A modular edge power system is provided. The modular edge power system includes a housing having a rack adapted to mount compute devices and a direct current power bus within the housing. Multiple power distribution units are adapted to be removably coupled to the direct current power bus at a position within the housing and outside of the rack. Each power distribution unit is configured to distribute electrical power received from the direct current power bus to one or more compute devices mounted in the rack. Each power distribution unit may convert the electrical power from a first power level to a second power level.
