An average desktop computer uses between 60 and 300 watts. It is very difficult to know exactly how much computers use on average because there are so many different hardware configurations.
For example, as of 2014, the average laptop draws 20 to 75 watts, while a coffee maker uses 600 to 1200 watts to run. If a Keurig coffee machine remains plugged in, it requires 200 to 400 continuous watts, and a maximum of 1,500 watts. A laser printer requires much more wattage, with roughly 2,000 watts at its peak.
