How much Electricty does a computer use an hour compared to a TV?

Answer 1

depends on peripherals and how hard the processor is working also, ate we comparing to a crt TV or plasma or LCD - same question on the monitor!

i would imagine like for like monitor/TV type then the PC will use more

if TV is a CRT and the PC monitor is an LCD then its about evens.

look on the back of your TV there should be a rating plate you are looking for how many watts the TV uses mine is a 39inch CRT so its a heavy user its rated at 550watts

PC has a 400 watt psu plus + a 100 watt flat screen monitor bear in mind these are max ratings not what they are currently drawing

Answer 2

A typical PC has a 300w power supply. An average tv about 250w. There's not a lot in it, but generally a PC will cost you more to run, per hour, than a TV.
If you know how much your electricity is per KwH you can work out the cost.

Eg. 1 KwH costs 12p

Running PC for 6 hours a day;

6(hrs) X 300(w) = 1800 (1.8 KwH)

1.8(KwH) X 12(p) = 21.6 per day

or £78.84 a year if used everyday for 6 hrs.

(I have no idea how much it is for 1 KwH, the above is just an example)

Answer 3

Computers are 110 watts for the little boxes sold at the department stores to usually 300 watts for the big desktops.

TVs vary by type. Old 25 inch CRT models from the 1970's used 300 watts or so but todays models use much less. You need to read the specifications for each model.

Your Cost equals (Cost per watt/hour) times (number of watts for the device) times (number of hours)

Answer 4

probably about 1½ to 2 times
Compaq 1905 draws ~150w
Sharp 26" CRT draws 97 w
