PCIE USB Adapter: PciE X1 To Dual Port PCIE X4 Convert Card, Working For Motherboard PCIE Slot USB 3.0 Interface Extender: Quality And Super Speed PCI Express X1 Bus Type: PCIE 1x Extended Expansion Card 90 Degree Right Angle, Save Space Design Gold Plated Contacts For Better Connectivity Key benefits and features Expands PCIe capability from a single PCIe X1 slot: converts a PCIe X1 interface into dual PCIe X4 expansion ports to support additional PCIe devices. speed USB 3.0 interface: enables fast data transfer for USB devices connected through the extender, with quality construction for reliable performance. Spacesaving 90degree rightangle design: compact form factor helps fit into tight or compact PC builds while maintaining access to expansion slots. Reliable connectivity: gold plated contacts improve signal integrity and longterm connection reliability. Compatibility and usage: designed for motherboards with PCIe slots that support PCIe X1 as the bus type; suitable for systems requiring extra PCIe X4 lanes from a single X1 slot. Specifications and design notes Bus type: PCI Express X1 (PCIE 1x) Expansion: dual port PCIE X4 conversion card Orientation: 90 degree rightangle design to save space Interface: USB 3.0 interface extender embedded within the PCIe expansion functionality Contact material: gold plated contacts for better connectivity Practical use scenarios Small form factor builds: install in a motherboard PCIe X1 slot to gain two PCIe X4 expansion paths without occupying additional space, enabling use of more PCIe cards or devices. speed USB 3.0 connectivity: extend USB 3.0 performance to external storage devices or speed USB peripherals by leveraging the dual X4 expansion from a single X1 slot. Testing and workstation setups: convenient spacesaving expansion in test benches or compact workstations where multiple PCIe devices are needed but available slots are limited.
