At absolute peak, the average gaming PC (assuming you don't SLI or anything else crazy) draws about 400w. Without knowing how much you pay for electricity, it's the equivalent of leaving 6 or 7 60w light bulbs on.
However, this is only during load (gaming or anything else intensive). Most of the time a modern Intel PC idles around 15-50w.
Obviously this doesn't include your monitor or any other peripherals.
Getting kind of off topic, but I was sort of wondering about this myself. Power consumption is one thing that worries me about the 780 GTX (and whatever cards come after). Yet, if I'm not gaming on my PC, I'm gaming on consoles that are hooked up to a power hungry plasma. Wondering if they would both be similar in that regard.
