Hmmm, the link says the item was deactivated, then showed a list of Coolmax products. If it was a Coolmax PSU, it was probably junk; "max" in the name of a PSU seems to refer to the amount of smoke and sparks it will emit when used to power a PC, or the number of components it will take with it when it dies.
Look for something around 550W-650W from Antec, PC Power & Cooling, Corsair, or Seasonic. Make sure the new PSU will fit; once you get to that wattage, the PSUs are often a little deeper than "standard."
