Answer : It is subject to the history. In the early time (ca. 15 years ago) IBM had brought into the market the so-called “PS2- computers” (flat desktops) with special unique components and dimensions (like PS2 mouse, PS2 keyboard, PS2 cards for special PS2 slots as well as PS2 power supply). It was a flop, because the PS2 components were only available from IBM but not in the free common market. Anyway, the specified compact standards of PS2 form-factors and dimensions are kept and still be used up to nowadays (e.g. PS2 mouse, PS2 keyboard and also PS2 power supply). Note : PS2 power supplies have a defined standard specification in height and width (ca. 86mm x 152mm) as well as the placement of the 4 (four) holes of the screws for fixing, but the depth is varying and not exactly held by many manufacturers, e.g. PSU for industrial IPC or server applications.
