Many of us have been curious on the power consumption of our systems. I purchased a Kil-A-Watt meter and hooked it up last night.

On this circuit test I have the following

6 PCs (Power Supply info below)
4 PSU 500w
1 PSU 300w
1 PSU 650w

4 LCD 17” monitors
2 LCD 22” Wide screen monitors

Misc:
Router
Hub
Wireless devices (Mouse charging units)


Here are my results.

Turning everything at once it spiked at 1280W

Consistent run time it was steady at around 950W – 1000W

I let the meter run for 4 hours. It came out to .38KWH an hour. I’m totally surprised the number is this low! I figured twice that.
