I'd go with a 600W so perhaps this one

I've used this calculator: http://www.extreme.outervision.com/psucalculator.jsp

 

Pretty pessimistic calculation, but I'd suggest an at least 500w PSU.

I would probably go for a 750w PSU, this will give you a bit of flexibility for the future.

You never know when NVIDIA will reduce prices....so you can add another 970 down the line.

I would reccomend http://www.overclockers.co.uk/showproduct.php?prodid=CA-023-SF&groupid=701&catid=123&subcat=2466 - Superflower 750W psu.

You may not have heard of the brand, but these are the same rebranded PSU's which evga and corsair use.

Superflower are not readily available in North America so depending on the users location it might not be an option. 

 

Also Superflower don't make psu's for Corsair. They mainly use Chicony Power, Channel Well Tech and Great Wall. The higher end stuff uses Seasonic and Flextronics.
