SMUGDESK

SMUGDESK PCIe to 4-Port USB 3.0 Expansion Card

SKU CH-M6SX-B9DPS

Adds four USB 3.0 ports through a PCIe slot with 5Gbps speed and backward compatibility

  • Adds four USB 3.0 ports through a single PCIe X1 slot
  • Delivers up to 5Gbps throughput for faster file transfers
  • Works in X1, X4, X8 or X16 slots on Intel and AMD boards
  • Runs USB 2.0 and 1.1 devices without extra adapters
  • Installs on Windows and Linux with plug-and-play simplicity

Four-Port USB 3.0 Expansion

This PCIe add-in card adds four independent USB 3.0 ports to a desktop computer through a single PCIe x1 slot. It targets PC owners who have exhausted their motherboard headers and need more connections for flash drives, external storage, webcams or similar peripherals. The board works with both Intel and AMD platforms running Windows or Linux.

Fits Multiple Slot Sizes

The card is compatible with PCIe x1, x4, x8 and x16 slots, so it can be installed in almost any free expansion slot on a mainstream desktop motherboard. Each port maintains its own 5 Gbps channel, allowing several high-speed devices to operate simultaneously without sharing bandwidth. Legacy USB 2.0 and 1.1 devices are also supported for backward compatibility.

Limited to 5 Gbps Per Port

The USB 3.0 interface caps each port at 5 Gbps, which is slower than newer USB 3.1 or 3.2 standards that reach 10 Gbps or higher. The card draws power solely from the PCIe slot, so it cannot supply the higher current needed for bus-powered 2.5-inch drives without an auxiliary power connector that this model lacks. Builders needing faster transfers or more power per port should consider a different controller.
