So I modded a psu into a bench test supply, and I put a dummy load of 5 ohms on the 5v rail, and the psu would shut itself down after 20 seconds. Then I put a 22 ohm resistor on the 12v rail instead, the psu turned itself off after less than 10 seconds. Then I tried both resistors at the same time and it still turns off. Am I missing something or is the supply busted?
