I have a RP4(4GB) sitting here in a Rocktech ISG-502 housing, which includes
a 12V DC to 5V converter.  Powering it from 12V, my power supply shows 2.55W
after booting (default install, no display/usb devices, one 1000baseT link).

Without the ethernet link, power consumption goes down to 2.15W.

That includes the losses from the DC/DC converter and some other circuitry
on the add-on board (RTC, RS232/RS485 interface).
