I have an old PSU that when plugged into its motherboard begins to power-up, then dies whenever I push the PSU power button (on or off). The power-up before dying only lasts about 1-2 seconds. I would like to test the voltage of this PSU, however it's on old PSU that has two connectors (marked PS-1, PS-2) that plug into the motherboard that are too narrow to allow my multi-meter prods to get inside and touch the metal ends. Is there another way to test this old PSU to determine if it's bad, or if it's something on the motherboard causing the PSU to fail? All I have connected to the mobo. at present is the Battery, CPU, RAM and the original card that plugs into the mobo. that has all the ISA slots on it. The PSU and mobo. are original to the computer case and worked fine a few years ago (running Linux).
Anyway, I'm used to testing PSU's with a paperclip and/or multi-meter but the connectors on this old PSU are smaller/different than the newer PSU's I've tested before.
