  1. Your CF 7870 cards will need about 600w.
    From that point of view, you are ok.
    But, the CX corsair series are only tier 3 on this list. Not bad, but not the best either.

    I might look at something in tier 2
  2. so would this be better? as still just within price range XFX P1-850S-NLB9 PRO850W Core Edition Power Supply

    That would be much better.
    XFX is made by Seasonic.
    I like to overprovision a bit; the psu will consume only the wattage that is demanded of it.
  4. You could save some money with this, and enough for your entire system :
