Will this PSU be enough for this build?

So recently I've been thinking a lot about upgrading my current 2 year old setup, as it's getting quite slow at the moment.

This is the build I'm contemplating getting: http://pcpartpicker.com/user/Deoss/saved/2wf5

My current PSU is Corsair HX 650W PSU ATX 12V V2.2, 80 Plus Bronze, Modular, 4x 6+2-pin. Would this be able to run the build I want? or do I have to get a better PSU?

For a system using a single GeForce GTX 780 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. A minimum of 35 Amps or greater on the +12V rail is more realistic.

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.

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.

The Corsair Professional HX650W (CMPSU-650HX) power supply unit, with its maximum combined +12 Volt continuous current rating of 52 Amps and with four (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single GeForce GTX 780 graphics card.
