Well, now I did .. after Proxmox install, we're heading the right direction: 1 CPU installed, 2x32GB RAM (as above) plus Raid controller P408i, 8x SAS backplane and 2x 10Gb Eth. NIC it idles at 74W out of which 15W go to the CPU. With 2 CPUs we get 87W in total with 19W on the CPU.
That's a completely different story. Was not aware of this ..
hmmm, was thinking about this, too. Let me check!
Apart from that - I need this thing kinda job-wise and it has been purchased with several future tasks in mind. Will be a Proxmox server for Windows/Linux on ZFS. So the choice of hardware type is no accident.
But it was indeed difficult to find out about power draw in advance. I researched it but did not get any great results. Servethehome was a source but for ex. it was even impossible to find out what happens if you pull out one CPU. The opinions about savings went from 0% to 50%. The board servethehome uses is this one
Thanks anyway for the (unforgiving) comments ;) At least good to know it is not that much for a server of this type. I'll get back to this post after installing Proxmox and updated power draws.
I set it to optimised for virtualization originally .. have to play around with this some more. Let's see.
