Testing:
For more information on how we test our power supplies, please browse our testing methodology.
Short Circuit Protection:
I short circuited the 3V3, 5V0 and the 12V rail(s) in turn. The power supply did shut down, and once the short was removed and the unit switched off for at least one second, resumed normal operation. Although listed here at the beginning of the testing section, I tend to leave this test until the very end, in case it doesn't quite go to plan.

The voltage regulation of the Topower 1000W power supply isn't quite as tight as some high end units tested by OCC but it remained inside the limits set down by the ATX12V V2.2 specification at all times. No problems here, so let's move on.
