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.

Temperatures are comparable to other power supplies in the same class and I can't foresee any problems in that department. Fan noise, in my opinion, is quite reasonable until you fully load the TX750W, at which point the fan ramps up to 2016 RPM and becomes noticeably louder.

The Corsair TX750W is fitted with a clear plastic fan baffle that covers approximately fifty percent of the total fan area and I have to ask, is it really needed? The reason for its inclusion must be to improve cooling but I couldn't help but notice a quite powerful airstream leaving the fan in the area of the baffle. This isn't the first time I've seen the baffle fitted so just out of interest I removed it and ran the power supply at full load for over two hours and the only difference I observed was a reduction in fan noise, temperature difference was negligable. This is just an observation and I don't advise anybody attempting to remove or run the power supply without the baffle, the designers must have their reasons for its inclusion, even if I can't find it!
