How much will a 1200W PSU raise my power bill?

[Blackout621]

If I use a computer powered by a 1200W PSU 2 hours a day on average, how much do you guys think it will raise my power bill? (Duke Energy)

Depends whats in the computer, the PSU only pulls enough power to give the system what it needs so a 1200W PSU running a 100W system isnt going to be pulling 1200W from the wall, because its got some inefficiencies in it, it would likely draw about 140W from the wall, if its actually supplying 1000W of power to the system then its going to start to make a dent in the power bill at about 20 cents/hour, its going to take a long time to add up to anything significant.

Depends on the actual draw of the unit, most PSU's don't get up to 100% anyway, so you'd have to measure that. There are meters you can buy which will tell you the actual draw though, you just plug it in, and it'll measure it up. Then you can multiply it by how much Duke Energy charges per kilowatt hour.

I'd say a quarter a day, but that's just going off the cuff, not an actual measurement.

Thanks for the advice. You were pretty close, it would cost $6.37 to use it 60 hours/month. So I'm fine with that.
