Power Supply query

[theeighthbyte]

Specs:

AMD FX-6100 @ 3.9GHz
1x Sapphire Radeon HD 7850 OC @ 920MHz
8GB Corsair Vengeance RAM @ 1600MHz

What power supply would be recommended for a PC of this spec?

a 500W PSU will be just fine (dont make it a "3$" PSU 😛 )

this could easily be run on a 450-500 watt PSU, a cx430 or cx500 would be a good choice if on a budget, otherwise maybe a seasonic or higher trim corsair. I'm not sure what else you have on your build, but this can give you a good idea of your ballpart after you put it all in:

AMD says a 500W PSU or greater for the GPU.

I'd get a 600W Corsair to allow for expandability down the road.

For a system using a single AMD reference design Radeon HD 7850 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 27 Amps or greater and have at least one 6-pin PCI Express supplementary power connector. Some of the non-reference design Radeon HD 7850 graphics cards require at least two 6-pin 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) 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.

May I suggest the Corsair 600W CXM Builder Modular PSU? ( http://www.ebuyer.com/429985-corsair-cx-series-cx600m-atx-power-supply-cp-9020060-uk?utm_source=google&utm_medium=products&gclid=CKudpIb2jLkCFYfMtAodqmwAvQ )
It's modular, so it'll help keep your case tidier, allowing better air-flow. It's also a 80 plus bronze PSU so it's pretty efficient.
