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 Xigmatek NRP-PC402 remained cool and quiet throughout testing, but it wasn't installed in a case, so please take this into account. I have included the graph on the side of the box for reference. 1600RPM at 100% loading is probably a more realistic figure, but even at this speed, it will be quieter than most power supplies in this class, helped no doubt by the high efficiency.
