Closed Upgrading to GTX 670; PSU question. Tags: Graphics Cards Gtx Asus Power Supplies Graphics Last response: August 1, 2012 3:30 PM in Graphics & Displays Share Enjoi July 31, 2012 8:59:37 PM Hello, I'm swapping out my 4850 and I'm wondering if my 750 PSU will be enough for the GTX 670. The reason I ask is because ASUS's power supply calculator leads me to believe I will need a 900+ PSU.

The GTX 670 requires 173W at max load. That translates into 14.4A on the +12V rail. http://forums.atomicmpc.com.au/index.php?showtopic=264 Unless your 750W PSU is a real cheapie, it should be more than enough. You might want to run the numbers thru a different calculator like this one: http://www.thermaltake.outervision.com/ I don't know how you could have come up with a 900W+ result unless you entered something wrong.
