Testing:
Temperature, Noise Levels and Fan Speeds:
I am not going to give a pass or fail in this section, as the ATX12V V2.2 does not really have any references on which to base a decision.
Temperatures are purely for information only, as there are too many variables involved when installed in a case, which, by the way, it wasn't. Ambient temperature, processor cooling efficiency and case cooling fans all play their part on the temperature of the air entering the power supply, and consequently the temperature of the air leaving it. No valid conclusions can be made from this test.

The temperatures of the Antec Truepower Quattro 1200W did remain quite low but the use of a 80mm cooling fan means one thing, noise. Loading at approximately 50% produced a fan speed of 1800RPM, a little noisy but bearable, but when fully loaded the fan speed ramped up to a very noisy 3200RPM. Very few people will use this power supply at or near full load but if you do, be warned, the cooling fan is probably one of the noisiest I've heard!
