A normal desktop computer use power anywhere between 60 and 300W. The wide variation can be attributed to presence of additional devices, for e.g, a powerful External Graphics Card can take the power consumption to higher levels, while computers which use inbuild Graphics consume less power. Computer monitor is another component which consume lot of power. An LED monitor consumes power around 20W with slight variation as the monitor size increases. A purely LCD monitor consumes more and the older CRT monitor consume around 80W. If the computer is used to play games or run powerful software, it consume more power as more resources are activated to run this application. The more you work on your computer, it will again increase power consumption as the computer gets heated and the fans will have to work more vigorously to cool it off.
Laptops on the other hand is more power efficient as it consumes around 15 – 60 W based on the configuration.
