Built on the proven ASM3142 + VL820-Q8 chipset combination, this card delivers robust performance, excellent compatibility, and future-proof connectivity in one package.

Key Features

Chipset / Architecture
Utilises ASMedia ASM3142: A PCIe-to-USB3.1 Gen2 host controller supporting up to 10 Gbps per port and compliant with the xHCI 1.1 specification.
Uses VIA Labs VL820-Q8: A multi-port USB 3.1 Gen2 hub supporting 10 Gbps and designed for multi-downstream port layouts

Interface
Plugs into your motherboard’s PCIe slot (typically PCIe x4 or higher).
Backward compatible with PCIe 2.0/3.0 depending on your motherboard.
Supports USB 3.1 Gen2 (“SuperSpeed+”) up to 10 Gbps.

Ports
External ports: e.g., 4 × USB-A (Type-A) + 4 × USB-C (Type-C).
All ports capable of USB3.1 Gen2 speeds (10 Gbps) when properly supported.
Backward compatible with USB 3.0, 2.0, 1.x devices.

Performance / Compatibility
Each port supports high-speed transfers up to 10 Gbps (when the host slot and connected device support it).
Compatible with modern operating systems: Windows (Win7/8/10/11), Linux kernels (various).
Ideal for connecting fast external SSDs, USB-C docks, multi-port hubs, and more.

Power & Protection
Ports include over-current protection and independent port power control.
Ensure your motherboard slot provides sufficient current for multiple high-power devices.

Form-Factor & Installation
Full-height bracket included. (It does not support low profile bracket)
Requires free PCIe slot (preferably x4 or x16 for full bandwidth)
Plug and play in most cases; driver installation may be required for older Operating Systems.

Benefits & Use Cases

- Upgrade older PCs that lack USB-C or high-speed USB ports: you now get 10 Gbps external connectivity.
- Content creators, power users transferring large video/audio files or backing up large external SSDs will appreciate the higher throughput.
- Workstations/servers needing multiple external USB ports for storage devices, backup drives, docking setups.
- Gaming/VR rigs – connect multiple VR devices, high-speed capture devices, etc., without relying solely on onboard ports.

Specifications

Important Considerations & Compatibility Tips

• Slot bandwidth matters: To realise full 10 Gbps speeds on all ports, ensure the PCIe slot is x4 (or more) and your motherboard supports sufficient lanes/bandwidth. Some users report limited performance when the card is placed in a slot with fewer lanes.
  
• Device support: The connected USB device must also support USB 3.1 Gen2 (10 Gbps) to get full speed; if it’s USB3.0 (5 Gbps) or USB2 (480 Mbps), you’ll be limited accordingly.
  
• Motherboard compatibility: Some older motherboards may need BIOS updates; some cards may not show full speed if chipset drivers/firmware are outdated.
  
• Cables matter: For USB-C devices expecting 10 Gbps, ensure you use a USB-C cable rated for USB 3.1 Gen2, as cheaper cables may be limited to 5 Gbps.
  
• Power supply: If you plan to attach many high-current USB devices (SSD enclosures, etc.), make sure your system’s power and slot can handle the load.
  
• Heat & cooling: While these cards aren’t typically extremely hot, multi-port high-speed cards can heat up under heavy load; allow for airflow.
  
• Driver & OS support: While Windows 10/11 and most Linux kernels support the ASM3142 and VL820 series, older OSes (Windows 7/8) might need manual driver installation.
  
• Shared bandwidth: If all ports are used simultaneously at high speed, total throughput is shared over the PCIe interface — performance may vary.
