InLine USB 3.0 Adapter internal 2x USB A female to mainboard header

The InLine USB 3.0 Adapter internal 2x USB A female to mainboard header provides two external USB A female ports via a 19‑pin motherboard connector. Designed for internal installation, the adapter features nickel‑plated contacts and a black-and-blue housing to integrate into PC builds and expand available USB 3.0 connectivity while supporting high-speed data transfer.

Advantages

The adapter offers a compact internal solution to add two USB A female ports directly to the motherboard header without additional brackets. Nickel‑plated contacts improve corrosion resistance and connection reliability. The cable and connector are compatible with standard 19‑pin USB 3.0 headers and maintain the SuperSpeed signal pathways required for USB 3.0 performance.

Suitable for

• Adding two external USB A ports to a desktop PC via an internal 19‑pin header
• Upgrading or repairing front-panel USB connectivity

How to use

Power off the PC and disconnect it from mains. Locate the motherboard’s 19‑pin USB 3.0 header, align the adapter’s connector with the header pins and press gently until fully seated. Route the cable to the desired mounting location and secure the external USB A female ports in the case front or expansion area as required. Reconnect power and boot the system; the operating system should detect the additional USB ports automatically.

Recommendations

Ensure the motherboard header matches the adapter’s 19‑pin USB 3.0 layout before installation. Avoid forcing the connector at an angle to prevent bending pins. For stable SuperSpeed performance, use shielded internal routing and keep the cable away from high-power or noisy components.
