NightGod:
In this instance, use the computer case as your ground-just touch the other end of the paper clip to anything bare metal in there.

actually, no, it wont' be the same ground, as the psu cable is unplugged. Use any of the black wires that lead to the harness as ground, it won't matter which one.

Actually, yes it will-I used this test method on dozens of different machines before I finally broke down and bought a PSU tester and I always grounded it out to the case. As long as the PSU is still attached to the case, the case is grounded to it-alternatively, you could ground it out to the metal shell of the PSU if you have it out of the case.

Sure, IF you leave it connected to the motherboard, which I wouldn't do while testing a powersupply. Also, if he followed Peale's directions
--- Quote from: Peale on July 09, 2007, 10:44:10 am ---If it's an ATX, unplug it from the motherboard and all drives. Take a paperclip and short pins 14 and any ground together. Pin 14 is usually a green wire. If it powers up, you have other issues.

and is confused which wire is ground, then touching the chassis of the PC isn't going to work. I'm not splitting hairs purposefully, but if he's having issues troubleshooting a PSU, consistant information is key to solving the problem.
