Should have no issues but i would still recommend a higher wattage PSU for a crossfire setup like that to be safe.

That PSU will probably work for a 7870 crossfire setup but it will be pushing it to it's limit i would recommend atleast 750-800w to allow room for your other components and give you the power for overclocking if you choose to do that.

it is always recommended that you have 20% more power than you need for example i have a 950w psu as i run a i7 gtx 780 and a ati 7770 ghz ed and that works completely fine and still allows room for overclocking which again i wouldnt recommend unless you know exactly what your doing.
