A modular DC power distribution system. A physically discrete input conversion module is utilized for converting a source AC signal to a high voltage DC signal. Multiple universal mounting sites are provided in a power supply backplane for engaging one or more of such input conversion modules. Within the power supply backplane, the high voltage DC signal is delivered to a DC distribution bus. A physically discrete DC step-down module is utilized for converting the high voltage DC signal from the DC distribution bus to a point-of-load DC signal distributable to application boards. The power supply backplane includes multiple universal mounting sites wherein one or more DC step-down modules may be installed or removed. In another embodiment, the DC power distribution system of the present invention includes a pre-charge system for permitting the input conversion modules and the DC step-down modules to be hot plugged into the power supply backplane.
