A mounting apparatus for PCI card, includes a mounting bracket, a securing piece adapted to attach the PCI card to the mounting bracket, and an elastic securing member pivotally mounted on the blocking plate of the mounting bracket. The mounting bracket has a base and a blocking plate perpendicular to the base. An opening is defined in the mounting bracket adjacent to the blocking plate. The securing piece includes a first end and a second end perpendicular to the first end. The first end abuts and engages with the mounting bracket base, and the second end abut the blocking plate of the mounting bracket. The elastic securing member includes a pressing portion and an actuating portion. The actuating portion is resiliently received in the opening to force the pressing portion to sandwich the second end of the securing piece between the blocking plate and the pressing portion.
