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.
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.
