[QUOTE="wenoc, post: 4079247, member: 44188"] A multimeter might not neccesarily give you any useful information. The powersupply might work well under a light load but under slightly more stress the voltage might drop. I had that problem on one computer some years ago. If you've tried the voltages with everything connected and powered on, and it still checks out though I guess you're in the clear. I assumed you've measured it all by itself. That computer of mine was fubared and slightly in the same way as yours. It was a mix of fried motherboard and powersupply in the end. Powering it on wasn't reliable, sometimes you had to disconnect the powercord from the supply to "reset" it and get it to power on again. Apparently there was some thingy with the ATX-thingy in the motherboard which wasn't sure if it was on or not. In the very end it refused to power on at all if you had too many devices connected. Just because I wanted to, I switched in the harddrives two seconds after the mobo, and that way it started perfectly, which would indicate that it needs more power in the very start and couldn't handle the stress. For the record, the supply should have handled at least twice the amount of power output compared to that system. The whole avalanche of increased faultiness started from a faulty Palmpilot USB cradle that was not connected to ground properly (they replaced all those cradles later) and caused serious static when the palm was inserted into the cradle. It fried the USB controller immediately. Oh well, sorry for the wall of text. [/QUOTE]
