Hey Guys, im currently running an oced 2500k sb which runs at 5517mhz thats coupled with Asus 6990 thats Oced to 930/1500. im running 2x320gb F1 + 1tb baracuda + 120gb Ocz Vertex 2 + dvd drive. There is 3x230mm fans + 2x140mm fans two of which have red leds, im using Noctua Nh14d as the cpu cooler with 8gb Gskill RipjawsX 2133mhz. Its all powered by a HX1000W that I think is not up to the challenge to handle my OC:-( i can oc the 6990 to 1000/1500 but only if the Cpu OC doesnt go over 5ghz. Above that i need to lower the gpu clocks to 930/1500. i Want to go 2x6990 and iimbwondering when oced how much power will i require with my setup? will a corsair ax1200w do the job and be up to the challenge?
