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. Furthermore, improper connection of USB header single wire connectors may eventually overload the overcurrent protection and cause damage to the board. 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 42) 40

Connectors and Headers
CAUTION
Only the following connectors and headers have overcurrent protection:
back panel
and 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.
Furthermore, improper connection of USB header single wire connectors may
eventually overload the overcurrent protection and cause damage to the board.
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 42)
