power needed for this system

[beasty6]

hey guys,

im in progress of building myself a pretty powerful gaming rig and i would like to get some advice and thoughts on how much power this system is going to need and a good psu to handle it

so the system spec

i5 760 (OC to 4GHZ)
4x2GB corsair xms3 1600mhz
msi p55 GD80 mobo
msi gtx 460 hawk talon attack in SLI (maybe gtx 470's)
coolermaster 430 elite case
corsair h50
4 120mm blue LED fans
1 140mm blue LED fan
2 samsung F3 1TB HDD's
CD/DVD drive

now i know thats going to draw some power from the wall but i dont want to go buy a psu then find out that its not going to give enough power

also a modular psu would be peferrd but a normal psu will do as long as it has long cables and will be easy to organise behind the mobo tray

cheers guys and a happy new year

750 would be fine.

this is what gets me confused,

some people recommend 650 then some at 750

i want some head room as well for future upgrades

Link below shows power usage for the range of GPU'S:

650W will run 460 in SLI.

The one in said, I have and me and you have the same set up but different gfx. One thing you don't want to do is skimp on the psu.

 

[beasty6]

RJC, is that with head room as well for future upgrades or is that stressing the psu ???

That will give you some future upgrades.
