4.1 Signal Tables for the Connectors and Headers
CAUTION
Only the following connectors and headers have overcurrent protection: back panel USB Type A
and Type C, front panel USB, internal USB headers, internal power header, and DC Vin jack.
All other 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 system.
