Note: 

To satisfy USB3.1 10Gb/s Super Speed+ highest performance,  SE-U3A1142-U2 adopts the PCIe Gen 2 , x 2 (10Gb/s) interface connector design. 

User has to plug USB3.1 add-on card into PCIe x16 (or x4 above) slot on the mainboard, suc h as graphics add-on card adopting. 

Due to expansion slot mechanical limitation, this card can Not be plugged into PCIe x1 slot.  If user does not have available PCIe x16 on the mainboard, 

please pick SE-U3A1142-U2 (USB3.1 PCIe add-on  card with 2-port USB Type-C Receptacle) that adopts PCIe Gen 3 x1 (8Gb/s) interface connector.
