Allways try and add a wattage test on a upgrade, so here's one from my gigabyte windforce sli gtx 670's.
Wattage is tested from the wall with a digital wattage meter.
I've used the average wattage so the watts have actually been anywhere from -/+ 50 watts, higher the load the more chance of the watts being more or less.
Using sigrig
Cpu o'd using speedstep, max cpu volts are 1.28 for 4.4ghz, 3770k and z77
Idle
120 watts
Heaven benchmark at stock
Core 1175mhz
415 watts

Heaven oc'd, core +75=1250mhz core, power limit +111
460 watts

I'll get some more testing done when i've played some games
