I had the computer set up and it was showing fairly steady power consumption of around 220 watts. Again a little less than I expected. Turning off my smaller monitor drops the consumption by 19 Watts (s/b 34 Watts), the larger monitor by about 26 Watts (s/b 55 Watts).
I’m going to disengage the power meter now since I want to reconfigure things a bit as I swap in my new modem/router combo from AT&T. I’m going to hook it up to some known consumer (a light bulb) to verify if the consumption readings are accurate.
Assuming accuracy, my main computer’s consumption after 273 hours (a little over 11 days) is 51 kilowatts or $5.42. The average cost is about 47 cents per day or $3.33 per week. The predicted annual cost is about $173 per year. A bit of an eye opener really. Little things have so much power to add up when paired with the inexorable march of time.
