Specs:
Ryzen 7 3800x
Asus ROG Strix B550-F Gaming
GTX 1080
G-Skill Aegis 3200mhz cl16
Crucial P5 Plus
Some AIO Cooler 2x140mm
be quiet! PURE POWER 11 FM | 750W PC-Netzteil

Recently i took an old computer and made it my nas. To read the power i bought something to read it directly from the plug,
it was only 17 watts while idling, which is good so i wondered what my main PC was using. 104W while idling. I was unsure
if that could be right. I reset my bios and only turned d.o.c.p on, everything else is stock, but that didnt change a thing.
HWInfo, Coretemp and HWMonitor all say the cpu is using 22W in idle and the gpu is using 42W. That would be 64W so where
do the rest of 40W come from? M2 ssd shouldnt even use a Watt in idle, so is it really motherboard, cooler, ram and maybe some
power supply inefficiency? The CPU also isnt dropping clock down more than 3599mhz, are there any bios settings that could
help me get less power consumption?
 
Anywhere between 15-25W is not out of the ordinary for 1CCD chiplet Ryzens, 3000/5000/7000.

Your GPU is really bumping up your idle power (I'm assuming you are running multiple high refresh/res monitors to warrant max VRAM clock at idle on your 1080 Ti for 40W), but 40W of misc power is not unreasonable. I am regularly about 100-120W at the wall, with 20W CPU and 10W GPU, with a bunch of NVMe and SATA drives and fans, albeit with a monitor usually included in that figure.

"Isn't dropping clock below 3.6GHz" is not understanding how any Ryzen 3000 and later fundamentally works. If it wasn't power gating CCD properly and dropping Vcore and clocks at idle, you would be seeing more than 22W.
 
"Idle" on a modern PC isn't "idle" as such either. There are heaps of background tasks going on at all times. Plus the PSU will be what, 85ish% effective at low loads? Meaning if the power read thing read 100W the computer uses 85W. Add a couple of fans, and a quick googling says pumps use 20-30W. 22+42+25 and there's your 85W.

One 144hz 1080p Monitor through dvi and one 1366x768 60hz monitor through vga to displayport adapter (want to replace it in a few months when i got enough money). Im a freak when it comes to reinstalling windows so i even tested it with a fresh windows, hwinfo etc. show up 40W on GPU, with what ive red that seems pretty high.

Ohhh, i found the issue. Its because i run one with 60hz and one with 144hz. So i removed the 60hz Monitor, it stayed at 100W, i restarted and now its 60W in idle with only the 144hz Monitor. I plugged the 60hz Monitor back in and its 100W again. When i run both Monitors at 60hz the idle is now 60W instead of 100W. Hwinfo etc. now says the CPU is using 19.5/20W in idle instead of 22-24 and GPU is using 9-10W instead of 40. The calculations dont add up though, GPU is using 30W less and cpu just 2-3W less, Plug measures 40W less though (probably because of less fan usage because of less heat because of less gpu usage lmao. The problem is i of course still want to use my main Monitor at 144hz and i of course still want the second Monitor because single Monitor sucks...
 
are there any bios settings that could
help me get less power consumption?

Sell it or keep it and let it do his thing....

Sounds about right, if your CPU and GPU are pulling that much. Measurement from the wall is higher because of PSU efficiency losses.

e.g. A system that consumes 100W, with a PSU that runs 85% efficient at that load level, will draw about 100/0.85=117W from the wall.

The real headscratcher is why your 1080 is chugging so much power at idle?

Yes, this isn't too uncommon for older GeForce. Ampere and Ada improved multi monitor VRAM behaviour a bit. On 1070 and 2060 Super I was generally up in the 20-40W region for a mixed setup like yours. On 3070 Ti that came down to 20W, same deal for 2 x 1440p165 displays. On 4070 Ti now it's sub-10W.

You can play with the usual CRU blanking times trickery to see if it works, but there's not much else you can do. When it comes to monitors, whatever the GPU says it is, is basically the power draw you're stuck with. Both GeForce and Radeon.

The difference in CPU wattage is margin of error and doesn't mean anything, it has nothing to do with how Ryzen idles. You should know by now that CPPC makes both idle and boost extremely unpredictable.

High refresh rate + multi-monitor bumps your idle GPU power by a lot, depending on which model you have. Radeon and older GeForce cards work harder and keep the VRAM at higher power states to feed your displays. My 7800 XT consumes around 38-45 W running a 144 Hz 3440x1440 ultrawide and a 1280x600 mini display, and that's the GPU alone. 100 W system idle with such a setup is not uncommon.
 
"Idle" on a modern PC isn't "idle" as such either.
^^^This^^^

It is important to note the ATX Form Factor standard requires all ATX compliant PSUs to output +5Vsb standby voltage to multiple points across the motherboard when the computer is shutdown, the power supply is still plugged into the wall, and (if equipped) the master power switch on the back of the PSU is set to "|" or "On".

This +5VDC is used to provide power to many things, including the motherboard so the case's front panel power button can function. It also keeps many circuits "alive" for various functions including Wake on Mouse, Wake on Keyboard and Wake on LAN. If you can wiggle your mouse or press a mouse button or keyboard key to wake your computer, power IS being supplied to the applicable USB ports your keyboard and mouse (or their wireless dongle) are connected to. This +5Vsb voltage is also used to keep data in memory using a low voltage state for faster boot times.

Oh, and note idle is much different than sleep. All of the above I mentioned are for sleep modes. A system at "idle" would use considerably more power.
