    I just got a used Mac Pro 2009 with dual 6 core Xeon 3.33ghz
    Total 12 cores.
    Idiling it is using about 11 amps or about 1265 watts. No open apps.

    I bought it to run [redacted] with 24 1080p security cameras.
    When [redacted] is running, it is up to 24 amps or 2760 watts.

    I know how to use an ammeter and it the results are pretty clear.

    I thought the power supply was only rated for a max of 980 watts.

    My central AC uses this type of power consumption.

    I tried two different ammeters to test and got the same result.

    Anybody know if this is normal?

    Did you see if the vents are clear from dust?
