System Power Supply Requirements for a single GeForce GTX 960
• NVIDIA specifies a minimum of a 400 Watt or greater system power supply. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.)
• the system power supply must also have a maximum combined +12 Volt continuous current rating of 28 Amps or greater
• the system power supply should also have at least one 75-Watt 6-pin PCI Express supplementary power connector. There are some non-reference design cards that require two 75 Watt 6-pin PCI Express supplementary power connectors...

I like to use newegg for computer parts shopping and once I have found the part, I then check if amazon has it cheaper. there are other sites too, but they do not always seem to have the lowest prices around. I have had nothing but success from EVGA power supplies and Corsiar makes good ones too. while you really only need about a 550 watt PSU, I would get a 650 watt PSU for future upgrades.
here are some PSUs that look like good candidates

• the system power supply should also have at least one 75-Watt 6-pin PCI Express supplementary power connector. There are some non-reference design cards that require two 75 Watt 6-pin PCI Express supplementary power connectors (e.g. Gigabyte GTX 960 G1 Gaming 2 GB [GV-N960G1 GAMING-2GD REV.1.0], Inno3D iChill Geforce GTX 960 2GB Ultra) or one 150-Watt 8-pin PCI Express supplementary power connector (e.g. EVGA GTX 960 SSC 2 GB [02G-P4-2966-KR], MSI GTX 960 Gaming OC 2 GB [GTX 960 GAMING 2G]).

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) 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.
