1. The interface is USB3.0 19PIN TYPE-E 20PIN adapter card - the interface is USB3.0 19PIN TYPE-E 20PIN, the connection is stable. Installed on the PCI bracket to help you easily connect the device to the C-type interface. 2. Uses GEN1 signal, the transmission rate is up to 5Gbps, because the motherboard's 19PIN design is all (i.e., USB3.0 5Gbps\"), so how fast the motherboard's transmission is, how fast the transmission can be 3. Support for systems: which can support USB3.0 can be used, needs motherboard or expansion card with 19PIN socket and chassis with TYPE-E cable 4. Easy to install and install, it's just an extension/port, so no driver installation is required. 5. Please note that the adapter card requires the motherboard to support USB3.0 19PIN before it can be used. A 19PIN interface can extend 2 USB3.0 Product Parameters: Product Name: USB3.0 19PIN to TYPE-C Front TYPE-E Interface Adapter Card Product Interface: USB3.0 19PIN USB3.1 TYPE-E Support for Systems: Support for motherboards or expansion cards with 19PIN sockets and chassis with TYPE-E line USB3.0 systems can be used Function: Convert motherboard's USB3.0 19PIN to TYPE-C Front TYPE-E 20PIN Note: Since 19PIN is GEN1 5Gbps speed, the output is only 5Gbps speed, so the speed cannot be increased.
