I am planning on upgrading my gpu from a 6670 to a 7850 or 7870. I have a 500w corsair psu with a 6 pin connector. Will the card work with my psu? I looked on amd's website and they say the minimum needed is 500w. My other specifications are the amd fx 6300 @ 3.5ghz, 6670 2gb ddr3 and 16gb ram. Is 500w enough to power the 7850 or 7870?

500w is enough for those cards but you need the appropriate amount of amperage as well. Can you tell us the make and model of you psu?

It's probably the CX500.

See this is the thing i don't really know the exact name of my psu i have looked at my pc where i bought it from but i cant find a psu brand name on their. Is there anyway checking exactly? If not heres the products website. http://www.ebay.co.uk/itm/Mars-B-AMD-FX-Six-Core-4-1Ghz...

Well apparently I can't read because I didn't see that you said it was a corsair psu.

Blackbird is most likely correct. CX series is their lowest end psu that corsair sells and even those have plenty of amperage(38A, required for those cards is 21A). CX aren't the best but it'll be able to run a 7850 or 7870.

Here's what I used for graphics card power recommendations for systems

EDIT: that link makes no mention of the brand of the psu. You could always open up your case and look....

For a system using a single AMD reference design Radeon HD 7870 GHz Edition 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 28 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.

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.

For a system using a single Radeon HD 6670 graphics card AMD specifies a minimum of a 400 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 20 Amps or greater.

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 Corsair CX500 (SKU# 75-001667 / 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 Radeon HD 7870 GHz Edition or a single Radeon HD 7850 or a single Radeon HD 6670 graphics card.

The only other 500W Corsair PSU is the GS500 but that model has been discontinued.
