Pvtbrutus: What is the amperage of the current PSU I'm using? I can't find it anywhere on Newegg's site, but I do know this PSU was recommended by JohnnyGuru.
Its mentioned on newegg under details:
+3.3V@20A, +5V@20A, +12V@99.5A,
-12V@0.5A, +5VSB@2.5A
This means it has one 12volt rail which can provide 99.5 amps. 12 x 99.5 = 1194watt. This falls in the "good psu" category. However i would still recommend trying a different PSU if possible to rule out a quality issue.
