I have a Thermaltake 700w Bronze power supply and a XFX DD HD 7850 2GB GPU. While running Counterstrike GO and other 3d applications, my 12v in GPU-Z dips from 11.66 to 11.41. The highest it goes when idling in windows is 11.66. Is there anything I can do about this? Is there any kind of software setting that could be doing this or do I have a stinker of a PSU? I knew thermaltake PSUs weren't stellar but it was a good price. Could it be the 4+1 power phase of the mobo instead? Videocard is NOT overclocked.
