It will not kill it, but I'd start with 800 watts or more for something somewhat high like the HD5770.

You should be fine, since you're not OCing, but it is a bit close to the PSUs full load.

The Extreme-power series weren't great PSUs to start with, and you'll be pulling about 550W on full load out of the 624W it has.

Also, it only has max output of 52A on the +12V rails, 25A on +5V, and 25A on +3.3V.
It only has amps equal to a 624W PSU.
I should prolly get a corsair 850W? They seem to provide adequate amps on the rails?

I really wouldn't risk it with 52amps.

I've seen benchmarks that show a system with two 5870s draw around 550w+ with everything at stock settings, and 650w+ with some overclocking.

I would get the corsair 850w, it's a great PSU with around 70amps on a single 12v rail.
