USB 19-pin to USB 9-pin adapter cable 0.15 m, black, No name ZUUS-173

The USB 19-pin to USB 9-pin adapter cable (0.15 m) is an internal computer wiring accessory designed to convert a motherboard's 19‑pin USB header into a standard 9‑pin USB connector. Its compact 15 cm length and black jacket make it suitable for tidy routing inside PC cases, allowing front-panel USB ports or internal USB devices to be connected when a 9‑pin connection is required. The adapter provides a simple, reversible wiring solution without altering motherboard headers or device connectors.

Advantages

This adapter cable offers a compact and low-profile connection that simplifies internal cable management in desktop systems and small form-factor builds. The fixed 0.15 m length reduces excess cable slack and helps maintain airflow inside the chassis. The black insulation provides discreet appearance and compatibility with most case interiors. The cable preserves standard USB pin assignments to ensure compatibility with front I/O panels, internal card readers and similar devices.

Suitable for

• Connecting front-panel USB ports to a motherboard with a 19‑pin header when the device uses a 9‑pin connector
• Internal card readers and bay devices that require a 9‑pin USB cable
• Small form-factor PCs and compact builds where short internal cables are needed
• Upgrading or reorganising cable layouts to reduce clutter and improve airflow

Key specifications

• Cable type: internal adapter cable
• Input connector: 19‑pin motherboard USB header (internal)
• Output connector: 9‑pin USB connector (internal)
• Length: 0.15 m (15 cm)
• Colour: black
• Usage: internal PC connections for front I/O and devices

How to use

Power off the computer and disconnect it from mains before installing the adapter. Locate the motherboard's 19‑pin USB header and align the adapter's 19‑pin plug according to the header's keyed orientation. Connect the 9‑pin end to the device or front-panel cable that requires a 9‑pin connector. Ensure connectors are seated firmly but do not force them; check pin alignment to avoid bending pins. After installation, close the case and restore power to verify USB ports and devices function correctly.

Recommendations

Use the adapter only for internal, low-voltage USB connections inside a properly grounded chassis. Avoid sharp bends and kinking of the cable, and keep it away from moving parts such as fans. If a device still fails to operate after installation, verify pin alignment and test with an alternative internal USB cable to isolate the issue.
