How much power should I use for Dual 8800 gts?

[Swimdude776]

I am building a system this week.

I have th Nvidia 590 or 690 Sli i forget.

AMD fx-62 Dual Proccessor.

a dvd drive.

and i have one 8800 GTS. I want to eventually get another.

I bought a 750 watt thermotake power supply today. Do you think thats enough?

thanks guys

Next generation four +12V rails(12V1, 12V2, 12V3, 12V4) supports high-end graphic card and PC system (combined loading of 60A)

anyone help?

should be fine but if you change to gtx or add anything else power hungry you might need to get a new one from 850+ with 60+ amps

yeah that will def run it most likly but tell us your amps, although i am 99% it will work as my 700watt ocz gamestream will run 2 in sli

 

[hermeslyre]

He already posted the Amps..

That's a nice PSU, it will no doubt be able to handle all that plus SLI'ed 8800's.

That PSU is quite sufficient for the system in question.

Hold on you will almost need a 1.000 WaTT or 900WATT

A single requires a 450WATT Double it 900WATT.!

When they say "450w" they are bringing the entire system into the equation.. surely you don't have to double that just to stick an extra GFX card in
