1. A power supply system installable in a predetermined apparatus to receive power supply from an external power system, the power supply system comprising:
a first power supply path configured to supply power to a plurality of load devices in the predetermined apparatus;
a first power converter configured to receive power input from the external power system, convert the power to first power, and output the first power to the first power supply path;
a second power converter connected to the first power supply path, the second power converter being configured to convert the first power to second power and output the second power;
a load power supply path separate from the first power supply path, the load power supply path being configured to receive the output second power;
a plurality of power supply devices connected to the load power supply path, the plurality of power supply devices being configured to receive input of the second power, convert the second power to load power, and supply the load power to each of the plurality of load devices; and
a power supply unit including the second power converter, the load power supply path, and the plurality of power supply devices,
wherein the power supply unit is configured to unitize the second power converter, the load power supply path, and the plurality of power supply devices so that the plurality of power supply devices are connected to the load power supply path in a predetermined relationship.
