Didn't think to check this before, but I'm getting ~112-113 volts into the PSU from the surge strip. I'm probably going to get a new PSU today. The parts store has a couple of 400 watters in the $50 range (a fortron and a thermaltake). I did a lucifer burn-in test last night and got 8 errors over a two hour period. I ran the mprime torture test this morning (after the computer had been powered off overnight) and it passed. I didn't have the high-low meter attached to see how the voltages looked. Thanks, Micah
