HD 2900 Pro draws up to 12.5 amps on the +12V rail. Any power supply with at least 30 amps on the +12V rail should be able to power it all day long, even this one:

This is currently the cheapest PSU I would buy that will power any single video card system for $65 shipped:

80+ efficiency (higher = less electricity turned into heat)
33 amps on a single +12v rail
450watts
