I'm not enough of a PSU expert to really know, but I have to assume that with as much headroom as you will have even with two 7950s in Crossfire, this should be fine.
However, this thread would be better off in the Power Supplies forum. Can you report your original post and make a brief request to have it moved? I could do that, but it's nicer when the report comes from the Thread Starter. :)
