How much more power is dissipated clearly depends on the quality of the PSU (constructing a power supply which is efficient at high loads and idle is quite a challenge). I doubt the BMC (sometimes built-in to the NIC) takes nearly that much.

That'll exceed 5W though.
- sandreas 2y ago> How much more power is dissipated clearly depends on the quality of the PSU Yeah I know - while "quality" (I assume efficiency) is not the only factor, because low tier PSU (<200W, like Pico PSU) are far less consuming below 20W. > That'll exceed 5W though. Only running all the time. Paired with a Tasmota Shelly Plug it consumes near 0W. Additionally it is Board independent and together with a HDMI- / USB-KVM-Switch it can be used for multiple hosts. I also thought about using PiKVM similar devices on my Banana PI 3 OpenWRT router, so this thing is running all the time and powerful enough to handle this.
- progbits 2y agoRPi 4 idles at around 3W and peaks at 5-6W so on average should be better.
- geerlingguy 2y agoMost of the boards I've tested with ASPEED chips consume between 5-7W when IPMI is running, and the system is powered off. They aren't all that efficient.
