Well If money is not an issue I would direct you to something over the 750 watt range. If you really dont want to have to worry about power anymore the ax 1200 watt would be good http://www.corsair.com/us/power-supply-units/ax-series-power-supply-units/ax1200i-digital-atx-power-supply-1200-watt-80-plus-platinum-certified-fully-modular-psu.html the ax, and hx series from corsair would be good to look around in.

For a system using a single GeForce GTX 770 graphics card NVIDIA specifies a minimum of a 600 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 42 Amps or greater and that has at least one 6-pin and one 8-pin PCI Express supplementary power connectors.

For a system using two GeForce GTX 770 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 850 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 62 Amps or greater and that has at least two 6-pin and two 8-pin PCI Express supplementary power connectors.

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 at 45°C - 50°C ambient temperature, is the most important factor.

Overclocking of the CPU and/or GPU(s) may 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.

Get a reputable brand 650 Watt or 660 Watt power supply unit if you're planning on only using one GeForce GTX 770 in your system.

Get a reputable brand 850 Watt or 860 Watt power supply unit if you're planning on using two GeForce GTX 770 in 2-way SLI mode in your system and you're not overclocking.

Get a reputable brand 1000 Watt or 1050 Watt power supply unit if you're planning on using two GeForce GTX 770 in 2-way SLI mode in your system and you will be overclocking both the CPU and GPUs.
