Connector1: USB 3.0 20Pin Socket.
Connector2: USB 3.1 20pin Front Panel Header. ^^ The adapter is a converter to convert the available PCI-E 1x 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. ^^ The adapter is the perfect solution to use the USB 3.1 connectors with Type-C or Type-A.
