Abstract:
1. A compact server power supply having high power density, comprising: a casing; a main printed circuit board mounted inside the casing and having two opposite short sides and a trace layout thereon, wherein the trace layout has trace wires, a first trace patterns of high voltage potential and ground; a sub-printed circuit board vertically mounted on and soldered to the main printed circuit board; a power supplying circuit having at least one primary side circuit unit, at least one transformer and at least one secondary side circuit unit, wherein electronic elements of the at least one primary side circuit unit, the at least one transformer and electronic elements of the at least one secondary side circuit unit are soldered on the main printed circuit board, except parts of the electric elements of the secondary side circuit unit are soldered on the sub-printed circuit board; a power output terminal set mounted on one short side of the main printed circuit board and soldered to the trace pattern of a high voltage potential and the trace pattern of ground; and at least one fan mounted on the other short side of the main printed circuit board.
