More about should change power
  1. These are recommeded PSU requirements for a HD5870:

    500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in dual mode)

    SO I would say yours is plenty for HD5870.
    It will run fine on your PSU.
  2. As a precaution, just check how much wattage is available on your psu's +12v rails. It should be around 45-50 A
