19-Pin USB 3.0 Header to Dual USB 2.0 Adapter

This adapter converts a single motherboard 19-pin USB 3.0 header into two standard 9-pin USB 2.0 connectors. It uses an integrated USB 2.0 hub chipset to provide the split without altering signal properties. The device is transparent to the operating system and requires no software drivers to function.

Suited for builders adding front-panel USB 2.0 ports

It suits builders who need extra USB 2.0 ports on a chassis that only offers a USB 3.0 header. Each port delivers up to 500 mA at 5 V and runs at 480 Mbps. Builders who require full USB 3.0 throughput on both ports should look elsewhere, as this adapter is limited to USB 2.0 speeds.

Check header keying and clearance before ordering

Verify that your motherboard has an available 19-pin USB 3.0 header with the correct keying for the adapter plug. Ensure there is enough physical space around the header for the adapter body and the two 9-pin cables. Confirm your front-panel cables use standard 9-pin USB 2.0 connectors.
