Product description What this card does PCIe expansion card that adds a front/rear USB TypeC data port to a desktop PC. Powered by the ASM1042 chipset and designed for speed data transfer and stable host connectivity. Key benefits — why you need it Add a modern TypeC data port to older desktops quickly using an available PCIe slot (x1, x4, x8 or x16). Reliable 5 Gbps transfers for external SSDs, flash drives, and USB peripherals. Builtin 5 V, 3 A output from the TypeC port supports buspowered devices without requiring host PD or Thunderbolt support. Optional SATA 15pin auxiliary power input lets you supply extra power for current USB devices, preventing underpowered peripherals and improving stability. Important limitations (avoid misuse) The TypeC port does not carry audio, video, or docking signals. It does not support PD (power delivery), DP Alt Mode, or Thunderbolt devices. Use this card for USB data and 5 V device power only. Compatibility and drivers OS compatibility: Windows 7, 8, 10, 11 and Mac OS 10.8.2 and later. Automatic driver support on Windows 10/11, Mac OS, and Linux — no driver install required. Windows 7 requires installation of the appropriate driver. Technical highlights Controller: ASM1042 chipset for stable USB host performance. Data rate: up to 5 Gbps. Port power: supports 5 V, 3 A from the TypeC port. Auxiliary power: accepts SATA 15pin power connector to boost available current for demanding USB devices. PCIe slot compatibility: fits PCIe x1, x4, x8, and x16 slots. Practical use cases 1) Add a TypeC port to an older desktop so you can connect a modern external SSD enclosure and get up to 5 Gbps transfers for fast file backups and media editing. 2) Connect USB TypeC flash drives, card readers, or USB audio interfaces that require standard USB power (5 V) and throughput — while supplying extra current via the SATA 15pin power input if needed. 3) Attach USB hubs or multiple lowtomedium power peripherals where additional auxiliary power stabilizes performance and prevents USB disconnects. What it is not Not a video or docking solution. Do not use for USBC monitors, DP Alt Mode adapters, PD charging of laptops, or Thunderbolt peripherals. Packaging note This description covers the card's functions, chipset, power and slot compatibility, and OS/driver requirements as supplied. Follow driver installation instructions for Windows 7 and connect the SATA 15pin power cable if your attached devices need extra current.
