MSI First with Motherboard BIOS that Supports Ryzen 9000 "Zen 5" Processors
In yet another clear sign that we could see some action from AMD on the next-gen desktop processor front this Computex, motherboard maker MSI released its first beta UEFI firmware update that packs an AGESA microcode that reportedly supports the upcoming AMD Ryzen 9000 "Granite Ridge" processors. The "7D74v1D2 beta" firmware update for the MSI MPG B650 Carbon Wi-Fi motherboard encapsulates AGESA ComboPI 1.1.7.0 patch-A, with the description that it supports a "next-gen CPU," a reference to the Ryzen 9000 "Granite Ridge."
A successor to the Ryzen 7000 Raphael, the Ryzen 9000 Granite Ridge introduces the new "Zen 5" microarchitecture to the desktop platform, with CPU core counts remaining up to 16-core/32-thread. The new microarchitecture is expected to introduce generational increase in IPC, as well as improve performance of certain exotic workloads such as AVX-512. The processors are said to be launching alongside the new AMD 800-series motherboard chipset. If AMD is using Computex as a platform to showcase these processors, it's likely we might see the first of these motherboards as well.

As for the other devices, those are powered separately by the motherboard and the signalling between them is state-monitoring. The signals don't really "leave" because current barely flows. Voltage can be measured across a very large input resistance, so using P=V^2/R, you get this:
Power use (of voltage signalling) in Watts = ~1.25V/10KΩ,
So about 0.0001W
People like to use water pipe analogies for electrical power through wires, and in this case, the signalling pipe is sealed at the receiving end with a pressure dial. Because the pipe is completely sealed, no fluid can flow, which means no power can be transmitted, but the pressure of the water can be read by the receiver on the pressure dial.
This should answer most or all of your questions

It is also demonstrable in practical experimentation

My 7800X3D shows 30ish W during RDR2 and if 3W of that is just for communicating with the GPU & NVME there is 10% of the power not as TDP. Its not absurd to think that with a 120W TDP it might show power consumption of 130 or 140W but only be dissipating 120W of heat.
EDIT** You are showing that a whole computer, NOT just the CPU, and they even mentioned that its the GPU that consumes the most power.
The 7800X3D is a special case, though, as it only consumes 80-90 W in a full load. The 120 W TDP is just a recommendation for cooling.
I'm saying the CPU transmits power to other components, just like a light switch and these loads through the CPU don't contribute 1:1 to the heat load.
If your CPU is consuming 100 watts of heat it will output 100 watts of heat. Most of that heat will be radiated from the CPU to the heat sink while some of the heat will be conducted through other materials connected to the CPU.
Because the CPU isn't consuming 100% of the power you give it other signals connected to the CPU continue working. (obviously)
