    Psu

    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

    Re: Psu

    Esp if you want to add another later, you really want to be looking at 1kw psu
    The 3dguru review is here
    http://www.guru3d.com/article/geforc...-sli-review/14
    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.
