PCIe Gen3 x4 USB-C 3.2 Gen2x2 20Gbps Expansion Card with 20W QC Fast Charging, SATA 15Pin Powered, ASMedia ASM3242 Controller, Full & Low Profile Brackets for Desktop PC

This PCIe Gen3 x4 expansion card adopts premium ASMedia ASM3242 dedicated controller chip, supporting USB 3.2 Gen2x2 dual-lane transmission up to 20Gbps, twice faster than regular 10Gbps USB 3.2 Gen1 ports. It drastically accelerates large file transfer, 4K/8K video editing and NVMe external SSD data backup for creative workstations and gaming desktops.

Equipped with one external USB-C port integrating 20W QC quick charging function, it can rapidly power and charge smartphones, tablets, wireless earbuds and other Type-C gadgets without separate wall chargers. The built-in 15Pin SATA power connector draws steady power directly from PC power supply, eliminating insufficient power disconnection issues when running power-hungry storage devices continuously.

Comes with two interchangeable metal brackets: full-height standard bracket for full-size ATX/MATX towers and low-profile flat bracket for compact mini ITX slim hosts. Fully backward compatible with USB 3.2 Gen1, USB 3.0 and USB 2.0 devices, and supports UASP acceleration protocol to boost storage performance.

Plug-and-play design works seamlessly with Windows 11/10/8, Linux and macOS systems without complex driver installation. Built-in aluminum heatsink efficiently dissipates heat during long-hour high-speed operation, maintaining stable performance for PC DIY upgrades, video production rigs and office desktop expansion.

Note: This card supports data transfer and 20W QC charging only, not compatible with DisplayPort Alt Mode video output.
