Hi All,

I have moved into my girlfriends and everyone is worried that my computer is going to use alot of electric... i've estimated it at around £6.00 per week... based on 1750KWh a year... but I want to be more accurate... is there software I can buy or a components that I can install to measure exactly how much power my rig is using?

I don't want to use a multi-metre or anything that means I have to keep manually testing it...

That's at full load and you probably won't get there without thoroughly stressing it (i.e. Furmark and Linpack/P95). Not counting the monitor, your idle should be well under 100W. I'd be picking around 50W.

You aren't going to be using full load for 8 hours a day.

It's quite difficult for software to measure power consumption of your computer, because there isn't really any communication with the PSU. You can't get things like fans, and most readings that do exist are very suspect.

However, some PSUs can screw with the measurements of cheap meters. The best way would be to turn everything in the house off (while no-one else is home) and see how fast the power meter is measuring.

Have you heard of any that come with software to keep a log of the power usage?
I worked it out based on 600w continuous, 8 hours a day, 365 a year... at £0.18 per KWh...
My GPU alone used a max of 250w... plus over clocked CPU, Corsair H80i, 4 Case fans, 2 monitors, I wanted to base it over everything running at full load continuously so I know what the maximum ill be using...?
