Thought the same thing. I think I measured my gaming PC to idle at like 70–100 watts. Obviously an average office PC would be lower, but you also need to add on the energy for the monitor, which seems to start at around 15 watts for some basic monitors, and I imagine that's not at high brightness.
50W average doesn't seem absurd, peak power is going to be an order of magnitude higher, but computers are often running pretty close to idle...
