My desktop PCs have always been idling at more than 50W. Granted, my newest one is from 2011 or so.

I don't think it has improved much. No one has been benchmarking these metrics for desktop PCs for a decade or so, so they have gotten worse, if anything. I have not yet found any LGA 1700 motherboard were the total idle power would be less than 25W, for example. I find that the power supply inefficiency by itself, even on standby , is usually already 2W -- larger than some of the alternatives discussed here. I have to go to Intel's soldered solutions to find <10W idle consumption (and even <2W). Forget about last decade's desktop AMDs either, they have very high idle power, with the exception of some APUs that may go down to 10W. They may also have custom solutions that idle at significantly less, though.

  Yes, this is a shame. Building a low-idle-power system with desktop components is far harder than it seems, unfortunately.

  There's a German forum where they've been crowdsourcing this info for a few years[0]. According to their spreadsheet[1] there's a few systems with 12th gen Intel cpus with <15W system power, and it looks like those are using bigger psus so they might be able to be lowered still with something like a Pico PSU. There are lots of low power LGA 1151 setups so as you say things may be getting worse (or the contributors aren't using new computers yet). I think newer pcie generations have higher power consumption, but I don't know if that's true when you put in a lower generation device into a pcie 5 motherboard for example, or if it affects idle power or just peak. It would be nice if this info were more readily available.
