The thread opener has ask about the superlative. :-)
IMO a Windows Server with tor is some kind of overkill, but on a Pi 3 you could use Windows 10 core and give it a try. Also BSD variants would be fine and bit more stable.
The power consumption of the RPi 3 depends on what your are using. Normally it would be around 5-6 Watts. On a RPi 1 or 2 you could reduce this to one or three Watts.

RPi 2/3 if I'm not wrong are around 3 Watts (fanless) An old P4... For sure it's not lower than 60 Watts power consumption
