Vertical power supply system and manufacturing method of connection board

A vertical power supply system, comprising:

• a system board comprising a first surface and a second surface, wherein the first surface and the second surface are opposite to each other;
• a substrate comprising a third surface and a fourth surface, wherein the third surface and the fourth surface are opposite to each other, and the third surface of the substrate is located between the fourth surface and the second surface of the system board;
• a chip unit disposed on the first surface;
• a plurality of first capacitors disposed on the second surface;
• a plurality of connection boards, wherein each of the plurality of connection boards comprises a first end, a second end and a side wall, the first end and the second end are opposite to each other, the first end is electrically connected to the second surface of the system board, the second end is electrically connected to the third surface of the substrate, and the side wall is disposed between the first end and the second end in a surrounding manner;
• a plurality of third capacitors disposed on the side wall;
• and
• a power unit disposed on the fourth surface.
