As the title says, I am supposedly drawing way more power than my PSU can handle at full load. My system consists of an AMD A6-3670k overclocked to 3.8Ghz @ 1.5v, an XFX HD 6870, 2 2.5" 7200 RPM drives, and several fans. Can someone enlighten me as to what is going on? (I know that it runs at 80% efficiency, but even accounting for that, it would still be drawing ~750W)
