Two independent 10Gbps Type-C ports

The SMUGDESK 00999/OO999/SC50T22878 PCIe expansion card adds dual USB3.1 Gen2 Type-C connectors to a desktop PC. Each port is driven by an ASMedia ASM1142 controller and delivers 10Gbps without sharing bandwidth. It suits video editors and workstation users who need fast external storage or docking stations. No extra SATA power cable is required.

Sustained full-speed operation without bandwidth

Dual independent ASM1142 controllers keep both ports at 10Gbps during long transfers such as large backup jobs or continuous video ingest. Overcurrent and overvoltage protection on each port maintains stability under heavy load. The card auto-adapts to PCIe Gen3 x1 or Gen2 x2 slots and works in x4, x8 or x16 motherboard slots.

x4 PCIe interface with low-profile bracket included

The card installs in any PCIe x4, x8 or x16 slot and includes both standard and low-profile brackets for ATX desktops and 1U/2U slim chassis. Plug-and-play drivers cover Windows 11, 10, 8.1, 7 and Linux, with backward compatibility to USB3.0, 2.0 and 1.1 devices. It is not for systems lacking a free PCIe slot.

Questions about this item

How much power does the ASMedia ASM1142 controller draw when both Type-C ports run at 10Gbps all day?

The card draws all required power from the PCIe slot itself; no extra SATA power cable is needed even under continuous 10Gbps load.

Which motherboard slot and bracket size do I need to install this expansion card?

It fits any PCIe x4, x8 or x16 slot and ships with both a full-height and a low-profile bracket for ATX or 1U/2U chassis.

Will my existing USB 3.0 and USB 2.0 peripherals work at full speed when plugged into the new Type-C ports?

Yes, the ports are backward compatible with USB 3.0, 2.0 and 1.1 devices, so older drives and accessories operate at their native speeds.
