Twoport USB 3.2 Gen1 TypeC PCIe expansion card: adds two USBC ports to your desktop, enabling faster data transfer and flexible peripheral connection. PCI Express compatibility: supports PCIe x1, x4, x8, and x16 slots, allowing flexible installation in a wide range of motherboards. Gen1 performance: each port supports USB 3.2 Gen1 data rates (up to 5 Gbps), providing improved transfer speeds for USBC devices. Operating system compatibility: works with Windows XP, Windows Vista, Windows 7, Windows 8, and Windows 10. Practical use scenarios: Expand USBC connectivity on an older desktop to connect fast external SSDs, cameras, or other USBC peripherals. Build a compact workstation or home office PC that requires easily accessible USBC ports for smartphones, cameras, or USBC hubs. Upgrade a system lacking USBC ports to improve compatibility with modern USBC devices for data transfer and peripheral use.
