    Corsair.

    But do you really need that big of one?
    Kinda overkill for most everyone, unless youre running 3 GTX580s or something along that line.

    78Amps is a LOT of Power.

    Most only need 40ish & thats for high end builds, & single card setups.

    http://www.newegg.com/Product/Produc...82E16817139009 will be plenty.

    Modular version if you prefer that:

    Your call, which you prefer, but One these will be fine.

    But certainly Corsair.

    I use the corsair tx 850 (similar to the one you linked just less wattage) and no complaints here.

    IMO, you'd be better served with a "lower" 850W but higher quality Seasonic, Antec or Corsair HX than the 1KW Kingwin

    Seasonic 850W <- regarded as one of the best PSU makers, it's not pretty but it does it's job damn good too
    Corsair 850W HX

    the one stop for ALL your PSU learnings: JonnyGuru
    Kingwin Mach 1 1000W
    Antec 850W
    Corsair AX850 <- Made by.... Seasonic
    CPU: AMD FX 9370@ 5.1Ghz Cooling: Corsair H100
    Mem: 32GB GSkill 1.5V 9-9-9
    HDD: 1 OCZ SSD (boot drive), 2x OCZ SSD in Raid 0 (game drive) 1x 2TB (backup)
    GPU: Sapphire 290
    Asus VH242H (1920x1080p) X3 for 5760 x 1080 Goodness

    The Power Supply Calculators are an estimate, and sometimes just slightly exagerated. (This isnt a bad thing, just saying)

    Not all PSUs are the same.
    The major things to look at on a PSU, are not actually its wattage, but the 12V Rail amerpage, and its efficency.

    This is why some Power Supplys, such as Antec or Corsair for example, can handle the load many off brand PSUs can not, even though the offbrand may have a higher wattage rating.

    That 850W Corasir will handle SLI 570s, and have power to spare. Theres more power there than you would think. Its pushing 70Amps, and 80%+ effecient at it.

    Those links SirPent has linked can explain things better than I can.
    Its certainly worth reading through them, it will all make sense.

    Get the Corsair just for the single 12v rail. IMO but most seem to agree a single 12v rail is better.

    I had to replace a very nice 1000w PSU because it's single 12v rail @ 70A wasn't enough for 2 x 6970s (with the rest of my rig). My PC would just shut down aftef starting anything 3d. I ended up getting a Ultra X3 1600w that has a 117a 12v rail. Issue solved.
