Recently my rig has been locking up during bouts of intense gaming. I get the its-a-lockup noise and my video dies.
Originally I thought the problem was video related. Turned out to be a bad cable. Now I believe the issue is with my Cougar CMX1000. I ran some tests with OCCT to narrow it down.
The GPU test ran solidly. No errors.
A power supply test reproduces the crash. Voltage readings seem low. The 12v sits around 11.7, the 3.3v around 2.91, and the 5v around 4.36. Are the on-board readings biased? I've heard claims they read .2v too low compared to a multimeter. I haven't tested with a multimeter.
My psu is currently powering an i7 950 at stock voltage and 2 GTX 580s as well as the water pump that cools the both. I think I was cutting it close with the wattage when I built the pc. Could the psu have aged to the point where it can no longer do its job?
