Pinout label on USB mobo connector

[cgrue]

I have a connector on my mobo for USB 2.0, It lists 2 pairs of pins like
5V, 7-, 7+, GND and 5V, 8-, 8+, GND

Then it shows a single pin at the end of the connector labeled NC.

One my USB from panel connector I have 2 sockets matching the 2 pair of pins on the mobo USB connector. Then there is a single wire in the same bundle from the fron panel USB socket with the 2 connectors that is labeled GND. Does the single wire from teh front panel socket that is labeled GNDgo on the mobo pin labled NC?

Thanks,
Charles

I believe that the label NC stands for No Connection.

Your USB header pinout on the motherboard should have 9 pins and one blank pin space per header

X X X X O
X X X X

I presume the "NC" pin is the one at the end of the top row (marked "O") - you do not need to connect the single wire to this pin- as you pointed out NC stands for no connection. The extra black wire from your case is a shield ground that you would use with a different type of USB header. So you only need to attach the 2 four pin blocks.
In the diagram layout above your pin blocks correspond with
5v, USB-, USB+, GND, and NC (unattached)
5v, USB-, USB+, GND

No Connection

Thank you for the reply. That NC pin was worrying me quite a bit. I didn't want to power up the new machine just to damage the motherboard. I couldn't be sure what the NC label meant.

Thanks!
