PSU for gaming pc Tags: Power Supplies Gaming Graphics Cards Components Last response: December 5, 2012 9:17 PM in Components Share BMF96 December 5, 2012 9:10:59 PM This is my current build http://pcpartpicker.com/p/r4Mf Everything has been ordered except the video card and the PSU. I am most likely going to get a radeon 7950 (possibly 7970) and may crossfire it eventually but not soon. How many watts do I need and could you recommend one? More about : psu gaming payturr a b ) Power supply December 5, 2012 9:13:53 PM I say 750W. I personally do not own a custom PC (yet) but I know numbers enough to say 550 isn't enough to power all that + 2 GPUs. I say at least 650, but 700-750 is a good spot. EDIT: Also, go with Corsair, I've seen many good PSUs from them and I plan to use one in my own rig once I have the money for it. m 0 l toyftw a c 281 ) Power supply a b 4 Gaming a c 113 U Graphics card December 5, 2012 9:17:08 PM BMF96 said:This is my current build http://pcpartpicker.com/p/r4Mf Everything has been ordered except the video card and the PSU.

Hi - There's quite a big diff in power consumption between these 2 cards: 7950 - Avg game power usage = 288w & up tot sys 7970 - Avg game power usage = 352w & up tot sys So, If you're going with 2 7950's then you need a quality 650w unit and 2 7970's would require 750 or more w remember - you need a psu with 4 pci-e connectors m 0 l Can't find your answer ?
