We don't publish an average power consumption figure. The product Hardware Datasheet specifies a maximum power figure of 1000W for X3, X2 and X1 (all three models have the same power supply). The actual consumption at any time will be dependent on a great many factors so it is not possible to provide an average value for you. You may well indeed be seeing a much lower value than 1000W reported in the Syslog in tests you are doing at the moment. We would advise provisioning for the value given in the datasheet to allow for the possibility that future software updates will change the performance of the hardware and result in a corresponding change in power consumption.
