power usage

[bartplessers]

I recently switched to proxmox on a
Dell OptiPlex 7050:

• 3.4 GHz Intel Core i5-7500 Quad-Core
• 32GB of 2400 MHz DDR4 RAM
• 512GB SSD NVMe PCIe
• no spinning disks

baseline power consumption: 28W (thus without any VM's running)

Is this OK? Some people suggest that it is rather high, but when I run

echo "powersave" | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

there is no change in power consumption.

So just wondering: is +/-30W normal for such a system, or can I further optimize the power consumption of such a system?

kind regards,
Bart

You could try to disable onboard stuff that you don't need like aditional nics, disk controllers, soundcard, usb controllers, ...
Then there is aggressive link management but this might be bad for data integrity.
And for the CPU governor you could try schedutil in case that is supported when powersave won't help.
With SATA you could use hdparm to set a lower APM value, but not sure if something simlar existis for NVMe.
