You need to know either the power supply current or wattage...
If you know the wattage of the power supply,
Then add a rough estimate of your monitor power...volts x 1.5 if you have
120 volts or volts times .75 if you realy have 220 volts...which I seriously
doubt since most house current outlets use 120 v.
So you probably use 200 watts for the computer and 180 watts for the monitor.
The printer is too small a drain to worry about.  Total is at MOST
380 watts... you are billed by the electric company based on your use
measured in kilowatt-hours..which is the number of watts you use times the
number of hours divided by 1000....so in 24 house you probably use
9.12 kilowatt hours.  Here in California where power is expensive
that would cost you at worst..if all is counted over base rate..
one dollar and nine and one half cents per day....
peanuts!
