I have an Antec NeoPower 650. It has been running well with a Phenom X4 9950, 8 gigs of ddr2 800 ram, a radeon 4870, and a single 320 gig hard drive ( I really have no need for more than that but I want more). I am looking to upgrade my system, but I don't know much about power supplies. Will this power supply be enough for an i7 920 OC'd to 3.2 ghz, a 1TB hdd, radeon 4870, 6 gigs ddr3 1600, cooler master haf 932 case, and cooler master v8 heatsink? I would appreciate any help or non-biased opinions.
