I was curious about the power consumption of my Indigo2 Solid Impact computer, so I bought a watt meter and measured the wattage of this computer. I found after bootup in idle my power consumption was 175 watts. This was higher than data reported below for a similar system. I pay 31cents per kwh, so my monthly cost to keep this machine up and running 24h is about $40.  SGI depot web site had a post giving the following data for various SGI computers. Feel free to post your measurements if you have taken them. See attached table

The Impact graphics is pulling more power than the Extreme -- there's a different power supply involved... that might explain your variance.

Well the sgi depot list of power consumption also does not have an Indigo2 system identical to mine for a direct comparison. That is why.
