OULLX Motherboard USB 9-Pin to 19-Pin / 20-Pin Header Splitter Extension Cable Adapter

Upgrade your PC case's front panel USB ports without replacing your motherboard.

Frequently Asked Questions

Q: Will this USB 9-pin to 19-pin adapter work with my motherboard?

A: Yes — this adapter is compatible with any standard motherboard that has a USB 2.0 9-pin internal header. It allows you to connect a PC case front panel with a 19-pin or 20-pin USB 3.0 connector to your board's 9-pin port. Note that transfer speeds will operate at USB 2.0 rates.

Q: What is the difference between the two available versions?

A: The two versions differ by connector orientation. The 19-Pin Male to 9-Pin Female version plugs the 19-pin side into the case front panel's male connector, while the 19-Pin Female to 9-Pin Male version is designed for the opposite configuration. Select the version that matches your specific case front panel and motherboard connector types.

Q: Does this adapter support USB 3.0 transfer speeds?

A: No. While this adapter physically converts a 9-pin USB 2.0 header to a 19-pin/20-pin connector, the data transfer speed is limited to USB 2.0 (up to 480 Mbps) since it connects to the USB 2.0 header on the motherboard. It does not enable USB 3.0 SuperSpeed transfers.

Q: Is any installation software or assembly required?

A: No — this is a fully plug-and-play adapter. No drivers, software, or assembly are required. Simply connect it to the appropriate headers inside your PC case and you're ready to go.
