2Pcs USB 2.0 9Pin Header Y Splitter Cable, Motherboard 9-Pin to Dual 9Pin Extension Cord, Internal HD Audio & USB Expansion Cable for PC, Black

This pack contains 2 pieces of black internal 9Pin Y splitter cables, designed for desktop motherboards with standard 9Pin USB 2.0 or HD Audio front panel headers. If your motherboard only provides limited built-in 9Pin ports, this splitter perfectly solves the shortage of internal connectors for additional front USB ports, audio jacks and fan control modules.

The cable adopts a 1-input to 2-output split structure. One end connects to the 9Pin header on your motherboard, while the two split terminals can be connected to different front panel modules. It supports standard USB 2.0 signal transmission and HD audio signal transfer for PC front panel audio jacks.

Constructed with durable copper wire and multi-layer insulating outer casing, the cable features excellent anti-interference performance to prevent signal distortion, static noise and unstable USB recognition. The firmly fitted connectors avoid loose contact caused by vibration inside the chassis during long-term operation.

Flexible cable body supports tidy internal cable routing, helping optimize airflow arrangement inside your computer case. Installation is plug-and-play without any driver or software configuration.

Important Reminder: Please verify the pin definition before wiring. Do not mix USB 2.0 9Pin headers and HD Audio 9Pin headers; mismatched connection may cause hardware failure. This splitter is suitable for internal chassis connection only, not for external peripheral devices. Ideal for PC builders, custom chassis modification and multi-front-panel setup projects.
