Best card for PSU?

If it is the Be Quiet Pure Power L7 530W, I recall reading a review on bit-tech saying that despite the PSU is rated to have a max output of 420W on the 12v rail, in their test they found that beyond around 360W on the 12v rail, the power became unstable.

So with that in mind, I wouldn't really use a graphic card that require one 6 pins one 8pins PCI-E or higher with a i5 2500K on that PSU...the max I would go for is a card that only use up to two 6pin PCI-E. A two 6pin PCI-E card with max power consumption of 225W together with a i5 2500K that consume around close to 100W when overclocked would put it at around 325W on the 12v rail, so it's leave just about enough headroom.

So what card would you recommend on that psu

Been looking for a couple of days and i havnt made my mind up yet :D
 
I think for two 7850's you would need at least 600-650w but as above 750w would be a good choice. Recommend avoiding the bequiet modular cables, they are awkward. They had to hard wire two really long fan cables to the psu for some reason as well as 4 pin power.
 
Wow, can't fault it at that price...only other one I would have considered is the XFX 650W but I also think XFX are a terrible company and won't order their products after dealing with their RMA for graphics cards.
