Foremost, current system:
MSI GTX 580 Twin Frozr II
Asus P8Z67 V-PRO
G.Skill Ripjaws (2x4GB) 1600mhz CL9
Samsung SpinPoint f3 1TB
Crucial M4 128GB
Overclocking. Most probably over clocking the i5-2500k to a stable 4.5ghz. Not planning to over clock the gtx 580 until I know what I'm doing.
Not planning to SLI since my mobo can't have x2 x16/x16 slot anyway.
So, that said, is the Corsair HX-750W PSU sufficient? or should I ramp it up?
