PCIe 4x USB 3.1 Gen 2 Card

This PCI Express 4x expansion card adds two USB 3.1 Gen 2 Type-C ports to a desktop system. It fits PCIe 4x, 8x or 16x slots and is compatible with Windows 7, 8, 10, Linux and macOS 10.14. The ASMedia ASM3142 chipset provides up to 10 Gbps bandwidth per port for fast data transfer with external storage or peripherals.

Thermals and Power in Normal Use

The card draws power from the PCIe slot and includes a SATA 15-pin power connector for additional current when needed. Built-in over-current and short-circuit protection safeguards each port during everyday operation. Bus-powered mode handles most peripherals without external power, keeping heat output low in typical desktop workloads.

Behaviour Under Sustained Load

Each Type-C port can deliver 5 V at up to 2 A continuously, supporting device charging alongside data transfers. The PCIe 2.0 x4 host interface maintains full-duplex 10 Gbps throughput during prolonged file copies. Backward compatibility with USB 3.0 and 2.0 ensures stable connectivity even when older devices share the bus.

Questions about this item

How do I install the card and which slot mistake should I avoid?

Insert the PCIe 4x connector into a PCIe x4, x8 or x16 slot — it will not work in a PCIe x1 slot — then secure the low-profile bracket if your case needs it.

What maintenance will the card need over time?

No scheduled maintenance is required; the on-board over-current and short-circuit protection on each Type-C port handles fault conditions automatically.

What limit appears first during sustained 10 Gbps transfers?

The PCIe 2.0 x4 bus caps sustained throughput at roughly 16 Gbps total, so both ports cannot run at 10 Gbps simultaneously.
