Psu

[smokeygt4]

I am thinking of gretting 800w psu I will be running x2 videocards and maybe more later, would 800watt be enough and also I was thinking to get the brand "Corsair" Gaming Series GS 800 CMPSU-800G UK 800W.

Video cards will be GTX 580.

Thanks

hmm that will be one hell of a rig,
i wouldn't use a 800w, you are better off getting a PSU closer to 1KW

the test system on Guru3D with gtx 580 in SLI is using 719W of full load

Esp if you want to add another later, you really want to be looking at 1kw psu
The 3dguru review is here

They where using an overclocked i7 965 which is one of the highest power consuming cpu, so a cpu with lower power consumption could knock a chunk off that total.
Still the two gtx 580 in sli used 522watt between them so you'd still want a 1kw watt psu if you want to consider adding a third.
