Psu and crossfire

Hi all,
I'm about to install my second 6870 into my rig, only problem i have is that i didn't really think about if my psu would handle it (stupid i know)
Rigs in my sig, my psu is this:

Any ideas guys before i try?

Thanks

Thanks for the reply RJC, i'll give it a try and see what happens i guess, hopefully it'll be fine, if not it's time for new psu.
