Psu for sli 560 ti
will a cooler master 1000 watt psu be enough for an sli'd EVGA 560 ti FPB ?
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
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.
Exactly why i said he should get the XFX unit as it has single rail technology so all its AMPS on the one rail.
