SKU CH-W64Q-M55XW

Adds two USB-C ports with 10 Gbps transfer speed via a PCIe 3.0 x4 slot and includes both full-profile and low-profile brackets

  • Adds two USB-C ports for fast external storage
  • Delivers up to 10 Gbps transfer speed with USB 3.2
  • ASMedia ASM3142 controller ensures stable performance
  • Optional SATA 15-pin power supplies 900 mA per port
  • Includes full-profile and low-profile brackets for any case

Dual USB-C PCIe 3.0 x4 Card

This add-on card adds two USB-C ports to a desktop computer through a PCIe 3.0 x4 slot. It uses the ASMedia ASM3142 chipset to deliver USB 3.2 10Gbps speeds. The card fits x4, x8 or x16 slots but will not work in an x1 slot. It is built for users who need fast external storage or device connectivity.

Thermals noise and power draw

The card draws auxiliary power from a SATA 15-pin connector to supply up to 900mA per port at 5V. No active cooling is present so the board runs silently. Power consumption stays low because the ASM3142 controller is efficient and the card has no onboard fan or heatsink.

Build fit and flexibility

Both full-profile and low-profile brackets are included so the card fits standard and slim chassis. Backward compatibility lets you use existing USB 3.0 5Gbps and USB 2.0 480Mbps devices without adapters. The SATA power lead must reach the card from the power supply. Builders needing more than two ports or an x1-only slot should choose a different card.

Questions about this item

How do I install the Vszerda dual USB-C PCIe 3.0 x4 card and which bracket should I use?

Insert the card into any PCIe x4, x8 or x16 slot — it will not work in an x1 slot. Choose the full-profile bracket for standard cases or the low-profile bracket for slim chassis; secure the chosen bracket before seating the card.

What maintenance will the ASM3142 card need and when should I check the SATA power connection?

No scheduled maintenance is required. Periodically verify that the SATA 15-pin power connector remains firmly seated so each USB-C port can continue delivering up to 900 mA.

What is the first limit I will hit during sustained 10 Gbps transfers on both USB-C ports?

The PCIe 3.0 x4 host link and the ASM3142 controller share a 10 Gbps ceiling, so simultaneous heavy traffic on both ports will saturate that bandwidth before any other bottleneck appears.
