Hey everyone, quick question, i have a p55-gd80 mobo and core i5 750 waiting and i'd like to order a new psu soon for delivery tomorrow. Everyone's ideas on what's "safe" for a psu seem to be different and im struggling to make my mind up. I have my heart set on a corsair hx series due to reviews, past experience, 7 year warranty, and the flat black modular cables of course p). I can't decide between the hx650 (not currently at ocuk) or the hx750. Im planning to overclock to 4ghz, only have 2 hdd, 1 optical drive, 6 fans, but hopefully two 5870 down the line. Will the hx650 be enough for all this or would the two 5870 mean i should get the hx750 to be safe. Hx650 has 52A on single 12v rail. Hx750 has 60A on single 12v rail. Thanks for your replies!
