For a system using a single GeForce GTX 760 graphics card NVIDIA specifies a minimum of a 500 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 30 Amps or greater and that has at least two 6-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.

The OCZ CoreXStream 500W (OCZ-CXS500W) power supply, with its maximum combined +12 Volt continuous current rating of 37 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is sufficient to power your system configuration with a single GeForce GTX 760 graphics card.

Not a good power supply unit though. It has borderline ripple suppression, poor efficiency and borderline voltage regulation. The OEM is actually HEC Group.

You can see KitGuru's review of that power supply here:

It has enough +12v amps and the required 2 pcie connectors, so
it'll run that system.

You might want to start planning on upgrading the PSU tho, as Blackbird
mentioned, some OCZ units aren't that great. And that one being
mfd by HEC is cause for concern.
