ABSTRACT:
A power supply unit (PSU) has walls which define an internal volume of the PSU. A metal sheet forming left and right side walls and an upper wall is provided with plural perforations on each of those walls. The perforations are circular in shape, and formed in a regular grid pattern. The perforations are formed by punching the metal sheet before it is bent into shape. The perforations in the housing of the PSU allow hotspots to be carried through the walls of the housing of the PSU, following which the hotspots are unable to damage internal components of the PSU. This allows the use of reduced flow rate fans.
