What power a gtx 780 actually needs?

[frenzy1]

Hey, i am going to upgrade my old gtx 570 to 780, and by pc has a 600w power supply, im wondering if i am going to buy the 700-750w.

The question being, do i really need 700^? Or can i spare a few bucks by keeping the 600w one?

Depends on what quality the power supply you are getting. A Seasonic 650W will be fine.

This EVGA PSU will work fine too http://pcpartpicker.com/part/evga-power-supply-120g10650xr

Basically, you're much better off with a high quality 650W PSU than cheaping out on a low quality 750w PSU.

And yes, both the EVGA and Seasonic PSUs are of extremely high quality and should both work fine

A GeForce GTX 780 needs 42 amps on the 12v rail and a 600 watt power supply.

That EVGA power supply isn't a good one the B2 , or G2 series is the good one.

My bad! Go for the seasonic G-series or EVGA G2/B2 as SR-71 said
