I know it depends on how much you run it and how much power it takes but can I get some rough ideas or something? I'm sick of hearing how the power bill is high because of my pc. Even if it is I'm still denying it :p
 
Check this out

Computers account for only a fraction of worldwide electrical use, even with the burgeoning Internet. Air conditioning, lighting, and refrigeration account for a LOT more.
I liked that line. Show that one to your folks.

I calculated mine and for 12 hrs a day, for 1 month was $5.22. That is assuming my monitor is on the entire time my computer is on.

well lets say a high end PC actualy uses 400 watts continuous....which is pretty high really.
say 12 hours per day, 30 days a month thats 144kwh....I think I pay around 6.5 cents per kwh, so that's around 9 bucks a month...not bad when you compare that to an AC unit or refridgerators.

Hmmm so I have 2 PC's running with 3 CRTs (no lcds yet), so it's costing me like umm more than 9bucks a month! :p
 
probably not. 400 watts its very high. My system with a 17inch crt on consumes about 270 watts, about 80 of which is the monitor, and I have 2 hdd's and 2 optical drives.
 
How do you calculate? using the PSU rating (at 100% efficiency)?


what about the moniter?
 
I have a ups that tells me in its software how much power is hooked up to the actual battery back up plugs. Just because you have an xxx watt power supply doesn't mean you are using all of that. There needs to be a bit of overhead.
 
I'm averaging about $25 per month increase when my main's on 24/7. But then again most people don't juggle 5 internal hard drives, 2 printers, and enough USB cable to completely wire up the Empire building. :D
 
4ghz...that's kinda hard to say unless that's in the winter when using propane for heat...cuz in the summer with AC it's always changing and fluxuating.

Just some random numbers I put together....as you can see computers don't draw that much really. Now, OCing them doesn't have a large increase in energy, but upping the voltage does. If you use watercooling and go hard on the chips and video card your looking at about another 100 watts.

phase changers....that's probably like running 4 stock computers if not more.

This agrees with my experience as well, though the only calculation I had to do was to notice the difference in my hydro bill from before I got the computer! :cool:

Thanks guys. I pay 12.1 cents per kilowatt hour :bang head

Be glad you don't live in NYC. I'm paying $0.13/kwh. My computers account for about 80% of my electric bill.
