ATX form factor
The ATX form factor has been defined to address four major areas of
improvement required of today’s predominant form factors.
Enhance PC ease-of-use with all built-in I/O connector
Better support for current and future I/O
Redude total system cost
Better support for future processor technology
ATX is an evolution of the popular Baby-AT form factor. By mounting the
power supply on its side, the processor is relocated away from the expansion
slots, and the longer side of the board is used to host more on-board I/O
connector; this placing of I/O on the board reduces cabling inside the box,
lower costs, and improves reliability and ease-of use. A flexible I/O panel
allows ATX to support all current and future I/O requirements. The ATX
power supply will directly suck the air out of chassis that will save the cost of a
secondary fan in the system. System cost is further reduced by the higher
integration of PC components onto the system board itself, saving materials,
inventory holding, and assembly cost.
