That unit has 2 12 volt rails each puts out 18 amps for a combined 32 Amps it is one of cooler master's better PSU but I cant find a price for it and it probably isnt worth what they want for it. That unit should be able to power those cards but it will be cutting it close.
I would go with a Corsair or Antec
Antec 500 watt PSU http://www.newegg.com/Product/Product.aspx?Item=N82E16817371035
Corsair 550 watthttp://www.newegg.com/Product/Product.aspx?Item=N82E16817139004
Either unit will power those cards just fine.
AMD Recommends 600 watt PSU but a quality 500 watt PSU will be more then enough to run it I wouldnt recommend getting that unit.
