For a system using a single Radeon R7 260X graphics card AMD 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.

For a system using a single NVIDIA Reference Design 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. Some of the non-Reference Design GeForce GTX 760 cards have a single 8-pin (e.g. ASUS GTX 760 DirectCU II OC) or two 8-pin (e.g. MSI GTX 760 HAWK) or one 6-pin and one 8-pin (e.g. Gigabyte GTX 760 WindForce OC, EVGA GTX 760 SC w/ACX Cooler, MSI GTX 760 TwinFrozr Gaming) PCI Express supplementary power connectors.

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.

The Corsair CX500 (SKU# CP-9020047 / CP-9020047) power supply unit, with its maximum combined +12 Volt continuous current rating of 38 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single GeForce GTX 760 or Radeon R7 260X graphics card.
