The most power-hungry CPUs consume about 115 watts I believe, but
they can be clocked down to slower speeds to reduce that. The trend
seems to be for less power-hungry CPUs though, the .65 process chips
draw less than the .90 ones for the same performance as an example.
The nVidia video cards are pretty power hungry, as is RAM. I have a
6800 card that gets very hot but even the 5200s get fairly warm.
I don't know how much power capture cards with hardware encoding
consume, but they seem to get pretty warm. My PVR-350 has a heatsink
on the video chip.
Myth backends are certainly not low power devices, but some frontend
configurations can be so.
