The adapter is a converter to convert the available USB 3.0 header of a motherboard into a USB 3.1 header.
Thus the USB 3.1 port of a housing can also be supplied with USB 3.1 without a suitable mainboard.
The compact adapter can be inserted directly and requires no additional attachments.
Converter plug-in for the mainboard
Fits into any USB 3.0 header
Bundling in USB 3.1 with up to 5 GBit / s
Convenient accessory for case with USB 3.1 connector
Even the most up-to-date motherboards with AMD AM4 or Intel 2066 sockets are not always equipped with a USB 3.1 header.
The adapter is the perfect solution to use the USB 3.1 connectors with Type-C Socket Key-B or Type-A.
The small converter is plugged into a USB 3.0 header that provides two USB 3.0 lanes.
The converter thus provides a full-fledged USB 3.1 port.
