So I've recently bought a ASUS Crosshair V Formula-Z AM3+ AMD 990FX as well as a CX750m corsair psu. My question is I have the 24 pin plugged in as well as the 8 pin, the mobo also has a 4 pin and a 4 pin molex. My PC will not boot a monitor and I'm wondering if its not getting enough power because I dont' have the 4 pin or the 4 pin molex plugged in?
