Got a friend selling these pretty cheap, thought I'd pass it along.

BTW, Early on I had a PC die, power seemed OK, but the mother board was dead. Without a thought in the world about the power supply being the cause I replaced the board and it promptly died. My buddy, who sold me the board (new), told me a number of points where I must have screwed up and placing my faith in him I said I'd replace the board (again) but after saying the board may have been bad to start with. Taking this as an insult to his pride, he took the a new board off the self, tested it, installed it and it died. At that point he went looking for the cause and found that the power supply was pumping some odd over voltages on the 5 & 12 volt circuits. Apparently not enough to kill the fan or the HDs, just the mother board. He was some what embarrassed and as a way of joking about it bought both of us pocket sized voltage test meters (still have mine).

So in light of a number of recent post about power issues, I offer this.
