Get a Corsair gold+ You wont regret it. Unfortunately I had to learn the hard way your PSU is THE MOST IMPORTANT thing no one thinks about and they keep shelling out more and more money on cheapy ones that keep breaking. Go big or go home. Im running a corsair pro 650w gold+ with crossfire 3 HDDs 1 SDD and 24 GB of vengeance ram. with the new i7 unlocked haswell. Barely a burp from it.
