More about rails
  1. 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

    Corsair 550 watt
    http://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.
  2. I only want psu fr one 5750
  3. I purchased a Cooler Master Extreme Power Plus 600 Watt for less then most 500-550 Watt power supplies and it has 2 +12V rails @ 18 Amps and supports 2 - HD 5770, so either one of the PSU listed by Saaiello would be good. Antec Basiq 500 Watt is cheap and will do the job fine!
