Corsair TX-650 enough for crossfire/sli?

I have a corsair TX-650 , with 52 amps on a single 12volt rail,

Would I be able to power two 6850's in crossfire with overclocking? (so essentially two 6870s)

Or from the green team would I be able to power two gtx 560 ti's in SLI with overclocking?

Note I also plan to overclock my cpu to around 4ghz

System specs:
i5-2500k
Asus P8P67 pro
Antec 300 (2 stock fans only)
8gb (2x4gb 1600mhz ddr3 ram)
1 HDD (WD caviar black)


Thank you....

More about corsair crossfire
  1. easily, during gaming total system power won't break 450w
    CPU: Intel Core i7-920 @ 3.33GHz
    Motherboard: Asus Rampage II Extreme
    Chipset Drivers: Intel 9.1.1.1015 (Intel)
    Hard Disk: OCZ Summit (120GB)
    Memory: Patriot Viper DDR3-1333 3 x 2GB (7-7-7-20)

  2. Agree with ct1615.

    Used this to help figure it out: Antec Power Supply Calculator Used 80 percent utilization, 25 percent capacitor aging, 4 led fans, plus the specs you provided.

    Came up with 515W for the OC'd 6850 and 562W for the 560Ti cards.
  3. Be sure to get the tx v2
  4. Thanks for the replies, ill probably play it safe and go with two 6850s then since ati seems to use less power. I dont even need the 560ti's anyways... its just that I found the msi hawk one on kijiji for $200... in Canada so its a good price, but somebody beat me to it unfortunately.

    What is the difference in the V2? I bought mine a while ago so its V1.
    Is there anything in particular wrong with the V1? lol ... now I am worried...

    There's nothing wrong with a TX650 V1 !
    No worries:)
  6. If you already got the v1 there isn't a problem.but if you buying one now the v2 is the one to go for
