InLine USB 3.0 Internal Adapter Cable 2x USB Type-A Female / Mainboard Header

The InLine USB 3.0 Adapter Cable (33445I) provides two USB 3.0 Type-A female ports wired to a 19-pin motherboard connector, enabling direct connection of two external USB 3.0 devices to a compatible mainboard header. The compact 0.15 m cable in black is designed to expand internal USB connectivity where front-panel or chassis ports are unavailable or additional ports are required.

Advantages

This adapter cable offers a straightforward way to add two USB 3.0 Type-A female ports to a motherboard header without requiring internal modification of devices. Its short length reduces cable clutter inside the case, and the standard 19-pin connector ensures compatibility with motherboards that provide an internal USB 3.0 header.

Suitable for

• Connecting two external USB 3.0 devices to a motherboard header
• Expanding internal USB ports for front-panel or accessory adapters
• Systems with limited external USB ports or when routing cables inside the case
