SMUGDESK PCIe USB 3.2 Gen 1 Expansion Card 4 Ports (2 USB-C + 2 USB-A)

PCIe x1 USB 3.2 Gen 1 Expansion Card

This expansion card occupies a single PCIe x1 slot and adds four external ports: two USB-C and two USB-A. It targets desktop users whose motherboard rear panel lacks enough modern connections for current peripherals. The mixed port layout lets you attach new Type-C drives and legacy Type-A devices simultaneously. No external power cable is required because the card draws current directly from the slot.

Sustained 5 Gbps throughput for large transfers

The controller follows the USB 3.2 Gen 1 specification with a 5 Gbps signalling rate, maintaining that bandwidth during extended file copies rather than only in short bursts. Backward compatibility with USB 2.0 and 1.1 ensures older devices still function at their native speeds. Stable bus power delivery keeps portable SSDs and docking stations running without voltage drops during long write sessions. Windows recognises the card automatically, so no driver management interrupts the workload.

Full-height metal bracket for secure mounting

A standard full-height metal bracket screws firmly to the chassis rear panel, preventing the card from shifting when cables are plugged or unplugged. The bracket also shields the circuitry from dust and electromagnetic interference inside the case. Installation is purely mechanical: insert the card, secure the screw, and the ports are immediately active. This makes the adapter a practical, low-maintenance upgrade for DIY assemblers, office desktops and data-storage workstations.
