Abstract: A power supply assembly includes an enclosure body, a cover panel mounted to the enclosure body, a power supply, and a positioning element mounted to the cover panel. The enclosure body includes a bottom panel, a rear panel substantially perpendicular to the bottom panel, and a side panel substantially perpendicular to the bottom panel and the rear panel. The power supply assembly is mounted in the enclosure body and is prevented from moving in a first direction, that is substantially perpendicular to the rear panel, and a second direction, that is substantially perpendicular to the side panel, and disposed between the bottom panel and the cover panel. The positioning element includes a first ladder-shaped positioning tab abutting two adjacent surfaces of the power supply and preventing the power supply assembly from moving in a third direction, that is substantially perpendicular to the cover panel and the second direction.

Abstract: A mounting assembly includes a fan and a plate. The fan includes a number of locking pins. The plate defines a ventilation area corresponding to the fan. A number of securing holes are defined by the plate adjacent to a corner of the ventilation area. Two or more raised blocks are located on the plate and adjacent an edge of the ventilation area. The locking pins of the fan are slid into the securing hole and at the limit of the securing hole the raised blocks abut an edge of the fan to prevent the fan moving back out of the securing hole.
