Another question: do you know what you UPS is pulling? Recently had a really good offer on one, but denied because power here is really stable and i thought i can safe the watts.

My whole homelab pulls something like 150 for 2 Servers (one ryzen 5 and one i3 8th gen). 200 seems not so much for urs. Have you done any power optimisation on your machines?

Not so high because of frequent updates and reboots for security
