Do you happen to have wall power consumption readings at idle for your Mini-PCs?

[trs-80]

You asked about mini-PCs, which I don't have, however just for comparison I can say I have ODROID-XU4 + cubietruck here running and only drawing about 2W total between both of them.

I wouldn't necessarily recommend those (especially the cubietruck) these days, but there are lots of Single Board Computers (SBC) out there besides RPi.[0]

My BOSGAME B100 is 7W idle, 19W with peak synthetic load. That includes a 3W external spinning drive.

Not the OP, but my ASRock N100DC-ITX idles at around 9W at the wall.

I have an Asus PN42 with 512 GB SSD and 32 GB of memory idling at around 7 W (default Debian install, without monitor connected).
