A mounting apparatus for a PCI card includes a mounting bracket, a mounting piece for attaching the PCI card to the mounting bracket, and a securing member. The mounting bracket has a base and a blocking plate bent from the base. The mounting piece includes an elongated body and a mounting end bent from the elongated body. The elongated body adjoins the base and the mounting end abuts on the blocking plate. The securing member includes a first pivoting portion pivotably attached to the mounting bracket, a pressing portion extending from the pivoting portion, and a securing portion extending from the pressing portion. The pressing portion elastically abuts against the mounting end, thereby sandwiching the mounting end between the blocking plate and the pressing portion. The securing portion is for driving the pressing portion to move away from the mounting end by handling the securing portion.
