Four independent USB-C controllers

This PCIe 3.0 add-in card adds four USB 3.2 Gen 2 Type-C ports to a desktop or server. Each port is driven by its own controller so bandwidth is not shared between devices. The card suits users who need multiple simultaneous 10 Gbps connections for external storage or high-performance peripherals. It supports Windows, Linux and macOS without extra drivers.

Auxiliary SATA power delivers 15W per port

A SATA power connector supplies up to 15W to each port so bus-powered drives and accessories run without external adapters. The plug-in form factor draws power only from the slot and the auxiliary connector keeping cable routing simple. Independent controllers help maintain consistent throughput under load while the low-profile bracket fits compact chassis.

Red PCB with low-profile bracket included

The red circuit board makes the card easy to identify inside a busy build. A low-profile bracket is supplied for small-form-factor cases while the standard bracket works in full-size towers. Four Type-C ports face the rear panel giving clean access for cables and docks. No internal headers or extra cabling are required.

Questions about this item

How do I install the card and which bracket do I use for a low-profile case?

Install the card into a PCIe 3.0 x4 or larger slot, attach the included low-profile bracket, then connect the auxiliary SATA power cable to supply 15W per port before booting the OS.

What maintenance or replacement will the card need over time?

No scheduled maintenance is required; only the auxiliary SATA power connection and the four USB Type-C ports may need attention if cables wear or the power supply cannot sustain 15W per port.

What limit appears first when all four ports run sustained 10Gbps transfers?

The PCIe 3.0 host link and the shared SATA power feed become the bottlenecks before any single 10Gbps controller reaches its own ceiling.
