PSU: 700w enough?

ITR521 · Oct 15, 2013

I'm getting a 7950.. is a 700w PSU enough? I'm also getting an FX 8320. Thanks

only if it has some sort of certification

For a system using a single AMD reference design Radeon HD 7950 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 30 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors. Some of the non-reference design cards require one 6-pin and one 8-pin or two 8-pin PCI-E 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) 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 PSU does have 12V and 2x 6-pin connector. The only thing is my GPU is non reference

What is the brand and model of your Radeon HD 7950 graphics card?

I should have also asked you what the brand and model of your PSU is since the +12V continuous current rating will determine whether or not it's sufficient.

Sure, Thermaltake TR-700 700watt ATX PSU

Yes. It should definitely be sufficient.
