More about what 5970
  1. Hello, im ordering a new build with ATI 5970, ASUS rampage 3 and i7 930. Im using it mainly for playing but i will do some little overclocking too. Will Corsair 850HX ATX2.3 be fine or do i need 950 or 1000HX PSU?

    850X will be more than enough- that is what I'm currently running on my same setup (i7-930, 5970). No power problems whatsoever. Even room to upgrade!
  3. 850 is way overkill but a safe point.

    On a search it said a 5970 is up par with a pair of 5850 in power requirements so roughly 600w. Given a little safety room 700w would suffice but 850 is certainly some sort of happy medium.

    ATI 5970 - 294 Watt
    i7 - 930 - 130 Watt

    850w is too much...You can go with 750-800W



    Overclocking room + room to expand/upgrade in the future is worth the extra $20 going from a 750->850.

  6. A quality 850 watter will be more than enough for one 5970....although ATI says it's fine for two, I'd go bigger if you think you will ever get a 2nd 5970 and overclock to any significant level.
