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.
