Plenty of decent stuff available for £30 as linky and Scan shows ^^ Will leave other reccomandations to the experts, but they will ask what make/model is your current PSU as if its decent you'll be surprised what it'll power, all about amps on the 12v rail and quality of the guts... Have you tried it with the 2900XT yet?
