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 or 1394 header single wire connectors may eventually overload the overcurrent protection and cause damage to the board. 3 V -12 V Ground PS-ON# (power supply remote on/off) Ground Ground Ground No connect +5 V +5 V +5 V (Note) Ground (Note) Note: When using a 2 x 10 power supply cable, this pin will be unconnected. 4 Front Panel Header This section describes the functions of the front panel header. Table 18 lists the signal names of the front panel header. Figure 12 is a connection diagram for the front panel header.
