In my room, my desktop PC has a 1000w power supply. Granted it rarely, if ever, uses 100% of that, but lets say 500w to be safe. Most space heaters run 800-1500w. So My PC is like a small space heater thats always on. Add two large monitors, lamps, an air filter, etc, and I end up leaving my window open in the winter to compsensate. Its 57 degrees (F) outside right now and my AC is on...
