I have a questions on how much watts I may need

I have a 8800gtx. I was wondering if 600 watts is good enought for this card and an amd phenom II 965 black edition.

Thanks for you time

If the 600w has 25A+ on the 12v rail you should be fine. You could get away with a good 550w psu too http://www.newegg.com/Product/Product.aspx?Item=N82E16817371016&cm_re=550w_psu-_-17-371-016-_-Product

This is what I have http://www.case-mod.com/thermaltake-w0129ru-purepower-600w-atx-12v-20-power-supply-with-active-pfc-black-p-3349.htmlto what you have told me it should work. Thanks
