Two 10Gbps Type-C ports for desktop expansion

The SMUGDESK U3142CX1 adds two independent USB 3.1 Gen2 Type-C connectors to any desktop through a single PCIe x1 slot. Each port delivers up to 10Gbps bandwidth for external SSDs, portable drives and high-speed peripherals. The ASMedia ASM3142 controller ensures stable transmission and backward compatibility with USB 3.0, 2.0 and 1.1 devices. It suits owners of older systems who need modern Type-C connectivity without replacing the motherboard.

Passive cooling and minimal power draw

The card operates without a fan, relying on its compact PCB and the chassis airflow for silent thermal management. Power is drawn solely from the PCIe x1 interface, requiring no extra cables or external supply. Typical load from connected USB devices stays within the slot specification, so the host system sees no measurable increase in idle or peak consumption. The low-profile design fits tight SFF cases where airflow is already limited.

Full-height and low-profile brackets included

Two mounting brackets ship in the box, letting the same card serve standard ATX towers and slim small-form-factor desktops. Swapping brackets takes seconds and needs only a screwdriver, so the adapter moves between chassis types without extra cost. Drivers are built into current Windows and Linux kernels, giving true plug-and-play operation with no separate software install. The package contains only the card, brackets and a quick-install guide.

Questions about this item

How do I install this PCIe x1 card and which bracket do I use for a slim case?

Insert the card into any PCIe x1, x4, x8 or x16 slot; use the low-profile bracket for slim SFF chassis and the full-height bracket for standard ATX cases.

What maintenance or replacement will the ASM3142 controller need over time?

The ASM3142 controller has no user-serviceable parts; if a port fails the whole card must be replaced.

What limit appears first when both Type-C ports run at 10Gbps continuously?

The single PCIe x1 lane caps total throughput, so sustained dual-port traffic will hit that bandwidth ceiling before the controller does.
