I think he wants to do 3 GTX SLI not GX2

And yes your psu will be fine, although I'm not sure if it will have enough pci cables.

Might need to buy another PSU just for the cables.

He said GTX and yes he can

and no the power supply is insufficient

I would recommend a decent 1000w power supply

silverstone for example

Going for quite the benchmarking machine over there.

I'd go for a 1000w PSU.

A loaded rig with one 9800GTX require 450W, max power draw for one 9800GTX is 168W so 2x GTX is 340W. The total is around 800W. So, you toughpower 850w should make the cut.

that psu is fine, since they should use less power then the 8800gtx (being g92).

Thanks guys what i might do is try my psu first i have got 4 proper 6 pin pci express rails and i will have to get 2 molex to 6 pin converters . that way i will have all 6 that i will need . But if i start getting problems i know the first port of call will be the psu . i also thought a 1000w might be the way too go.
