I have a 80plus 500W PSU. I don't know if its a Generic PSU. Here its specs.

+5V 25A
+3.3V 25A
+12V1 15A
+12V2 18A

Will this PSU be able to run a 9500GT/9600GT/9800GT card with my specs.

640GB Western Digital SATA 16mb

  1. The answer to your question is yes, it should be able to run one of any of those GPUs. For SLI buy a better power supply.
    The 80 Plus certification makes me think your 500W unit is at least decent.
  2. Best answer
    If it is a 80 plus certified PSU it will easily run a 9800GT.
  3. As shubham said, if it is 80+ it should have no problem. The 80+ program uses a lower than typical ambient temperature for testing, but does run the PSU long enough to get warm. One of the problems with generic PSUs is they often aren't good for the output claimed on their labels. To pass the 80+ test requires that a PSU output 100% of its labeled rating, and do so efficiently. You should be fine.
  4. Thanks !!
  5. Those cards will run even if your PSU was a 460watt 80plus. What brand or manufacturer is that PSU from anyway?
  6. Its a iMaster Pro 500w.

    I googled it but I didn't get any good info about the brand and PSU. So I just assume that its a generic PSU.
