Akasa USB 3.1 Internal Extension Cable, 40cm, Female to Male Motherboard Header

Product Overview

The Akasa USB 3.1 Internal Extension Cable, model EXUSBI-40, is a compact yet versatile solution designed to extend the reach of your motherboard’s internal USB header. Measuring 0.4 m (40 cm), this cable bridges the gap between the motherboard’s internal connector and an external USB port, enabling easier access to peripheral devices without compromising on performance or aesthetics.

Key Specifications

• Connector Type: Female to Male – connects a 4‑pin USB header on the motherboard to a standard internal USB connector.
• Length: 0.4 m (40 cm) – short enough for tight builds yet long enough to reach most rear panel ports.
• Color: Black – blends seamlessly with typical motherboard and case interiors.
• USB Version Compatibility: Supports USB 2.0, ensuring reliable data transfer rates up to 480 Mbps.
• Build Quality: Durable copper conductors wrapped in high‑quality insulation for stable signal integrity.

Design and Construction

The cable’s construction prioritizes both signal fidelity and physical durability. Each of the four wires is individually shielded, reducing electromagnetic interference that could otherwise degrade USB performance. The connectors feature a robust locking mechanism to secure connections against accidental dislodgement during system operation.

Installation Guide

1. Locate the Internal USB Header: On most motherboards, this is a small 4‑pin socket near the rear I/O panel. Refer to your motherboard manual for exact positioning.
2. Insert the Female Connector: Align the cable’s female end with the header and gently push until it clicks into place.
3. Connect the Male End: Attach the male connector to an available internal USB port or a compatible adapter that routes to the rear panel.
4. Tidy Up: Use cable ties or Velcro straps to secure excess length, ensuring airflow is not obstructed.

Compatibility Overview

This extension cable is engineered for broad compatibility across a range of motherboard models that feature standard USB 2.0 headers. It works seamlessly with:

• Intel and AMD desktop motherboards (e.g., Z590, B550).
• Mini‑ITX and micro‑ATX builds where space constraints often limit direct header access.
• Custom water‑cooling or cable management setups that require extended reach to rear panel ports.

Performance Considerations

While the cable is rated for USB 2.0, its high‑quality construction ensures minimal signal loss even at maximum data rates. Users have reported consistent performance with peripherals such as external hard drives, keyboards, and mice when using this extension in both standard and overclocked systems.

Use Cases

• Gaming Builds: Allows gamers to position high‑end peripherals closer to the front of the case for ergonomic comfort.
• Workstations: Facilitates easy connection of external storage devices without opening the case during operation.
• Home Theater PCs: Enables clean cable routing in compact enclosures, keeping the rear panel tidy.

Maintenance Tips

To preserve optimal performance:

• Avoid bending the cable beyond its rated flexibility; gentle curves are acceptable.
• Keep connectors free from dust by using compressed air before and after installation.
• Inspect for visible wear or fraying periodically, especially in high‑traffic environments.

Conclusion

The Akasa USB 3.1 Internal Extension Cable (EXUSBI-40) offers a reliable, aesthetically pleasing solution for extending internal USB connectivity within a computer case. Its compact length, robust construction, and straightforward installation make it an essential component for builders seeking both performance and convenience.
