  1. yes, although I suggest going with a different brand such as Antec, Corsair, or Seasonic. Cooler Master PSU's do not have the best reputation.
  2. Actually, Cooler Master PSU's are fine as long as you stay away from the Extreme Power series.

    @ pablopicasso: I'd look at the Antec HCG 620, Corsair GS700, Corsair TX650 or Cooler Master GX650/750, depending on the rest of your build.

    For most part, a 650W/700W PSU will be more than enough to handle a general build with two 560Ti's. 1000W is completely overkill, you can run 3 GTX560Ti's with add-ons and overclocks with 1000W, without even coming close to it's limit.

    If i was you id get yourself this unit from XFX, in my opinion they are the best value for money/quality PSUs you can buy at the moment, and this modular 850w single rail unit will leave you with a nice amount of headroom for your system

  4. ^+1 for XFX but CM silent pro series is good IMO.i have a 1kw 80+GOLD and it's working well for me.
  5. For a system using two GeForce GTX 560 Ti graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 700 Watt or greater power supply that has a combined +12 Volt continuous current rating of 52 Amps or greater and that has at least four 6-pin PCI Express supplementary power connectors.

    Total Power Supply Wattage is NOT a crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important.

    You would be better off getting a high quality 750 Watt PSU than wasting money on a mediocre or low quality 1000 Watt PSU.
  6. Exactly why i said he should get the XFX unit as it has single rail technology so all its AMPS on the one rail.

  7. A properly designed multi-rail PSU will work just fine.

    I recommend that you avoid it if you value system stability.
  10. Oh gosh those extreme psu's :non:
