What Budget do you have?

AMD offically recommends at least a 650w PSU to run the card, the reference design cards need 1x6pin and 1x8pin connectors. http://ati.amd.com/products/certifie...rsupplies.html

Corsairs PSU finder recommends a HX620 or above to run a heavily overclocked setup. http://www.corsair.com/

I'd imagine a corsair 650tx would run that setup nicely.

I agree - a good branded 620 - 650ish watt PSU should be good

[rover214]

the TX650 is a good psu but, gets noisy after you start to ramp the wattage used up

Take a look at the OCZ 600w ModxStream for around £65, Modular, efficient and if you are only having the one gfx card in your puter then, it's excellent

just my experience working with these psu's

I ran a setup almost identical to that, the Q6600 was at 3.4Ghz and 1.5V. I ran it all off a Corsair HX 520W, no complaints at all from the unit. Power draw at a.c. was about 450W max load, factoring in efficiency loss that works out about 380-390W max from the unit itself.

Anything from a decent brand between 550-650W would be fine, Corsair, Be Quiet, enermax, OCZ ModXtreme etc will all do you fine, whichever you can get the best price on.

Just wanted to add Seasonic, Antec and PC P&C to that list
