    5870 XFIRE PSU

    Hello all
    im currently using a corsair tx750 watt psu, to run spec in sig
    the quad is clocked at 4.0
    what i would like to know is, would i be able to add another 5870 and run xfir with this psu ?
    if it makes any difference ive also ran a gtx295 with same spec minus the 5870 obviously
    many thanks

    yes that psu is fine. if you want to be on the safe side though you could up to an 850, 900, or 1000W but like I said you are fine with that psu

    You will be fine with that PSU.

    I think the TX750 is actually a 900-950W PSU. I read a review somewhere and they tested it and they managed to draw way more than 750W without any repercussions. So you're all good!

    The corsair series of PSUs are very solid and well done. They are all rated at a lower Wattage than they are capable of.

    I wouldnt say that for all. I know the HX620 was supposedly under rated, but otherwise, respectable review sites just have it pegged as a top notch unit in ripple/noise etc. I certainly wouldnt be comfortable stating that as its written. They can output what they say they can output even in a hot box.
