An example method for managing power within an imaging device includes: determining an interface of the imaging device via which the imaging device is receiving power; based on the interface, determining a power budget associated with the interface; determining which fixed load components of the imaging device are enabled; calculating a remaining power budget by subtracting a power consumption of the enabled fixed load components from the power budget; responsive to the remaining power budget being positive, configuring non-fixed load components such that a total power consumption of the non-fixed load components does not exceed the remaining power budget; and responsive to the remaining power budget being negative, providing, via a user interface, a notification of insufficient power budget.
