How much electricity and power is consumed when computer system runs for 24 hours?

Question

how many units in elctricity meter does it make when computer system runs for 24 hours . does it cause too much money in the electricity bill

Answer 1

It depends on your computer and its peripherals.

I have an HP Pavilion, with CMV Model CM-922D monitor.  Here are the wattages I measured:

COMPUTER AT REST         6 WATTS

COMPUTER IN USE           62 WATTS

MONITOR AT REST             2 WATTS      

MONITOR IN USE              58 WATTS

MODEM                                 4 WATTS

SPEAKERS                             1 WATT

So at rest I am using 13 watts

Answer 2

A typical desktop computer uses around 200 watts while idling.  This can be increases if the computer is performing an operation, or reduced if the computer goes into power-saving mode.

200 watts = 0.2 kilowatts

Energy = Power * Time

E = P * t

E = (0.2 kilowatts) * (24 hours)

E = 4.8 kilowatt-hours

That's how it would show up on your electricity meter.
