I'm fond of Cooler Master,
[ame="http://www.amazon.com/Silent-Pro-800W-Modular-Psu/dp/B003O8J12S/ref=sr_1_2?ie=UTF8&qid=1301528269&sr=8-2"]Amazon.com: Cooler Master Silent Pro Gold (SPG) 800 Watts Modular Power Supply: Electronics[/ame]

Would that be okay?

Mine run fine on my Corsair 850TX. They might even work on a 750TX, got the 850w just to be sure, though.

A 6970 draws like 21 amps @12V I think. Make sure the PSU has a good reputation, and that it can provide enough power to the 12V rails.

Im not a fan of coolermaster my self, but they have steped up their game on the Pro Gold series.

What about this. http://www.scan.co.uk/products/750w-psu-corsair-hx-cmpsu-750hxuk-modular-90-eff-80-plus-silver-sli-crossfire-eps-12v-fan-atx-v291

You can even get the HX850 for the same price as the CM http://www.scan.co.uk/products/850w-psu-corsair-hx-cmpsu-850hxuk-modular-90-eff-80-plus-silver-sli-crossfire-eps-12v-fan-atx-v291

Any solid 750W PSU will be fine. (By solid, I'm more inclined towards Corsair, Antec and Seasonic. XFX and Thermaltake aren't bad either ).

Thanks. I'll probably end up going with the 800w cooler master; maybe the Corsair's if they're cheaper at the time.

I would, but those prices are in euros I believe; so it'd end up costing more.

It's 171 dollars if I were to buy that, others are cheaper. I don't exactly have money burning through my pockets. tongue.gif
