2.7 Connectors
CAUTION
Only the following connectors have overcurrent protection: back panel USB, front
panel USB, and PS/2.
The other internal connectors and headers are not overcurrent protected and should
connect only to devices inside the computer’s chassis, such as fans and internal
peripherals. Do not use these connectors or headers to power devices external to the
computer’s chassis. A fault in the load presented by the external devices could cause
damage to the computer, the power cable, and the external devices themselves.
This section describes the board’s connectors. The connectors can be divided into
these groups:
• Back panel I/O connectors
• Component-side I/O connectors and headers (see page
59)

digital audio output connectors), described on page
