I have had many issues with temps with my 4770k over the past few months. I had an idea, hooked up my Kill-A-Watt, and plugged in my PC only to see that my wattage was around 120 Watts. It was around 112-120 idling, doing absolutely nothing. On full load (Prime95 and Heaven full settings) it uses around 500 Watts at the absolute most. It hangs around 480 and occasionally hits 500 depending on the scene. Of course this was with both GPUs rather heavily overclocked and my CPU with a decent OC. I then disabled one GPU. I saved a few watts there, dropping to 108. I took both out and reset to default settings for everything. I turned on the C states and power saving, and still stayed around 70 Watts. 65 was the lowest. This was JUST my CPU and RAM at stock at 800 MHz / 0.772 Volts. Could this outrageous power usage be the source of the crazy temps?
