Description

Technical Field

[0001] This utility model relates to the field of power supply technology, and in particular to a PC power supply casing. Background Technology

[0002] Traditionally, PC power supply casings have mostly been top and bottom shells made of iron, with numerous screws and a predominantly square shape. Top and bottom shells require many screws for fastening, which is aesthetically unappealing. For consumer products, overly square casings don't look high-end or sophisticated. Furthermore, the iron casing doesn't provide much heat dissipation, especially under natural cooling conditions.

[0003] Therefore, it is necessary to provide a PC power supply housing that facilitates the overall assembly and disassembly of the product and provides greater heat dissipation. Utility Model Content
