The specification mandates specific mounting hole patterns that align with mid-tower and full-tower cases, ensuring a secure fit that prevents flexing and stress on solder joints. Power Supply Integration A cornerstone of the ATX standard is its integration with the power supply unit (PSU), which utilizes a 20-pin or 24-pin main connector to deliver stable power to the motherboard.
ATX Standards Component Layout and Key Specifications
The design allows the power supply to remain partially outside the main airflow path, with a dedicated intake fan that draws cool air directly from outside the case. MicroATX reduced the board size to 9.
Conversely, Extended ATX (E-ATX) expanded the width to 12 inches to accommodate additional memory channels and PCIe lanes for high-end workstations and server motherboards. 6 inches by 9.
