How to configure Proxmox for the lowest power usage with approximately 5-6 watts

root@pve-02:~#

root@pve-02:~# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors

root@pve-02:~# echo „powersave“ | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
powersave

The command to set the power state needs to be given after every Proxmox restart you can automate this by having a ‘@reboot’ entry in your crontab

@reboot echo „powersave“ | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor >/dev/null 2>&1
