Improper question; change the question so it is either "How many kWh per hour does a computer use?" or "How many kW does a computer use?" The term "kW" means "kWh/h."
On the average, a home computer of current manufacture consumes about 0.25 kWh/h

∙ 12y agoit depends
laptops are between 68 and 120 watts
a desktop will depend if you're just talking about the tower or the whole thing that's needed to be on so you can use the computer.
CRTs generally use between 15 and 50 watts, The Mouse/keyboard is like 1.5-2.5 wattsif you have a glowing keyboard then its like 3 wattsyour speak system will vary from 5 to 300 watts, depending on what you have. the average is under 50 watts. A low-end speaker (basic) is like 9-13 wattsYour printer is about 11 watts, and the scanner is between 10 and 25 watts.
Your computer will also vary in wattage depending on temperature too. its not much though, less than 5 watts difference. Its consumed by the fans to keep your CPU and other parts cool.
Desktops:low-end150 to 250 watts
general comp, at least 3 yrs old200-350 wattsgeneral comp, newer than 3 years200-300 watts
multimedia250-400 watts
a general gaming or workstation300-500 watts
high-power workstation300-600 watts
high-end gaming (older processors, at least 1 year)500-1000 wattshigh-end gaming (with newer processors)400-800 watts> the difference is that newer processors uses less energy and speed to do the same thing, they run cooler and uses less energy even when OC'd.
custom computer can be between 300 and 1500 watts or more. Most consumed by overclocked processors, graphics cards (more than one usually), extensive cooling system that can range from a water cool to phase change cooler. Some computers use TEC coolers, further driving up power usage.Source(s):my computer uses 248 and laptop uses 68. The computer i wanted (with tec coolers) would consume 450 watts for the CPU, 400 watts for graphics 2 cards, 100 watts for everything else, and 400 watts in cooling. Its about 1400 watts total. If I use a newer processor and graphics, it'll drop to about 800 watts.

How many kilo watts does a 5.5 watts water filter consume in one hour?
5.5 watts is 0.0055 kilowatts. in one hour the equipment uses 0.0055 kilowatt-hours.
How many watts does an average printer use?
about half as many watts as the computer per hour a computer uses 200-500
How many watts consume a medium refrigerator?
The fridge consumes the watts. My fridge is a normal one, it consumes 500 watts for 2 minutes every hour.
How many watts does a light bulb use per week?
Your question is rather like asking "How many miles per hour do you do in a week?" You don't consume watts over time, it's a measure of how many joules of energy you consume over time.
How many watts does a iron consume in an hour?
A typical iron uses 1000 watts all the time the heating element is working. It is controlled by a thermostat so the element might be on for a quarter of the time. In an hour the iron might consume 250 watt-hours or 0.25 of a unit.

too many About 2 million

How many watts does a microwave consume in an hour?
Watts are units for measuring the rate of energy consumption. So it is meaningless to speak of how many watts something consumes in a length of time. (It would be like asking how many miles per hour a car drives in an hour.)Energy consumption may be measured in kilowatt-hours. A typical microwave consumes 1500 watts, which would be 1.5 kilowatt-hours in one hour.
How many watts does grinder consume?
A small coffee grinder 100-200 watts.
How many watts does a fan not in use consume?
none
How many watts per hour will a unit that is rated at DC 12V 500mA consume?
Power = volts x amps, so your example will be 12 x 0.5 = 6 watts. (500mA = 0.5 amp) Note we don't talk of 'watts per hour', it is just watts. 1 watt = 1 joule per second
1000 watts rms consume how many kw?
"Watts RMS" is better represented as "Watts average". Since 1000 watts is 1kw you have "1000 watts average" and you can derive "1Kw average". So 1000 watts RMS will consume 1 Kw
How many kliowatt hours does a 120 watt fixture use in 1 hour?
One kilowatt hour (kWH) is the amount of power used at the rate of 1000 watts for one hour. Therefore a device of 120 watts running for one hour would consume 120 / 1000 x 1 = 0.12 kWH
