What computers use what amount of watts?

Answer 1

it depends on the computer or laptop taken into consideration

it could vary from laptops using 50watts to computers using 300+watts

the one I'm using know states 90watts but that doesn't mean a thing since most of the time it uses less, or if it in sleep mode it uses say about -20watts

My HP ProBook uses 20 watts when idling to 50 watts with max processing.

Answer 2

This varies WILDLY by computer, and what you are doing at the time.

Some computers, such as VIA based computers, may use less than 15 watts total.

While, typically, most laptops use between 45 and 175 watts.

Desktops vary the most, and can be anything from 10 watts (VIA) to 2000 watts.

A computer cannot use more than it's power supply can provide, so if it has a 650w PSU, then it is unlikely to draw more than 650w.

Most computers draw only 1/2 to 1/4 of their power supply when gaming (unless a much larger PSU than needed was chosen) and 1/5 or less power when they are idle.
