The 48 stepper motors plus all the microcontroller circuit needs between 1.0 and 1.2 A (5V), or around 25 mA per motor, so not that much. I agree that stepper motors are usually power hungry, but these are small torque/low power motors designed for automotive dash boars. The power needed is more of a problem with powering on the whole system, as the condensators and circuit needs more current compared running the motors.
