hi to all: i have been unable to test the vrm, cpu or video card, but i was able to test the PSU. thanks to Dave Kuebler, who explained how to do it, i found out that the out put is 16.9, not good news. for starters, i need a new PSU, and once i have that i can start testing the components. if anybody has a good PSU for sale, please lml thanks to all you have been helping me figure out what is wrong with my cube. g
