Take a look at this Topton X86 2x i226-V 2,5G Nics Fanless Mini PC J4125 J4105 - It's cheap but only has the j4125 (still a decent CPU!)
It also depends a lot on the OS ability to send the device to the lowest power state. My machine is running proxmox, together with cpufrequtils / sysfrequtils. There's a setting in the bios for the minimum cpu frequency that you can also alter. By doing this, I'm getting my machine to run around 1ghz in idle and stays for most of the time in the C2 or C3 acpi states. This is the output of Netdata for the past few minutes. You can see the drastic change in frequency after setting the correct values. My current bios is set at 1ghz min frequency, but I could drop it even more.How can the N5105 in this video get even below 4W? I ordered the N5100 instead of N5105 specifically for the lower TDP, and now I am quite buffled to see they behave pretty much inversely to my expectation
Same in my country ....but they usually install C .... C is for high powered devices like angle grinders or hydrophores in deep wells, that when start they pull lot of power. Sure in that case you need to use a C curve because B will trip instantly.
I took a bit of time to fiddle with the BIOS setting you mentioned. None of them resulted in a lower TDP when idle, so the summary is:
- ~ 9W running idle, ~ 23 W under load, ~ 1.7W powered off.
So I took a look at the CPU Wattage in HWinfo, where I saw that the CPU was drawing 3 - 4W on idle. So I guess the power transformer might be inefficient. I tried other two supplies I had around (also cheap ones) and there was no difference. I've tried switching the NVMe with a SATA SSD and the TDP stayed pretty much the same. There was nothing else connected.
All this led me to another think I don't get. Take a look at the TDP of J4125, N5105 and N5100: View attachment 25127

Can you tell me the specific bios setting that changes the minimum cpu freq? I suspect we're not talking abou pl1 or pl2 here.
do you have recommendations for a decent psu?
I've tried windows and linux. The lowest I got was on a bare install of ubuntu server. Was idling around 7W.
and apropos my 'obsesion' with low TDP, I have a MSI Cubi 5 10M-033EU that I use as a home server. That unit has a i3-10110U cpu and it idles at 6W measured at the wall.
no... I am planing to use it with pfsense, but I need to get to know the machine a little before that. A bit of foreplay if you will

Do you want mSATA or m.2 NVME? 4 or 6 LAN ports? COM Port? Several displays?
I need only 2 ports, one display to install OPNsence, disk doesn’t matter I think. I want just bare metal OPNsence with Adguard.
In this case I would go for a 4 port with m.2 NVME (mSATA is a dying interface, NVME seems more future proof). I don't see any reason to pay for unused features.
So I finally had some time to do some testing and I can confirm that if you are using v3 or v4 (v5 has an additional clock so does not have this limitation);
