hi guys just was curious about how do i calculate the "units" of electricity my Pc takes per month ???? according to PSU calculator my pc pulls 307w

370*(number of hours pc is on per day)*30/1000

Convert your load into Kilowatt and multiply by hours to get units.

thnx guys it pull wooping 221.04 per month if i use it 24/7 :shock::shock:

^^if you have multiplied it according to 24/7 then i guess it is for a week.correct me if i am wrong.

and and and, that is assuming your PC runs on full load 100% 24x7 consuming 307w continuously. Which will NEVER happen.

Your PC isn't going to run 24/7 at its full load condition. Idle power consumption is lesser than this. ;)

its at 100% load atleast the CPU :) :p :wink:

na its for a month buddy my electric bill goes up around the same 500 extra :p

Calculation :
Efficiency = Input/Output
If PSU is 80% efficiency rated then IT means it gives only 80% of the power taken from mains to the Hardware .. The rest is wasted as heat ...
Hence your machine needs more than the rated power to meet its requirement.
ie: 100/80 * PSU wattage ... And you multiply the it with time you use it(in hrs) ...
It gives you kWh`s .. Multiply the kWh with with the per unit rate of your electricity supplier ...

Hence Cost = 100/(PSU Efficiency) * PSU Wattage /1000 *Time (in hrs) * Cost per Unit

This gives you a rough idea about how much electricity your machine consumes ... Actual values are different for many reasons ...
1.PSU efficiency is calculated in a controlled enviroment in the lab
2.Voltage fluctuations around the country
3.Surrounding temp of the PSU

These factors contribute to the overall performance of PSU .....

at the end it show 123.xx that means it pull 123 units or KwH??????????/

Unit used for electricity = kWh. :| 5 units of electricity = 5 kWh.

Electricity

The energy unit used for everyday electricity, particularly for utility bills, is the kilowatt-hour (kWh), and one kWh is equivalent to 3.6×106 J (3600 kJ or 3.6 MJ).

And stop using so many question marks.
