If you are not overclocking, go for 650W.

If you are overclocking, go for 750W.

If you plan to SLI & overclock, 1,000W.

Make sure u buy reputable brand PSU and it have enough PCI-E connections to cater ur config.

For a system using a single GeForce GTX 680 graphics card NVIDIA specifies a minimum of a 550 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 38 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors or one 6-pin and one 8-pin PCI Express supplementary power connectors depending on brand and model of the graphics card.

For a system using two GeForce GTX 680 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 750 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 53 Amps or greater and that has at least four 6-pin PCI Express supplementary power connectors or two 6-pin and two 8-pin PCI Express supplementary power connectors depending on brand and model of the graphics card.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated @ 45°C - 50°C ambient temperature, is the most important factor.

Overclocking of the CPU and/or GPU(s) will require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

Yes it is. I, myself using "TX750M" (which is semi modular version) for my rig and loving it every moment.

For semi-modular version, which means only PCI-E cables come in modular arrangement and other cables are fixed.
