USB 3.0 20-pin to USB 2.0 9-pin adapter

This pack contains two adapter cables that convert a motherboard 20-pin USB 3.0 header to a standard 9-pin USB 2.0 connection. Each cable features male and female ends for flexible internal routing. They allow older front-panel ports or accessories to work with newer header layouts.

Buyers needing direct 20-pin USB 3.0 passthrough

These adapters step the signal down to USB 2.0 speeds, so they do not suit builds that require full 3.0 throughput from the front panel. Users without a spare 9-pin header on their board cannot use them. The pair is intended for internal case wiring only.

Questions about this item

Will the 20-pin USB 3.0 connector work with my existing 9-pin USB 2.0 motherboard header?

Yes, the adapter converts the 20-pin USB 3.0 male or female connector to a 9-pin USB 2.0 female or male header, letting you connect newer front-panel ports to an older board.

How can I verify the adapter is functioning correctly once installed?

Plug a USB 2.0 device into the front-panel port; if the device is recognised and transfers data at USB 2.0 speeds, the 20-pin to 9-pin conversion is working as intended.
