I think my Antec 650 watt PSU power supply started to go on Thursday night. Friday morning when I tried to turn on computer I was not able to get any video output. GTX 660 wasn't working. I then took it apart last night to make sure all of the wires were together to see if I had accidentally disconnected something, but when I rehooked the PSU up and hit the power button I got no fans, beep etc. I have been building my systems for a while so I am not a "noob". I was afraid it was the MB or video card, but I did the paperclip test and the PSU fan did not kick on at all after numerous tries. Is that the best "Test" you can do albeit getting some type of gauge/monitor?
