I'd go 600 minimum..
Why? What if you decide to crossfire in a year or so or add peripherals?
Also you're pushing it close and the psu is going to stress out because of it.
A higher end psu would have better components and be more capable of taking that beating with more headroom.
Run a "almost strong enough psu" and you could find yourself in an issue where your games start randomly crashing and getting weird corruptions. Or worse, you could fry your entire system..

At least get the 550.. minimum imo..
