I'm not the person who you're responding to, but at least in my case I am just not comfortable with having the ability to switch, since I would like to connect devices which could be seriously damaged if the switch toggled for any reason. I have modified a couple of switchable power monitoring plugs already, but I would rather pay slightly less and not have a hassle.
I run a 1600X as a Proxmox host, I have used TLP to set all of the configurable that are exposed, and it idles at 70W.
There are a few other things consuming power though - a spinning HDD, a discrete GPU (quadro K2200) doing zero work, and four DIMMs.
This is helpful to heat my apartment in the winter, but regrettable overall.
