You will need about 700W9almost 60A) on the 12v rails! What display/resolution are you using?

Umm, why? Not that tri-SLi is the best investment, but upgrading from a 9650 to i7 isnt much smarter in my book. xema25 January 13, 2009 3:18:04 PM rangersig said:with the money you would spend on another gtx280 and a high end power supply you could futureproof even more by upgrading to a core i7 system. Im using 1900x1200, at nvidia slizone web they say that for trisli I need minimum 1000W or 1200W (it deppends on the model of the PSU) I think mine is fine. Im upgrading because now GTX280 are cheapper and they will disappear (as every product of nvidia that has more than 3 months lol) What do you think about my PSU :S? THANKS ! Can't find your answer ?
