Purpose & Audience

This BUCIER adapter connects two external USB 3.0 Type-A male headers to an internal 19-pin motherboard header. It is built for PC builders who need front-panel USB 3.0 connectivity on boards that only expose external ports.

Build Integration

The male-to-male cable plugs directly into the board's 20-pin header and the case's front-panel ports without tools. It brings USB 3.0 functionality to first-generation USB 3.0 motherboards lacking an internal header. On USB 2.0 boards the same ports operate at 2.0 speeds.

Sustained Operation

Copper conductors carry data at up to 5 Gbps during continuous transfers. The plug-and-play design supports hot-swapping, so devices can be attached or removed while the system runs without interrupting the connection.

Questions about this item

Will the 5 Gbps link hold under sustained transfers or does the cable itself throttle?

The adapter is rated for 5 Gbps; sustained throughput will depend on the host controller and the drives attached.

Does the adapter generate noticeable heat or draw extra power when left connected all day?

It is a passive copper cable with no active electronics, so it adds negligible heat or power draw during continuous use.

My motherboard only has a 19-pin internal USB 3.0 header — what else do I need to make this work?

You need a case with front-panel USB 3.0 ports wired to a 19-pin internal cable; the adapter then connects that cable to two external Type-A plugs.
