Can you give some details (components and consumption)? I'm interested in the topic, and I've done some wall measurements as well, in the past and present.

My 3900x is also very inefficient when idling. It never goes below 50w according to hwinfo64. My entire pc is surely above 100w idle.

  Interesting, I'm currently running Windows 10 with a Ubuntu desktop in a VM and multiple web browsers open with lots of tabs. According to Ryzen Master, my 3900X is consuming ~25-30 watts. Edit: Libre Hardware Monitor shows package consumption around ~55 watts which looks suspiciously close to CPU + chipset power consumption.

I have a 3950X and a 5950X. I thought it was the other components at first but then someone pointed me to the official Ryzem master software. It shows CPU package power, which has a persistently high floor consumption. Idle temps are also higher on the same cooler. It’s a well-known phenomenon on the forums when I searched.

  FYI some programs really fuck with this, even at ""Idle"". On my ryzen 5 3600, it idles at a few watts, but if I open steam and just let steam idle on my library, the CPU now draws 15 watts.

My 5600G idles at 22W whole system (wall power). However it has the cheaper chipset, not the x prefixed one, no video card at the moment and just one NVMe ssd for storage. It does have 4 x 16 Gb ram sticks so you can go even lower if you get 2 x 32 i guess.

  AM4 APUs are totally different from their CPU brethren and are much better behaved in this area, because they’re socketed versions of the mobile chips.

  Interesting. My 3950x draws (wall power) approximately 67/68W in idle. I'm on a Bxxx chipset and a 6600 XT, which should both consume little in idle mode, and 3 SSD, which consume little. I haven't read much, but it t seems the range of around 40/60W seems fairly normal in idle, for a modern system (both Intel/AMD). I remember a former system of mine consumed 32/33W though; I think it was an AMD 6800K.

    Well I picked the 5600G because it was advertised as 65 W (well and because it allows me not to decide on a video card yet). Your CPU is advertised as 105 W. TDP is a lie these days but the lying should be proportional :) At a quick google, the 6600 xt idles at 4W with one monitor but at 20 W with two! Plus whatever extra power the motherboard needs to keep that pcie slot active. Two extra ssds may consume little but that can be like 4-5 W more. It all adds up.
