Re: What would you place your bet on it being?
Jayce, I bought a digital multimeter for $19 at Radio Shack, and it works like a charm for testing PSUs. That would give you definite voltages to your various molexes, the mobo connector, et al. Since that is a bit of a cheap tester, I wouldnt necessarily trust it completely. I mean, it might be ok, but for under $20 for a multimeter you cant go wrong. Better safe than sorry, and then you could rule out the PSU if voltages turned out ok.
