My Mum used to go on at me for being on my computer all the time when i was back at home. The other week she said the bill was higher now i'd left home :lol: :o Dunno what that is all about as they are only just starting to increase the price.

That Oxford uni link is well old, I don't know if those figures are still accurate.

Worth noting though, you can half your power consumption straight away by turning the monitor off....

>> HERE << one way to find out :)

>> And HERE << shows what a 350MHz system use in a year :thumbs:

a watt is a measure of energy transfer, not energy, so its not watts/hour. Still, 300w PSU wont use that much probably, so yeah, its comparable to leaving a few lightbulbs on. I think its around 8p for a kilowatt hour, so it will be roughly 50p a day but dont quote me on that cos i made it up :lol::lol:

well if it is a 300w PSU, then the maxium it will use is 300w an hour. However, at idle, it will be using probably 50% of that (google it for more info though). So that will be 150w an hour.

Get your lasted bill, get the price of a unit (usually per kW hour) then do the sum - ("kW unit price" / 100) x "psu wattage" ....and that will be the price per hour :thumbs:

:lol: thanks mate, must have came up with the thought as you were replying :thumbs:

just had a thought, is it comparable to say a 100w light bulb? ie having my computer on is going to be the same as having 3 x 100w bulbs on?

if your PSU is 300, then I doubt you will be using more than 200W of power...

just the same as 2 100W Lightbulbs on all the time...

excuse my thickness but will that (mine will be considerably less I would assume as the PSU is noly 300) make much of an impact on the electricity bill?

mine has a 550W PSU...

I'm usually always running at about 400W consumption tho due to water-pumps, fans, and also a hefty OC on my athlon chip...

Im always getting an ear full off my mam for leaving my computer on when Im downloading stuff as she thinks it will increase the electricity bill. How much electricity will a compter use :boggle: I know everything runs off 12v's or less but I wasnt sure it that would mean that it uses hardly any :boggle:

Thanks for any help
