Product Overview

The BUCIER USB 3.0 Header Splitter converts a single 19/20-pin motherboard header into two female connectors using a 6-inch flexible cable. It supports 5 Gbps data rates and maintains backward compatibility with USB 2.0 devices. The compact design suits tight chassis layouts where internal USB expansion is needed without additional brackets.

Who It Suits

Builders adding front-panel USB ports or internal hubs to boards with only one header will find this adapter practical. It works well for SLI setups requiring extra USB 3.0 connections. Users needing more than two ports or requiring external Type-A and Type-C combinations should consider alternative expansion solutions.

Capacity and Limits

The splitter handles two simultaneous USB 3.0 devices at full 5 Gbps throughput per port thanks to full-duplex signalling. Bandwidth is shared across the single upstream header, so sustained heavy transfers on both ports may reduce individual speeds. The 26 AWG wiring and short length keep signal integrity high for typical internal peripherals.

Questions about this item

Does my motherboard need a 19/20-pin USB 3.0 header for this splitter?

Yes, the splitter plugs into a single 19/20-pin USB 3.0 header on the motherboard and provides two male 19/20-pin connectors for front-panel or internal devices.

Will this splitter work with USB 2.0 headers on my older motherboard?

No, the splitter is designed for USB 3.0 19/20-pin headers only; it does not fit USB 2.0 9-pin headers.

How can I confirm the splitter is delivering 5 Gbps after installation?

Connect a USB 3.0 device, then check the operating system’s device manager or a benchmark tool to verify the link is running at SuperSpeed 5 Gbps.
