GTX 560 ti Sli with 600w PSU??

Hi All,

I have a system i buit recently and not considering future upgrades I only fot a OCZ Modstream Pro 600W Modular PSU.
I have a Gigabyte GTX 560 ti and want to get another for sli.
Is my PSU sufficient enought to power both cards??
Btw.......my i5 2500k is overclocked to run at 4.2GHz.

Thanks for your imput!!!

More about 600w
  1. You won't have enough connectors to power 2 GTX 560 ti's, they both require 2x 6-pin connectors, and that PSU only has 1x 6-pin and 1x 6+2-pin.
  2. It would be close but it will not be enough especially with the overclock on the cpu.
  3. Your PSU isnt powerfull enough for those cards and also lacks the connectors needed to power them.
  4. Hi,
    I have extra six pin connectors that i have spare if that helps. If 600w is not enough what would be sufficient??
    Many thanks

  6. A good 700W PSU would suffice, although I recommend at least a good 750W since you do some OC.

    Look here for a complete list of PSU for SLI configurations:

  7. You could probably get away with a 650W PSU, but a 750W would allow you more overhead in case you upgrade later.

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817151087 is probably one of the best 750W PSUs out there, 80Plus Gold, full modular, and has a 5 year warranty.
