GTX 780 Ti 2-Way SLI Power Consumption

I was just wondering which PSU and how much watt it would take to run two 780 Tis

Think this one is alright?

  1. 850 is minimum but i suggest you to take corsair HX series .. RM series is more for mid range pc
  2. not enough power. you need about 250W for each of the gpu's and for the components to drive them i would say another 400W. 900-1000W is what you need to look for.

    Damn.

    This'll do, right?

    Also, you think this'll be fine with OC'ing?

    I'm thinking of "future-proofing" the PSU, so I'll probably get myself another 780 ti when I feel like I need it.
  4. or this:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16817139034&Tpk=Corsair%20HX1000

    with the discount price it's the same price and you get hx and 50W bonus :D

    Hi - The RM850 failed Hardocp's lab review. Corsair has since modified the unit, but I wouldn't use an RM series
    PSU until they have some good reviews.

    The problem with this is that I get a discount at the site I'm buying from, but they only got a choice between this http://www.newegg.com/Product/Product.aspx?Item=N82E16817116021 and the Corsair 1000w

    The RM series is too much of a risk, stay away.

    BTW, a good quality 850 is plenty for 2 - 780's in SLI. A good quality unit will have the +12v amps required,
    which is more important than tot watts.
