PCIe 4x to dual USB 3.1 Gen 2 Type-C card

This expansion card adds two USB 3.1 Gen 2 Type-C ports running at 10 Gbps through a single PCIe 4x slot. It uses the ASM3142 controller and is compatible with Windows and Linux systems. The card fits 4x, 8x or 16x slots and is backward compatible with USB 3.0 and USB 2.0 devices.

Mandatory SATA power and SSD requirement

A 15-pin SATA power connector must be plugged in for the card to operate. The supplier notes that ordinary hard disks cannot saturate the 10 Gbps link; an SSD or compatible drive enclosure is needed to reach the advertised throughput. The SATA power socket is plastic, so the cable should be inserted carefully against the back of the socket.

Plastic SATA socket demands careful insertion

The 15-pin SATA power socket is plastic rather than metal, making the connection relatively tight. Forcing the cable can tilt the socket upward, so align it squarely and press gently against the rear of the socket. This mechanical detail affects day-to-day reliability when installing or reseating the card.

Questions about this item

Will the 15-pin SATA power connector need replacement if it becomes loose?

The supplier notes the plastic SATA socket can tilt if forced; plug the cable firmly against the back of the socket to avoid damage.

What limits sustained transfer speed on this expansion card?

The card runs at USB 3.1 Gen 2 10 Gbps, but ordinary hard disks cannot reach that rate; an SSD is required for full speed.

How much heat or noise does the ASM3142 card produce during all-day use?

The card draws power from the 15-pin SATA connector and has no fan; heat and noise are minimal in typical operation.
