Single-header to dual-header adapter

The BUCIER USB 3.0 adapter splits one motherboard 19/20-pin header into two female 19/20-pin ports. It lets builders connect two front-panel USB 3.0 devices, hubs or card readers from a single internal header. The copper construction carries the signal without an active controller. It is aimed at PC builders who have only one USB 3.0 header but need two internal connections.

Passive thermals and SATA auxiliary power

The splitter is a passive PCB so it adds no fan noise and draws negligible power from the header itself. A SATA power cable supplies the extra current needed when both downstream ports run devices simultaneously. The board stays at ambient case temperature during normal file transfers. No software or driver is required for the power arrangement.

5 Gbps USB 3.0 bandwidth shared across two ports

The adapter is rated for USB 3.0 5 Gbps signalling, which is 10 times the throughput of USB 2.0. Both ports share the single upstream 5 Gbps lane, so simultaneous heavy transfers will split that bandwidth. Buyers who need dedicated 5 Gbps per device cannot get it from this splitter.

Questions about this item

How do I install the BUCIER adapter to split one motherboard 19/20-pin header into two front-panel ports?

Plug the single 19/20-pin male connector into the motherboard USB 3.0 header, attach both female 19/20-pin headers to your front-panel cables, then connect the included SATA power lead to a drive power cable for stable 5 Gbps operation.

What maintenance will the BUCIER splitter need over time?

No scheduled maintenance is required; simply reseat the header connectors and check the SATA power plug if a front-port device stops enumerating at 5 Gbps.

What limit appears first when both front-panel ports run sustained transfers?

The single motherboard 19/20-pin host link caps combined throughput at 5 Gbps, so simultaneous heavy traffic on both ports will share that bandwidth.
