  1. Because you have two graphics cards (GTX-460) I would suggest a 850 Watts PSU.

    You may get away with 750 Watts, but 850 Watts would give you peace of mind and a margin of safety. Here is a nice PSU calculator: http://www.corsair.com/learn_n_explore/?psu=yes

    Take a look at this PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139011
  2. http://www.newegg.com/Product/Product.aspx?Item=N82E16817371050
    $10 cheaper, 5 year warranty, extra 50W headroom
  3. recommend 850W or 1000W.

    you need some extra headroom.

    If it were me, i'd go with the cosair, good Watts and Amps on the +12 Rail, not to mention it's Single Rail. I <3 Single rails.
  4. A high quality 750W unit would be fine.
    A Corsair TX or HX would be ideal.
    XFX,Seasonic,and Antec also provide high quality units.

    Don't skimp out on lesser brands.
  5. I agree a 750w would be just fine for that system even with overclocking.
  6. Thank you for the help it's going to be a Corsair 850W or 1200W.
