Expanded 9-pin USB motherboard header hub - Key benefit: Increases internal USB capacity with 4 USB 2.0 ports from a single 9-pin motherboard header, freeing more front panel and PCIe connector options for your build. - Stable power: The hub uses a SATA power connection to provide a reliable, stable power source for connected devices. - Easy setup: Plug-and-play installation with user friendly setup. No complex configuration required. - Safe design: Built to prevent short circuits and accidental disconnections. The hub helps protect the motherboard, pins, and case from short circuit risk when the header or board is moved or adjusted. What this product does for you - Adds four internal USB 2.0 ports using a single 9-pin USB motherboard header, expanding compatibility for devices that rely on internal USB connections. - Keeps devices powered with a dedicated SATA power input, reducing the chance of USB power fluctuations. - Simplifies cable management in compact or crowded builds by consolidating USB connections away from the motherboard header. - Provides protection against accidental removal or short circuits, helping maintain system reliability. Compatibility and installation - Compatible with standard 9-pin USB motherboard headers. Connects to the header and supplies power through a SATA power connector. - Plug-and-play operation means you can install without special tools or drivers. Suitable for typical PC builds that require extra USB connections inside the chassis. Key attributes - Function: Internal USB hub with 4 USB 2.0 ports via 9-pin header; SATA powered. - Compatibility: Designed for standard motherboard USB headers and internal USB devices. - Power: SATA power connection provides stable power for connected devices. - Protection: Short circuit and accidental disconnection protection to safeguard motherboard, pins, and case. Practical use scenarios - Scenario 1: Expand USB access for internal components in a compact or HTPC build. Use the 4 USB 2.0 ports to connect a WiFi receiver, RGB controller, or other internal USB devices when motherboard headers are fully utilized. - Scenario 2: Improve cable management in small form factor systems. Route USB devices away from the motherboard header to a more accessible internal location while keeping power stable via the SATA connection. - Scenario 3: Upgrade or maintenance tasks. Temporarily reallocate USB devices that would otherwise share limited headers, making it easier to swap hardware such as a USB-based lighting controller or other internal peripherals without pulling cables from the motherboard. Notes - This product is designed for internal PC builds and relies on the motherboard 9-pin USB header plus a SATA power connection. - For best results, ensure correct orientation when connecting the 9-pin header to avoid bent pins or misalignment. No drivers are required; it operates as a plug-and-play hardware interface. This description preserves the original specifications and functionality: 4 internal USB 2.0 ports, 9-pin USB motherboard header splitter, SATA power connection for stable power, plug-and-play installation, and protection against short circuits and accidental disconnections. It highlights practical benefits, clarifies usage, and provides concrete scenarios to demonstrate real-world application.
