Recommended PSU for Haswell OC rig


Would like to buy new rig mainly for HD video editing and gaming.
Chose the following for the rig:
1. core i7-4770k - going to OC it to 4.2-4.5 Ghz with Corsair H100i LCS (and possibly de-lid it - good 'ol "hammer & vice" solution)
2. Asus Z87-Deluxe
3. Corsair 16GB DDR3 2133Mhz (OC)
4. HDD: Samsung SSD 840 Pro drive + 2TB SATA3 HDD
5. Crossfire - 2x Sapphire 7970 Vapor-X 3GB GPU cards
6. added Corsair AF/SP 120/140 case fans

Would an 850W PSU be sufficient to handle all the above or should I consider a 1050W PSU? Also, was thinking about getting Thermaltake's Tough Power PSU.

Thanks in advanced for the help :)

  1. How about a:
    Antec HCG 900 (Bronze) $124 or
    XFX P1-1050-BEFX (Gold) $140?

    850W is ok, but I'd feel safer with 900W.

    850W should be plenty. I'd suggest this:

    Seasonic made, and 80Plus is largely a gimmick. It guarantees it can meet the labeled spec, but efficiency doesn't really matter beyond that.

    The Deluxe is probably a bit of an overkill board; there's really no advantage to the high end boards.
