Short Circuit Protection:
I short circuited the 3V3, 5V0 and both 12V lines in turn. The power supply did shut down, and once the short was removed and the unit switched off for at least one second, it 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 DC voltage load regulation of the Xigmatek NRP-PC502 was acceptable and all rails remained within the limits set out in the ATX12V V2.2 specification up to a 471W load. The performance could be better however, with the -12V rail a little on the low side at light loading, and the +12V rails approaching the maximum limit when loaded at 471W.
