The estimated typical power for an 1800 maximum configuration (3+0 clique with two TMS nodes, and three disk arrays) is approximately 7.2 kW in normal operation.
The actual power consumption levels for a particular configuration may be different depending on many factors such as the hardware configuration of each chassis, the applications running at the time of measurement, and the operating temperature.
