To distribute a DC power supply voltage suitable for an apparatus via a single power supply wiring.
This power supply voltage feed system includes: a DC voltage feed section which outputs the DC power supply voltage; a power supply feed connecting section, to which the DC power supply voltage from the DC voltage feed section is given via the power supply wiring, and which feeds the DC power supply voltage to a power-receiving section of the apparatus; a power supply information acquiring section which is arranged at the power supply feed connecting section, and reads power supply information held by the power-receiving section of the apparatus; and a voltage conversion section which is arranged at the DC voltage feed section, to which the power information read by the power supply information acquiring section is transmitted, and which sets the voltage value of the DC power supply voltage outputted by the DC voltage feed part, on the basis of the power supply information.
