Green PCB PCIe x4 card with silver bracket and single USB-C port

SMUGDESK

SMUGDESK PCIe 4X to USB3.2 Gen2x2 20Gbps Type-C Expansion Card

SKU CH-8JB1-F2EW2

Adds a 20 Gbps USB 3.2 Type-C port via PCIe x4 using an ASM3242 controller for fast external storage

  • 20 Gbps peak throughput via USB 3.2 Gen 2×2 specification
  • ASM3242 controller chip delivers stable high-speed data transmission
  • Single USB-C port connects SSDs, docks and fast peripherals directly
  • Standard bracket fits PCIe x4, x8 and x16 slots in desktop cases
  • Windows and Linux driver support enables plug-and-play operation

Ultra-Fast 20Gbps Type-C Upgrade

This PCIe expansion card adds a single USB3.2 Gen2x2 Type-C port to a desktop computer, delivering up to 20Gbps bandwidth for rapid data transfers. It targets users who need to connect high-speed external SSDs or docking stations directly to the motherboard via a standard PCIe x4 slot.

ASM3242 Chip Stability

The card uses an ASM3242 master control chip to maintain consistent transmission performance during sustained workloads. It draws power solely from the PCIe slot without requiring auxiliary connectors, keeping installation simple and thermal load minimal inside the chassis.

Broad OS Driver Support

Bundled drivers enable plug-and-play operation on mainstream Windows and Linux distributions, removing the need for manual configuration. The standard PCI bracket ensures a secure fit in regular desktop cases, while PCIe x4/x8/x16 slot compatibility provides flexible motherboard placement options.

Questions about this item

How do I install the card and which bracket screw do people forget?

Insert the card into any PCIe x4, x8 or x16 slot, secure the standard bracket with the case screw, then install the ASM3242 driver on Windows or Linux.

What part will need replacement first under heavy use?

The ASM3242 controller chip handles sustained 20Gbps loads; if it fails the whole card must be swapped as no user-serviceable parts exist.

What throughput limit appears first during long transfers?

The PCIe x4 link caps sustained throughput at 20Gbps per the USB3.2 Gen2x2 spec, so extended copies cannot exceed that ceiling.
