Just doing some research into finding out how much it costs to run a computer 24/7 from home?
Any one have any info?

best way to get your answer is to buy one of these .....

it will tell you exactly how much power you are using over any time period you decide .......

plug the unit into your wall socket ..... and your multi socket power strip into the unit and off you go ....

It couldn't be simpler to calculate ,

Electricity is charged for by the KW hour , thats Kilowatt hour , a kilowatt hour is one unit of electricity , the price for one unit is on your bill.

Lets assume you have a 500W power supply in your PC , this is the maximum power you can draw , 500W = 1/2 kilowatt , so assume your PC runs at maximum , then you use ,

500W x 24 per day , thats 12 kilowatt hours or 12 units ,

Now the last bill I looked at Electricity was 12.73 cents per unit , ( ex VAT) ,
So thats 12 x 12.73 = 152.76 cents per day , remember thats cents so lets round it up to 1.53 euros a day. Add the VAT ,

1.53 x 1.135 ( vat is 13.5 % on electricity ) = 1.74 euros a day or 12.18 euros a week to run it 24 /7

Now in practice , your PC will never use the full rating of its power supply , so in reality you are looking at about 50- 60 % of that figure , or approx 7 euros a week to leave the PC on 24 hours a day.

The monitor should be using about 40 watts , this is more than swallowed up the the assumptions made above so well take the monitor power usage as negligible.

A pittance I think you'll agree !!

Also wasteful , why leave it on 24 hours a day at home ? Is someone going to be using it 24 hours a day , or maybe you want to leave a Web server on for 24/7 ? If thats the case then you can run with a much smaller power supply , no monitor etc., and reduce the costs accordingly !

P2P, SETI@Home, Rosetta@Home, various other reasons. Wastefull true, unless you absolutely need to have it on.

You need to tale into account efficancy of the psu, cheaper models may only draw 350watts full load, that doesnt mean they dont pull down more at the start. Most good psu's pull in about 85% efficany, bad ones about 50%.

I have an old pc with a P2P client on it that has a PSU with a rating of 110W and no monitor (use remote desktop on it) saves me ~ 400wats an hour when its on and the main/this PC is off .
