USB-C 10Gbps PCIe Card - 2-Port USB 3.2 Gen 2 PCIe Adapter

Our review of this 2-port USB-C PCIe card finds it a practical upgrade for desktop users who need faster external storage access and modern USB-C connectivity. It is best for builders and power users who have an available PCIe 3.0 x4 slot and want 10Gbps USB-C ports without changing their motherboard. The single biggest reason to buy is the card's clear focus on high data throughput for NVMe enclosures and SSDs, delivered via the ASMedia ASM3142 controller and support for USB 3.2 Gen 2 speeds.

Key Features

• Dual 10Gbps USB-C ports: Adds two SuperSpeed 10Gbps Type-C ports so external NVMe drives and high-performance SSDs can reach their potential.
• ASMedia ASM3142 chipset: Uses a dedicated host controller over PCIe 3.0 x4 lanes to maintain high sustained transfer rates for large file work.
• UASP support: USB Attached SCSI Protocol reduces CPU overhead and improves throughput and latency with compatible storage devices.
• Up to 5V 3A per port: Provides up to 15W per port for charging and powering small USB-C devices without an external adapter when using the optional power connector.
• Full and low-profile fit: Ships with a low-profile bracket so it installs in both standard desktops and small form-factor cases.
• Cross-platform compatibility: Works with Windows, macOS and Linux with auto-install drivers for most modern systems.

Who It's For

This card is ideal for desktop users who need extra high-speed USB-C ports for external NVMe enclosures, backup drives, or fast data transfers from professional cameras and media storage. Builders who prefer an internal expansion card over a front-panel hub will appreciate the clean, permanent solution.

It is not for users who need USB video output, Power Delivery negotiation beyond basic 5V charging, or Thunderbolt speeds; the card explicitly supports data only and does not provide DisplayPort Alt Mode or full PD/Thunderbolt compatibility.

Pros & Cons

Pros

• Simple installation in a PCIe 3.0 x4 slot with a low-profile bracket included.
• Supports true USB 3.2 Gen 2/USB 3.1 Gen 2 10Gbps speeds for high-performance drives.
• UASP support improves sustained transfer rates with compatible storage devices.
• Provides up to 5V 3A per USB-C port for device charging when powered.

Cons

• Data-only limitation: no DisplayPort Alt Mode, advanced USB Power Delivery, or Thunderbolt support; not a video or full PD solution.
• Some users report mixed driver experience on certain Windows 10/11 systems, so driver behavior can vary by motherboard and OS.

Our Verdict

The card is a solid, cost-effective way to add 10Gbps USB-C ports to a desktop for high-performance storage and peripherals. It delivers good value for users who need raw data throughput and a clean internal install, though buyers who need video output, Thunderbolt, or advanced PD should look elsewhere.

Frequently Asked Questions

Does this card provide video over USB-C?
Answer. No, it supports data only and does not provide DisplayPort Alt Mode for video output.

Will it work in older PCIe slots?
Answer. Yes, it is backward compatible with PCIe 2.0 but will run at reduced performance if not installed in a PCIe 3.0 x4 slot.

Does it require extra power for high-power devices?
Answer. The ports supply up to 5V 3A each, and an optional SATA power connector is available for devices that need additional power.
