Here a list from Nvidia site with the power supplies for SLI. You have a lot of brands , you can have from where to choose. http://www.geforce.com/Active/en_US/en_US/pdf/PSU.pdf

Budget? I suggest at least a quality 650w such as the corsair tx650w.

 

[ko888]

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 the crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important factor.

XFX 750W for a cert, that's why I bought it.

in general, real world power consumption is overestimated, use this to get a good idea of what youll need
