The motherboard supports crossfire. I would need to know the make and model of the PSU to tell you if its good or not.

Corsair makes several models, the VS, CX, RM, TX, CS, HX, and AX. Some are really good units and other have issues. For example a 750w CX(budget units) would run that rig with 2 r9 270, but the cheaper capacitors used in their construction have a high failure rate especially when under heavy loads or when hot.. On the other hand a 750w HX doesn't have this problem.
