Testing:
The old way of testing Power supplies with a wing and a prayer, is no longer sufficient in the tech savvy world we live in. People want to know just what kind of power a supply can actually deliver and still conform to the ATX specifications. With a new testing methodology, OCC will move into the future to provide a more current testing regime, to accurately show how a power supply performs. For more information on our testing methodology, please browse our testing methodology.
NOTE: The -5V0 line is no longer required in the ATX12V V2.2 standard and will be totally disregarded during testing.

You can see the 3V3 and 5V0 lines have dropped below the ATX12V V2.2 lower limit and 12V0 lines are approaching it. I considered loading the power supply closer to its maximum but due to problems I’ll explain later I decided to stop at this level.
