  • Splits one 19-pin header into two USB 3.0 20-pin ports
  • 18AWG copper conductors deliver reliable power to both connections
  • Short 12cm length keeps cable routing tidy inside the case
  • Y-splitter design adds front-panel USB ports without extra headers
  • New cable ready for immediate motherboard installation

Internal USB 3.0 expansion

This BUCIER splitter adapts a single 19-pin motherboard header into two USB 3.0 20-pin connections. It suits builders adding front-panel ports or internal hubs where header space is limited. The 12 cm length keeps routing tidy inside compact cases.

Signal integrity under load

18AWG copper conductors maintain stable power delivery and data throughput when both downstream ports operate simultaneously. The short run minimises voltage drop across the Y junction, supporting sustained transfers without the signal degradation seen on longer, thinner cables.

Build and daily handling

Molded strain relief at each connector resists fatigue from repeated insertions during hardware swaps. The 19-pin plug seats securely in the motherboard header, while the dual 20-pin ends align with standard USB 3.0 front-panel or bracket connectors. Rigid 18AWG wires hold their shape for clean cable management behind the motherboard tray.

Questions about this item

Does the 18AWG cable run hot when the motherboard header powers two devices continuously?

The 18AWG copper conductors are rated for the current a USB 3.0 20-pin header delivers, so the 12 cm splitter stays cool during sustained dual-device use.

My motherboard only has a single 19-pin USB 3.0 header — is that all I need to run both ports?

Yes, the 19-pin plug connects directly to that header and the Y-split provides two USB 3.0 20-pin sockets for your front-panel ports or accessories.

Will the 19-pin plug work with an older 9-pin USB 2.0 header I still have on the board?

No, the 19-pin connector is keyed for USB 3.0 20-pin headers only and will not fit or function on a 9-pin USB 2.0 header.
