ST-JY 20Gbps USB-C PCIe Card – The Ultimate Speed Upgrade for Desktop Why settle for slow 5Gbps or 10Gbps ports? Add 20Gbps USB-C ports to your PC with the most reliable ASM3242 solution. [Key Features] ✅ True 20Gbps (USB 3.2 Gen2x2) – Transfer 100GB in under 50 seconds ✅ ASM3242 controller – Low latency, high stability ✅ No external power – Clean installation, save PSU ports ✅ PCIe 3.0 x4 interface – Full bandwidth, no bottleneck ✅ Includes full-height & low-profile brackets [Technical Specs] - Chipset: ASMedia ASM3242 - Host interface: PCI Express x4 (PCIe 3.0) - Output: 1x USB-C (20Gbps, 5V/3A power output) - Power: Bus-powered from PCIe slot (max 10W) - OS support: Windows 10/11 (native driver), Linux (kernel 5.5+) [Compatibility Check] - Your motherboard must have an unused PCIe x4, x8, or x16 slot. - Does NOT work in PCIe x1 slot. - For high-power devices (external HDD/SSD that draw >2A), use a powered USB hub. [Package Included] 1x PCIe USB-C Card, 1x Low-profile bracket

• Ultra-Fast 20Gbps Speed – True USB 3.2 Gen2x2 Equipped with ASM3242 controller, this PCIe to USB-C card delivers up to 20Gbps bandwidth — double the speed of standard 10Gbps USB 3.2 Gen2. Transfer 4K videos, large backups, or VR data in seconds. Backward compatible with 10Gbps/5Gbps devices.
• No External Power Required – Plug & Play Unlike many high-speed USB cards, this PCIe x4 adapter draws all power from the PCIe slot. No SATA power or Molex cable needed. Perfect for desktops with limited PSU connectors or clean cable management. (Note: For high-power devices >15W, use self-powered hubs.)
• ASM3242 Native Chipset – Broad Compatibility Built with ASMedia ASM3242 (the most mature 20G host controller). Supports Windows 10/11, Linux Kernel 5.5+.
• PCIe x4 Interface – No Lane Bottleneck Uses PCIe 3.0 x4 (or x8/x16 slot) for full 20Gbps throughput. Includes a low-profile bracket for small form factor (SFF) cases. Backward compatible with PCIe x8/x16 slots. LED indicator for link status.
• What You Get ----1x PCIe to USB-C 20G Card (ASM3242), 1x Low-Profile Bracket. 12-month warranty & 24/7 tech support. Note: Requires PCIe x4 or larger slot. Not for PCIe x1 slots.
