I currently have a Thermaltake 850 GRAND. Not sure if it can pull 2 GeForce 680+ 4Gb Video Cards (2). Just 1 card needs 38 amps from 12V rail More about : geforce 680 4gb video cards Thanatos Telos a b U Graphics card April 22, 2013 1:24:47 PM Thermaltake is an iffy brand for PSU's. Probably can, but it might die sometimes. Personally, I would grab an Antec, Corsair, XFX, or Seasonic 850w/750w and call it a day. m 0 l clutchc a c 271 U Graphics card April 22, 2013 1:29:05 PM Where did you read that each GTX 680 draws 38A. By my calculations it will draw 16.25 maxed out. (195W ÷ 12V = 16.25) http://www.hwcompare.com/12344/geforce-gtx-680/ I'd run your entire system through a PSU calculator. http://www.extreme.outervision.com/psucalculatorlite.js... m 0 l Can't find your answer ?
