    Power Usage

    I currently have a Enermax Liberty 500W PSU powering the following:

    Dual Core Opteron 165 @ 2.7Ghz (no increase in voltage)
    2GB DDR RAM
    5 x 500GB HDDs
    8800GTX Graphics Card
    Audigy 2 Sound Card
    4 x 120mm Fans

    Do you guys think its alright?

    My system,

    E6550 @ 2.8GHz
    2GB DDR2
    2 250GB SATA HDDs
    DVD Writer
    3870
    3 fans and fan controller

    Draws 140W at full CPU load, adjusting for PSU efficiency thats ~120W add on 200W for the graphics card and 10-20W per HDD and your probably still less than 400W the issue is if you have enough power in the right voltages. I would think you would be fine though.

    Get a Power meter and check

    Good! I was thinking of adding a few more hard disks and wanted to make sure it will be fine

    The Enermax PSU also pumps out 22A per 12V rail, so that should be good right?

    It's not the specs that have us convinced, we just know Enermax make quality, efficient PSUs. And a good 500W power supply is enough for all but the craziest of systems.
