  • How much electricity does the CPU takes?

    Sorry if I've posted in the wrong section. But I'm curious to know. I always leave my pc on overnight. But I'm wondering does it uses much electricity? Could someone give me an example like same usage as the TV or fluorescent light or a 2 horse power aircond? Thanks..:bounce:

    depending on what is ion your PC, its pretty safe to assume that its about (2) 60 watt lighbulbs burning.

      I have a 2 GHz prosessor, 256MB DDRAM, Geforce2 MX400. But does it take as much as the air cond usage? So I guess the CPU doesn't use that much right as a 120 Watt bulb? BTW what if it's compared to a 43" TV? oh ya I always off my monitor when I'm away..does this helps to save electricity? Hope to get a reply. Sorry If I'm a noob..:hammer:

        your computer doesn't use nearly as much electricity as an AC unit or a TV. Your monitior (assuming it's a CRT) uses up the most electricity, which is comparable to a TV. So if you leave your box running 24/7 it's not going to send your electricity bill soaring.

          Probably in the range of <$1 a month.
          It costs more to leave lights on in rooms when you are not occupying them.
