A power supply system of a vehicle is provided. The system includes a high-voltage battery for storing power and a power relay that is disposed between the high-voltage battery and an electric load. A first converter receives the power from the high-voltage battery through the power relay and a second converter bypasses the power relay to directly receive the power from the high-voltage battery. The electric load receives the power from at least any one of the first converter and the second converter.
