How many Kilowatt Hours does my PC use in 24hrs 1

[retrochoir]

My system is as follows:

Elite K7VZA Mboard, Duron 750, 196Mb RAM, 20Gb Hd, NVIDIA GeForce2MX40064Mb, SB16 Sound, CDROM Drive, 17" Monitor.

Assuming the monitor is in sleep mode for 18 hours, can anyone give me an estimate of the KWhrs over a 24hr period?

Cheers

estimate. No, I can't off the top of my head.
(and I'm not that interested to do the search)

I do know this: A MONITOR when in sleep mode, will use LESS
than 5 watts.

* Monitor has to be fairly new, with energy saving features. *Computer has to be set up to go into sleep mode.

My guestimate based on the time periods given would be around 7KWh per day...

Step one: Turn off EVERYTHING in your home, EXCEPT the computer.

step 1.5: go to electric meter and record the reading.

step two: Use computer as you normally would.

step three: after one day, go outside to your electric meter and record the new reading, subtract first reading from the new reading and you have the kilowatts that your computer used.

kwh use=kilowatts X 24
step five: turn stuff back on.

A joke: where do you find a dog without legs?
answer: where you left it.

GØAOZ,
I think you may be a bit over in your estimate, I run 2 systems that are comparable to the one in question, at least one and usually both would be running 6 or 7 hours a day (with monitors active). I use less than 10 KWh per day for my whole place, lighting, big refrigerator/freezer, TV, stereo, VCR, household and kitchen appliances, etc, etc plus the computers (cooking and hot water are gas and I don't have A/C)

Mulga, yes you could well be right! I did say GUEStimate, and of course a lot will depend upon what processes are running (not running) on that computer.

And to moliespal, you could find it in a bread roll with mustard and relish - i.e. a hot-dog!

Hi guys, ...... definitive....... kiloWatts x Hours = kilowatt hrs, so a system with a 300watt power supply using all 300 watts is 300 x 24 divided by 1000 = 7.2kwhrs. Power supplys are reflective... so if you have a 300watt supply and the system only draws 150 watts you will use 3.6 kwhrs. The efficiency is only about 95% so a small adjustment upwards. (the 5% dissapears as heat). Also take into account any seperately powered attachments, add them altogether and you have a figure.

hope this helps

My UPS's monitor power and most of my pc's average 145 watts. Keep in mind the power supply is chosen for worst case. That means all disk drives spining, fans running, and cpu at max use. That does not happen very often. It is probably costing about $0.30 per day to keep you computer on 24 hours per day.. ... your coffee pot cost about $0.15 per hour as does a microwave and toaster.
