Internal Adapter Cable Akasa AK-CBUB53-40BK USB 3.1 Gen 1 Dual USB 2.0 Type-A

The Akasa internal adapter cable provides two front-access USB Type-A ports connected via a USB 3.1 Gen 1 internal header. Designed for installation in a desktop PC case, the adapter includes a full-profile PCI bracket in black finish to mount the ports securely and maintain a clean external appearance. The cable routes the motherboard’s internal USB header to two standard USB 2.0 Type-A sockets, enabling connection of peripherals from the front or rear expansion slot area without altering the case exterior.

Advantages

This adapter supports internal USB 3.1 Gen 1 headers while exposing dual USB 2.0 Type-A connectors, offering compatibility with a wide range of peripherals. The included full-profile PCI bracket ensures stable mounting and a uniform look with standard desktop chassis. Its compact black design reduces visual clutter and preserves case airflow. The passive cable preserves signal integrity for USB 2.0 devices and requires no additional drivers or power beyond the motherboard connection.

Suitable for

• Connecting keyboards, mice and low-bandwidth peripherals to an available internal USB header
• Adding two external USB Type-A ports using an empty PCI slot opening
• Organizing cable routing for front or rear access to USB ports in a desktop PC

Key specifications

How to use

Power off the PC and unplug it from the mains before installation. Remove the case side panel and locate an empty full-height PCI expansion slot. Secure the bracket in the slot, then route the cable to an available internal USB 3.1 Gen 1 header on the motherboard and connect it with the correct orientation. Reassemble the case and power on the system. The connected USB Type-A ports will be available for use immediately with USB 2.0 devices; no driver installation is required.

Recommendations

Use this adapter for peripherals that do not require high USB 3.x transfer rates; reserve USB 3.1 Gen 1 header bandwidth for high-speed devices when necessary. Ensure the internal header on your motherboard matches the connector type and pin count before installation, and avoid forcing the connector to prevent bent pins.
