How much electricity a computer uses will depend on the computer's hardware configuration and what all applications are running on the computer. Processor type and speed, graphics chip or graphics card type, computer monitor type (CRT vs TFT/LCD) and other components of computer will determine how much maximum power it takes. At any time what is being done on computer will decide actual power being used. A computer can consume any where from around 100W to 500W or more based on configuration and applications. Specially high end gaming computers with high wattage graphics card consume a lot of power.
