Testing (Continued):

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 a power supply is installed in a case, which, by the way, it wasn't for testing. Ambient temperatures, 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 TX550M remained cool and quiet at all times, even with the unusual behaviour of the cooling fan that didn't vary throughout testing. The marginal speed increase at full load indicates it was perhaps on the verge of ramping up, though the introduction of a little warmer air into its intake from the load exhaust caused a noticeable increase in speed.

The TX750M remained cool and quiet throughout testing, assisted by the cooling fan maintaining a relatively low speed of only 1500RPM at full load. No problems here, so let's move on.
