Testing(Continued):
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 noise level from the Cosair HX520W cooling fan was at all times very quiet. When loaded at 506W the fan only ramped up to 1343 RPM, which I could hardly hear. Noise levels are, of course, my personal opinion, and what I may consider quiet could quite easily be considered noisy by other people.
