  • Question

  • Anyone have a very baseline figure on how much power a harddrive needs? I currently have 6 drives (all sata) and was thinking about adding a couple more ATA but don't want to get into a power situation. Anyone got some numbers so I can know if my power supply will handle more drives? Thx!

  • I know that my P4D CPU, mb with integrated video, 2gb ram, DVD, and 20 Sata drives (I'm not using all 20 right now, but planned for it) would run on a 750watt PSU.

     

    There are quite a few PSU Calculators out on the net, any should give you decent numbers for planning purposes.

  • You should get the datasheets for the particular drives you are using. Most desktop SATA2 drives at 7200 RPM draw 8-10 watts when in use.

  • I have the following running on 400w, APC UPS say's I am drawing 230~260w with all drives running and router+switch+17" screen running.

     

    Athlon 3200+

    512mb + 256Mb ram

    Nvidia Quadro 64mb Video (AGP)

    Highpoint 404 Rocketraid Card (PCI)

    1 x 500gb ide

    3 x 400gb ide

    1 x 123gb ide

    5 x 120gb ide

    1 x DVD ide

    3 x 120mm fans.

     

    No problems at all. I plan on replacing the 120gb disks over a period of time with 400gb or larger, I don't think you will have any trouble.
