asked on

ATX Front Panel Connector -What is Pin-9 5-volts?

This deals with the Front Panel Connector
Intel DZ68DB motherboard..
CM Storm case

Connector on motherboard has 9 pins. I understand the connections from the case to pins 1-8. Those handle HD LED, reset switch, Power LED, an on/off switch.

But what is pin-9? It says Power 5 volts. What connects to pin-9? Is it a lead from the power supply? From the case? I don't see anything coming from the case. Seems like it should be simple, but I'm stumped. Thanks.

>> Actually 5v is one of the main rails on your power supply...

Sloppy reply on my part.
I meant something run off voltage from the front panel header.   {sheepish grin}

Well, I assembled the computer with nothing on pin-9 and it works fine.  I wasn't sure about the pin, and the 5 volts concerned me. So I thank you folks for the advice.
Thanks for the feedback and the Points.    : )
