Default 2x HD4870 - 750w?
i only have around 90 pounds to spend on my power supply and it needs to be able to do crossfire for atleast 2 ati 4870's.... do you think a corsair 750w power supply would be sufficient as it fits into my price range and is apparently good

here is the components i am about to order tonight, suggestions please?

One 4870 is 150w. The corsair 750tx should be able to handle 4870CF.

System requirements say you only need a 600w. A good 750w should be more than fine.

The corsair will be plenty, anyone who will tell you otherwise is ill informed.

the corsair 750w power supply has 4 pic-e 8/6 pin connections, so he'll be fine
