USB-hub DELOCK 5 Gbit/s 20-pins header naar 2× USB-A 5 Gbit/s

The DELOCK USB hub converts a 20‑pin motherboard/header connector into two external USB‑A ports that each support data rates up to 5 Gbps. Intended for internal desktop PC installation, the hub provides two accessible USB‑A sockets for connecting high‑speed peripherals without occupying rear or front panel connectors. The compact adapter is designed to fit inside a computer case and to work with standard 20‑pin internal USB headers present on many modern motherboards.

Advantages

This adapter offers two high‑speed USB‑A ports while using a single 20‑pin internal header, enabling connection of USB flash drives, external HDD/SSD enclosures, input devices and other peripherals at up to 5 Gbps per port. Its internal design keeps external cabling neat and avoids the need for additional external power in most typical desktop setups. The plug‑and‑play nature makes installation straightforward when compatible headers are available on the motherboard.

Suitable for (tasks / use cases)

• Adding two external USB‑A ports to a desktop PC with an available 20‑pin internal USB header
• Connecting high‑speed storage devices such as external SSDs or flash drives
• Providing convenient ports for keyboards, mice and other USB peripherals
• Expanding internal-to-external connectivity in small-form-factor or custom builds

Key specifications

• Interface: internal 20‑pin motherboard/header to 2× USB‑A
• Transfer speed: up to 5 Gbps per port (USB 3.x performance class)
• Number of external ports: 2 USB‑A ports
• Installation: internal desktop PC connection inside the computer case
• Power: operates from motherboard header; no external power adapter required in standard configurations

How to use

Install the adapter inside the PC case by connecting its 20‑pin connector to the corresponding USB header on the motherboard, ensuring correct orientation of the connector. Route the two external USB‑A sockets to a suitable location on the case or bracket where devices can be plugged in. After connection, power on the system and allow the operating system to detect the new ports; most modern OSes will enable the ports automatically without additional drivers. Use standard USB cables and devices to connect peripherals and storage media to the external USB‑A ports.

Recommendations

Verify that the motherboard has a compatible 20‑pin internal USB header and that the header supports USB 3.x signals to achieve the full 5 Gbps speed. Avoid forcing the connector; align pin 1 markings to prevent misconnection. For power‑hungry devices, consider connecting them to dedicated powered ports or hubs, as the internal header delivers standard motherboard power levels.
