    Minimum 450W or greater system power supply (with 12V current rating of 30A)

    How many amps do you have on the 12volt rails?

    Then call your friend and ask him exactly which namebrand and model number it is.
  4. Im pushing a EVGA 8800 GTX with a Antec True Power II 550. 2 12v rails @ 19A each.

    My system under a full load is 352 Watts, leaving about 198 Watts to spare for whatever.
  5. how do you calculate the max PSU load in a machine ?????
  6. Power Supply Calculator v2.0
    Its more important that you know the AMPS available on the 12volt rails than the total wattage for the PSU. A 500w PSU might not have 28amps on the 12 volt rails.
  7. I cheated using my APC battery backup w/ Power Chute software. It can tell you your system load. 352 Watts is a little high because I have my LCD hooked up to it. None the less, it still leaves some room for another hard drive ect.

    i am guessing that the PSU has these ratings on them ??
    and thanx for the link
  9. Usually... but not always.
    If the make and model are known we can usually look up the actual specs on the 'Net.
  10. thanx again
