A question about power supply, and if I would need more power.
Hello, I have just ordered my gaming computer ( http://www.newegg.ca/Product/Product.aspx?Item=N82E16883229420 ) and this model comes with a 800W Power Supply. Now if I wanted to upgrade the graphics card to lets say 2-way sli gtx 670's instead of just the one that comes with it, would I need to also up the supply? or is 800W sufficient?
The 800 watts PSU will be adequate if it is a good quality PSU; Corsair, Antec, XFX, Seasonic, or equal.
The GTX 670 draws 170 watts and requires a PSU which has a minimum of 30 A on the 12V rail - http://www.evga.com/Products/Product.aspx?pn=04G-P4-3671-KR
