Hi there,

I am just surprised this machine I got from a refurbished sale has quite high power draw. Even when I remove all of the peripheral parts and just leave one CPU in the chassis, so remaining just:

- 1x Xeon Gold 6132 (14c/2.6 GHz, 140W TDP), 2x 32 GB RAM 2400 MHz

Even then, idling (no OS, just in UEFI mgmt.), the machine draws at least 112 Watts from the socket from which 64W go to the processor and 6 to the RAM (says iLo). The remaining 40 or so Watts are lost in the system.

When I install the 2nd CPU the CPU draw rises to ca. 120W, so I already got a good saving here.

Nevertheless I find this a bit too much, also considering some other testing labs results which seem to be significantly lower. For ex. see here, which supposedly not only shows CPU but the whole system consumption.

Do you have any explanation for this?

Thanks and cheers

    It is a meme post?

    It’s an enterprise server, with dual sockets, a lot of cores and ram. Not built with power saving in mind. And not built to be used on a home.

    Have you done any research before buying it? Probably no.

    That is normal power consumption behavior. And you are lucky that it consumes not that much for what it has.

      PSU have an efficiency curve, you would gain more efficiently with a load.

      This part is often overlooked for sure.

      If planing on running it for a while picking up a pair of lower wattage psus will often recoup its cost + help reduce noise.
