Form Factor Overview

This specification allows the processor, chipset, memory, add-in cards, and other components to be designed and located in a way that facilitates both efficient motherboard routing and cooling of the components. It also allows options for system layouts that can accommodate a range of profiles and sizes from compact systems and devices to large, very expandable systems.

The power supply connectors and interfaces are defined to be compatible with those defined for the ATX family of form factors. For more information on standard power supply definitions and the ATX form factor family, refer the references listed in Additional Information.

The following figure shows three example of the many layouts possible with the BTX form factor.
