InLine USB 3.0 Extension Internal Header Plug/Socket 33448I 0.35m

The InLine USB 3.0 Extension Internal Header Male/Female 0.35m is a short internal cable designed to extend or relocate a USB 3.0 header connection inside a PC chassis. With a male connector on one end and a female connector on the other, the cable provides a direct continuation of an existing motherboard internal USB 3.0 header to a more convenient position for device connection or case front-panel modules. The 0.35 m length balances reach and cable management inside compact and mid-tower systems while preserving the SuperSpeed USB 3.0 signal integrity for connected peripherals.

Advantages

The extension cable supports high-speed USB 3.0 data transfer and maintains the required pinout for internal header connections, enabling reliable performance for internal hubs, front-panel ports, and motherboard expansions. Its compact length reduces clutter and improves airflow compared with longer internal cables, and the male/female header design simplifies installation without the need for adapters. The cable construction is intended for in-case use, with connectors shaped to match standard motherboard header layouts.

Suitable for

• Extending motherboard internal USB 3.0 headers to front-panel ports or internal hubs
• Relocating a USB 3.0 header to a more accessible position inside the PC case
• Connecting internal USB devices such as card readers, controllers, or expansion modules
• Improving cable routing and airflow in compact or mid-tower systems

Key specifications

• Cable type: Internal USB 3.0 header extension (male to female)
• Connector configuration: 20-pin internal header male to female
• Length: 0.35 m
• Compatibility: Standard internal USB 3.0 motherboard headers and compatible front-panel modules
• Data rate: Supports USB 3.0 SuperSpeed signaling

How to use

Power down the PC and disconnect mains power before working inside the case. Identify the motherboard's internal USB 3.0 header and align the male connector with the header pins, ensuring proper orientation. Plug the female end into the internal cable or module you wish to extend or relocate. Confirm secure seating of both connectors and route the cable to avoid interference with fans or moving parts. After reassembling the case, power on the system and verify that connected devices are recognized by the operating system.

Recommendations

Use this cable exclusively for internal connections within a powered-off system. Avoid excessive bending or sharp kinks near the connectors and keep the cable clear of fan blades and heat sources. For optimal performance, keep the total internal USB cable path as short as practical and ensure secure connector seating to prevent intermittent contacts.
