    SeaSonic M12II Bronze 620W 80 PLUS PSU

    Fine for your setup and a little overclocking.

    Modular also to keep your build neat.
  8. For a system using a single GIGABYTE GV-R785OC-2GD graphics card GIGABYTE specifies a minimum of a 500 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 26 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

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

    The two PSUs mentioned by @SR-71 Blackbird are way more than sufficient to power you system configuration with more than ample spare capacity to handle any overclocking of the CPU and GPU.
