Most Pc's have power supply units of 200-300 watts, so in one hour will use about 300watts max., or 0.3 kwh. If your energy cost is 12p per Kwh then it will cost you about 4p per hour but will probably be nearer to 2 - 3p.
SS4- You better take a look at your calculations again! Where did the 3600 come from?????????

i'm guessing the p is for pound.....and final time I checked a pound became into like $a million.seventy two in u . s . money. NO way it takes that lots money, least interior the u . s ., to gentle a delicate bulb for one hour. you will pay that for the entire month for one lightbulb...in line with possibility if it became into left on finished time. a pc right here interior the states would use approximately 8 cents of ability in line with day...there are a hundred cents in a u . s . dollar so which you do the conversion.

this does depend on the power supply
for example my setup
on pc 1
p3 machine with 900w psu (with a silly raid array)
pc2
p4 with 210w psu
machine 3
apple imac 90w total useage including monitor
pc4
p1 NAS 4 200gb hard drives (100w psu)
these are always on and i use about £2 a week (on average including router, monitors, switch, and additional water cooling power supplies addas another 2 a week)
in an hour they only use a few pence

It depends on your supplier, I'll assume 5p and 10p per kWh as my boundaries.
For my laptop (uses less power), it draws a current of 3.42 amps and a pd of 19V
This means it uses power VI and energy VIt
So, per hour it uses: 19*3.42*3600 = 233928W = 234kW
Since it uses 234kW in one hour it will be between:
234*0.05 = £11.70 and 234*0.10 = £23.40
