Computer Motherboard Front Panel Pinouts

If you buy a new computer motherboard it usually comes with a user manual. There you should able to find the front panel header pinout for the motherboard. You may have trouble when changing the computer’s casing if you lost the manual. Because the pinout usually is not printed on the board. Not all motherboards use the same front panel header pinout, you can search the Internet but it may be hard to find the correct pinout if the motherboard is not a common model. I had such bad experience so I decided to write this post for all the front panel connector diagrams that I ever used.

Computer front panel header is where the connectors of casing cables (reset button, power on/off button, power on light and hard disk activity light) and the motherboard are connected. Sometimes it includes speaker connector. But front USB, front audio, card reader are not included in this header because they have their own connectors.

Front panel header has many names:

  • Front Panel Connector
  • F_Panel
  • JPanel
  • JFP1

Computer front panel usually has these pins:

  • POWER or POWER SW or ON/OFF
  • RESET or RESET SW or RST
  • MSG or POWER LED or POW LED or PLED
  • HDD or HDD LED or HLED
  • SPEAKER or SPK
  • CI (chasis intrusion)
  • +5V or NC (not connected) or RSVD (reserved) or DUMMY

On the diagrams below, the white text numbers mean there is no pin on the position.
