Two-port USB 3.0 header adapter

This BUCIER Y-splitter cable converts a single motherboard USB 3.0 header into two external USB 3.0 Type-A ports. It plugs into a standard 19/20-pin internal header and routes the connections to a front-panel bracket or slot. The 25 cm length suits typical chassis routing. The product is new and intended for internal PC assembly.

19-pin header with 20-hole connector

The cable’s internal connector carries 19 active pins while the shroud provides 20 holes, leaving one hole unused. This matches the standard USB 3.0 header layout found on most desktop motherboards. Backward compatibility with USB 2.0 and 1.0 devices is supported through the same ports.

Builders adding front-panel USB 3.0 ports

Suitable for system integrators and enthusiasts who need two front-access USB 3.0 sockets from one motherboard header. Not suited for users who require internal USB 3.0 device connections, longer cable runs, or a single-port header adapter.

Questions about this item

Will the 5 Gbps USB 3.0 speed hold up once the 25 cm cable is inside my case?

The 25 cm length keeps signal loss low, so the 5 Gbps USB 3.0 link runs at full speed in a typical chassis.

Does the 19-pin plug work with every 20-pin motherboard header?

Yes — the 19-pin connector fits the standard 20-pin USB 3.0 header; the extra hole on the board is simply unused.

What clearance do I need behind the expansion slot for the two Type-A ports?

The Y-splitter needs one standard PCI bracket cut-out; the 25 cm tails let you route the header plug to any motherboard USB 3.0 socket.
