Hiya all, I have future plans (if I ever get a job :(  _) of getting another 560 ti and hooking up my rig with SLI, my question is what would be the best PSU to purchase (if I even need to purchase one) for my system and thinking of future upgrade headroom.

Here is my rig right now:

Case: Haf 912
Mobo: Asus p67 Extreme 4!
Cpu: 1155 I5-2500k
Memory: 2x4gb corsair vengeance
HDD: 1 7200 rpm 1tb black caviar wd
SSD: 1 64 gb m4
Fans: 6 (4 high power)
PSU: XFX 650 W 80-plus bronze

That's about all the relevant data I can think of for now, but let me know if you need anything else and thanks in advance for helping me out!

For a system using a single GeForce GTX 560 Ti graphics card NVIDIA specifies a minimum of a 500 Watt or greater power supply that has a combined +12 Volt continuous current rating of 30 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

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.

The XFX ProSeries 650W Core Edition Full Wired (Bronze) (P1-650S-NLB9), with its combined +12 Volt continuous current rating of 53 Amps and with two 6-pin and two (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single GeForce GTX 560 Ti and adequate for two GeForce GTX 560 Ti in 2-way SLI mode.

The Corsair Professional Series Gold AX750 (CMPSU-750AX), with its combined +12 Volt continuous current rating of 62 Amps and with four (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with two GeForce GTX 560 Ti in 2-way SLI mode and have spare capacity to handle overclocking of your CPU.
