1000W-1200W Roundup: Five High-End PSUs

| Sound Pressure Level | |

| 100% | 32 |
| 110% | 37 |
AeroCool is audible at all loads, and the fan always spins at 600RPM or more. It hits 30dBA starting at 80% load and hits a rather annoying 37dBA at overload - with some noise from the electronics thrown in for good measure.

While the power factor correction is very high, the efficiency is rather poor below 20% load. The performance is still enough to get 80Plus Bronze certification, but if you're spending this much on a PSU we would expect better. We don't think most of our readers would be particularly happy with this power supply, as the results are disappointing at best.

Martin,
Just curious, how do these PSUs compare to existing units which have been out for
a while, eg. the Thermaltake Toughpower 1000W Modular? Any thoughts?
Ian.

Hey,apart from the fact that the Thermaltake (CWT 2x 500W Design) is less efficient than most actual PSUs, the voltage quality is almost perfect.
DC-DC, good caps and filtering, not faraway from Corsair HX. A proven design.
Cooling could be better, since many components are close together. However, still uncritical temps.

It would be great if Anandtech could do a roundup of a few 550w to 750w PSU units, as most mainstream users are using PSU units within this wattage range.
