1. A power supply system, be used to supply power to a load and comprising:
a system board comprising a first side and a second side disposed opposite to each other, wherein the load is disposed on the first side;
a substrate comprising a first side and a second side disposed opposite to each other, the first side of the substrate being located between the second side of the system board and the second side of the substrate;
at least one output capacitor surface-mounted on the second side of the system board;
at least one positive output conductive-connected region, disposed on the first side of the substrate, connected to the second side of the system board, and being electrically connected to one terminal of the at least one output capacitor via a wiring in the system board;
at least one negative output conductive-connected region disposed on the first side of the substrate, connected to the second side of the system board, and being electrically connected to other terminal of the at least one output capacitor via the wiring in the system board; and
at least one power unit disposed on the second side of the substrate, and being electrically connected to the at least one positive output conductive-connected region and the at least one negative output conductive-connected region via a wiring in the substrate.
