Will my PSU power this card?

post #1 of 4
Thread Starter 
Thinking about buying this GPU because it's the best bang for buck on a GTX780 with performance that I can find. http://www.newegg.ca/Product/Product.aspx?Item=N82E16814500311

However, my signature rig PSU is only 650W. Will it be enough to power this GPU, even though on the specifications page it says "700W"?

Strange that the Zotac says 700W and the EVGA Classified says 600W. http://www.newegg.ca/Product/Product.aspx?Item=N82E16814130943
Anybody know the reason being?

Thanks,
My System

its because some "crap" PSU's are in this world and would need the 700 watts PSU

in your case you will be more than fine

780's pull like 350 watts

Its propably not the best psu but more than enough. Dont worry about the watts.

My System pulls only max. 400w with fully overclock on a platinium psu as a peak. (780 + i7 3770k)
