Solved What size of PSU do I need? Tags: New Build Systems Last response: June 30, 2012 7:49 AM in Systems Share Brmiller13 June 30, 2012 6:44:06 AM Hello, I am planning out my new Desktop build, and am wondering what size of PSU I would need. My specs so far are: Case - Cooler Master Haf XM CPU - Intel 3570k Ivy Bridge GPU - Radeon 7950 Hard Drive - Western Digital Caviar Black 1TB RAM - Corsair 8 (or maybe 12) gb Vengance Motherboard - ASUS Sabertooth Z77 CPU Cooler - Cooler Master V8 Not sure what PSU would be adequate for this build. I am planning on doing small overclocking, nothing serious. Thank you!

Also if this is a gaming rig 8gb is plenty. Can't find your answer ? Ask ! Publish Related resources: ForumWhat size PSU will I need for this build? ForumWhat PSU size do I need ?
