This internal PCBA splitter hub acts as a practical motherboard header expansion adapter, supporting input from either Type-E port or 19/20Pin USB 3.0 motherboard header. It splits one original internal connector into two separate female ports: standard USB 3.0 20Pin and Type-E, allowing you to install two different front panel USB accessories at the same time. Built with USB 3.0 5Gbps transmission standard, it maintains fast and stable data transmission for flash drives, card readers and other USB devices. Adopting lightweight bare PCBA board construction, it features a tiny footprint that fits neatly inside all ATX, MATX and ITX computer cases with no bulky casing. No driver installation is required for plug-and-play operation, fully compatible with Windows and Linux desktop systems. It is an essential DIY accessory for PC assemblers, hardware enthusiasts and custom workstation builders to expand internal front-panel USB resources conveniently.
