InLine USB 3.0 Premium adapterkabel 2x USB-A stekker / mainboard-header, 0,40 m

The InLine USB 3.0 Premium Adapter Cable (33447I) is a 0.4 m cable with two USB A male connectors that converts to a 19-pin motherboard internal USB 3.0 header. It is designed to connect internal USB 3.0 devices to a PC mainboard and supports USB 3.2 Gen 1 (also marketed as USB 3.1 Gen 1) with up to 5 Gbit/s data transfer speed. The cable comes in a black finish suitable for use inside desktop systems.

Advantages

The adapter cable provides a direct internal connection from two external-style USB A male plugs to a 19-pin mainboard header, enabling the use of internal USB 3.0 devices without additional converters. With USB 3.2 Gen 1 support and a short 0.4 m length, it reduces signal loss and clutter inside the case while delivering up to 5 Gbit/s bandwidth. The black colour integrates discreetly into most system interiors.
