Im building a gaming rig that consist of a cooler master storm trooper case, NZXT HALE 90 850 watt psu, 2 radeon 7850 gpu's, amd FX8150, 4 x4 GB CORSAIR Vengence 1866, Asus crosshair V motherboard, Corsair H100 cpu cooler, Corsair GT solid state, asus optical drive 24x dvd, 320GB western digital caviar green and Asus Xonar phoebus soundcard. I also plan on overclocking my GPU and CPU Not too the extreme but better then stock. First of i would like to know if my NZXT 850W PSU could handle the gear i have. My second question is how can i moniter how many watts my computer is consuming in the operating system. Leets say im only using 700 watts how would i find that out?
