USB 3.2 Gen2×2 20Gbps PCIe x4 to Type-C Expansion Card
USB 3.2 Gen2×2 20Gbps PCIe 3.0 x4 to Type-C Expansion Card
Upgrade your desktop PC with blazing-fast USB 3.2 Gen2×2 connectivity. This PCIe expansion card installs into any available PCI-E x4, x8, or x16 slot and adds a single high-speed USB Type-C port capable of up to 20Gbps data transfer — ideal for the latest external SSDs, NVMe enclosures, docking stations, and other USB-C peripherals that demand maximum throughput.
Powered by the proven ASMedia ASM3242 controller chip, this card delivers full USB 3.2 Gen2×2 bandwidth. A SATA power connector provides stable supplemental power to connected devices, and a low-profile bracket is included for compact or small-form-factor cases.
⚠ Important Notes:
- Your host PC and connected device must both support the USB 3.2 Gen2×2 protocol to achieve 20Gbps speeds.
- Thunderbolt 2, 3, and 4 ports are backward compatible with USB 3.1 Gen2 (10Gbps) only — they do not support the full 20Gbps Gen2×2 mode.
- Compatible operating systems: Windows 10 and Windows 11. Windows 7 and Windows 8 are not supported.
- Made in Mainland China.

Frequently Asked Questions
Q: Does this USB 3.2 Gen2×2 PCIe card require a separate power connection?
A: Yes. The card includes a SATA power connector that must be connected to your PC's power supply for stable operation, especially when powering demanding USB-C devices like external NVMe drives.
Q: Which PCIe slot sizes is this Type-C expansion card compatible with?
A: The card uses a PCIe x4 interface but is compatible with x4, x8, and x16 PCIe slots on desktop motherboards. It is not compatible with PCIe x1 slots due to its x4 lane requirement for full 20Gbps bandwidth.
Q: Will this card work with my Thunderbolt port or device?
A: Thunderbolt 2, 3, and 4 are backward compatible with USB 3.1 Gen2 (10Gbps), but they do not support the USB 3.2 Gen2×2 (20Gbps) protocol. To achieve 20Gbps, both the host card and the connected device must natively support USB 3.2 Gen2×2.
Q: Is this PCIe USB-C card compatible with Windows 11?
A: Yes. This card is fully compatible with Windows 10 and Windows 11. Windows 7 and Windows 8 are not supported. No additional driver installation is required for most Windows 10/11 systems.
