2.7 megawatts of electrical power! It's running the computers, the gimbal actuators and the flaps. Anything else?
Mostly flaps. They need to apply a lot of torque at a high speed, which means lots of power.

2.7 MW isn't really that much, though, except for the fact that it's electric power. Each Raptor turbopump puts out 75 MW of shaft power, and each Raptor combustion chamber puts out 7,000 MW of thermal power.

During boost, Starship's thermal power output is roughly equal to half the entire United States' average electric generation power output.
