A mounting apparatus for a PCI card includes an enclosure, a mounting bracket, a securing bracket mounted in the enclosure, and a securing member slidably mounted on the securing bracket. The mounting bracket secures a first terminal of the PCI card. The securing bracket includes a main body and an elastic piece extending from the main body. The elastic piece comprises a piece body and a securing protrusion. The securing member includes a pressing panel and a securing portion extending from the pressing panel. The securing member slides relative to the main body to enable the securing protrusion to engage with the securing portion and enable the pressing panel to press a second terminal of the PCI card.
