What is the rest of the system specs.

If you have an i7, 8gb (4gbx2), high end mobo, DVD-RW, and normal 7200rpm harddrive with those two gtx 680's the math equals to a recommended wattage of 770w

You want a really good 750 watt.

But my question is, if you can spend that much money on two GTX 680's, why skimp on a power supply? Thats Probabaly the worst thing to do.

I can tell you that an i7 X58 at 1.36250v and 2GTX670 at 1.2120v with +145% Power Target; full stress on Prime95 and Kombuster I am pulling from the PSU (Corsair AX860i so it has a digital output to tell me), I can draw 760w.
