1300W)
Of course, many PS in this range were reviewed, but never in a roundup compared to other similar PS.
09-14 Seasonic S12II: 330W to 500W of Silence
09-11 Enermax Infiniti 650W
09-03 Zippy Serene (GP2-5600V)
08-27 Silver Power Blue Lightning 600W
08-08 Silverstone Decathlon DA650: A modular alternative
07-30 The Enermax Liberty - Getting long in the tooth, but still worth a look
07-24 Gigabyte's New Odin GT 800W Power Supply
07-18 PC Power & Cooling Silencer 750 Quad CF-Edition
07-13 The Single 12V Rail SilverStone Olympia OP650

Yeah this year still 600-650 watts...halcyon - Wednesday, December 12, 2007 - link
How about also another type of article:How to build a computer that does 90% of what people need (sans games) and runs on less than 30W?
800-1000W is insane and people should come around to understanding that.

I'm pretty sure even most laptops don't draw that little power. Not sure on the newer C2D processors, but I know the older Dothan Pentium M processors had a TDP in the 20-25W range. Add the rest of a system and you likely won't spend much time below 30W.Or check out some carputer setups. Using VIA mini-ITX motherboards with integrated processors and graphics and they still typically use 90-160W power supplies.

At idle, most of the moderate notebooks (14-15" chassis) sit at around 25W. Load, they'll get up to around 60W with IGP and 100W with something like an 8700M GT. 8800M GTX will probably push that closer to 125W (give or take 10W).jonnyGURU - Wednesday, December 12, 2007 - link
I'm game (no pun intended.)I built a machine with all on board components, a mobile AMD chip and solid state drives and it still required over 200W to run. Mind you it had a 7950 graphics card, but still.....
