The Cougar is as silent as the OCZ at low loads, but it's louder at 100% and 110%. However, the GX series is still quieter than older designs with common Young Lin fans. It is nice to see less than 20dBA beneath 50% load.

With 89.79 % Cougar doesn't quite reach 80Plus Gold - unless you round up. Overall it does okay, and PFC is very high with both input voltages. The only real point of criticism is the low efficiency at 10% load (about 105W load); we'd recommend running high-end setups that idle at around 200W or more to get optimal efficiency from this PSU.

    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?

    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.
