how much electricity does it take to run a computer 24 hours a day?

Question

the wattage to run a computer --trying to see if using the computer runs up the electrical bill

Answer 1

Running a typical PC is about 200W. That is like leaving two 100W light bulbs on all the time.

Then you have to add the monitor. If it is an older "tube" monitor it also takes a lot of juice. Having you computer turn off the monitor when on screensaver helps, but not completely.

Another thing is that these things generate heat which might cause your ac to run more.

I guess the answer is yes, the computer could affect your bill.

Answer 2

I have an older computer with an old CRT tube monitor and I know for a fact that it doesn't use up that much energy. It does when I leave the monitor on, but I've made it a habit to turn the monitor off every time I step away from the computer. This saves cuts back some of the energy, but a good ol' LCD is a worthy purchase. They save a lot more on energy costs than the monitor is worth in some cases.

Answer 3

It does depend on your computer, but I would roughly estimate 150W, plus about another 100W for a CRT and about 50 for an LCD. So I would estimate at 24/7 you would use 180 KW hours in a month with a CRT and 144 with an LCD. That is a pretty decent amount of electricity, of course most people don't leave their computers on at night, and you should never leave your monitor on when you are not using it.

Answer 4

Depends on the powersupply. Not much. I leave mine on 24-7 and just kill the monitor.

Answer 5

DUH!
Depends on the computer.

Is English your second language by any chance? Nonsense, jibberish moronic babble - cease and desist!

Answer 6

uh idk but mine runs all the time but its got a thing that puts it to sleep when its not being used
