I have no hopes of getting this answered but here goes anyways ...
Is there any way to figure out the damage that is done on my electric bill when i keep running my pc for 24 x 7 ???
My mom seems to be getting super pissed about the bill and i try and pass it on to the geyser .

When i bought my first comp in 2002 people used to say then that it eats something around a 21 inch tv , i dont suppose that holds true anymore ..

Please guys , rack your brains and temme how :huh:
 
How much does a unit of electricity cost?
One unit should be 1000 watts an hour. You probably must be using 500 watts an hour or lower. It may be around Rs. 5 per unit, but I am not sure.

Multiply no of units per day X Cost per unit to get the daily bill.

According to me a computer today that can be classified under recent stuff should take as much or more power than a CRT TV.
 
sharekhan if u tell us ur pc config it would be easier to calculate the power consumption.

let us assume that ur pc draws 100 watts and ur monitor draws 100 watts too(rounded up generally not so high)

now if keep only ur pc on with monitor off daily unit consumption shld be 2.4 units . with monitor on it shld be 2.4+2.4 = 4.8 units per day.
Which means 144 units/mnth if both are kept on and 72 units /mnth if only pc is kept on.

Now its not possible that u keep ur monitor on the whole mnth u must be keeping it in power saving mode /switching it off when not using it.

So based on that u need to calculate the power draw of ur pc.
At 5rs/unit if ur power draw is between 72-144 say 100 then it adds rs 500 to ur bill.

Now i do know that pcs at idle consume less power than at full load this was just an assumption based on which u can calculate ur pc power consumption.
Now if ur pc is high end one then it would draw atleast 150 watts at idle and upto 200-230 watts on load.(without monitor).
if ur pc is a highend one its not recommended keeping it on for dloading etc 24hrs a day. use a secondary pc for that purpose.

To measure powerconsumption of electrical appliances @ home u need something like this
 
Why is it not recommended to keep a high end PC on 24hrs of the day?

It is safe to keep it on 50-75% of the time in a week?

Click to expand...

what i meant was ,'not recommended from cost point of view'.if one can afford the electricity bill they can very well keep it on all the time:).
 
Well This is My rough estimation based on my personal experience ....... I too Run My Pc 24/7 coz of the Downloads with my monitor turned off most of the Time ! The Difference in my electric Bill is Roughly 400 Bucks !
 
All of us forgot one thing, one very important thing. Most PSUs have an efficiency of 70% or lower. This means that for each 100 watts the PSU takes from the UPS, only 70 watts or less can be used for the computer, 30 watts is wasted. So even if your computer does need only 100 watts, you will end up taking 100 X 100 / 70 watts = approx 150 watts.
70% is also the efficiency of value PSUs albeit from Antec, generic brands may be even worse.

Also, a high end PC can easily take 300-400 watts under full load.

Remember, Va of UPS should be 1.4 X watts of system

Anyway, I think I deserve some greenies for all this!
 
i have a 19 Inch wide screen monitor which is on for about 5 hours on weekdays ....

A cabby wich runs at idle for around 22 hours or so ....

i have 3 HDD 1 DVD RW , amd 2800+ asus K8s MX board , 1 6600GT ATP3 speakers ..

so more or less damage is 1K is 700 rs Pm i guess ...
