SMUGDESK 4-Port PCIe 2.0 to USB 3.0 Expansion Card

SKU CH-4S3G-R0DQR

Adds four USB 3.0 ports via a PCIe 2.0 x1 slot with hot-swap support for drives and peripherals

  • Adds four USB 3.0 ports for extra peripherals
  • PCIe 2.0 interface delivers 5 Gbps transfer speeds
  • Hot-swap support lets you swap devices without shutdown
  • Fits x1, x4, x8 or x16 motherboard slots
  • Works with Windows and Linux, no drivers needed

Four-Port USB 3.0 Expansion

This SMUGDESK card adds four USB 3.0 Type-A ports to a desktop computer through a single PCIe 2.0 x1 slot. It targets builders who need more high-speed connections for external drives, hubs or mining risers without replacing the motherboard. The plug-and-play design works with Windows and Linux systems.

Sustained 5 Gbps Throughput

The onboard controller maintains the full USB 3.0 5 Gbps rate during extended transfers rather than throttling after a short burst. Hot-swap support lets users attach or remove storage devices while the host stays powered, avoiding downtime on long copy jobs or mining operations.

PCIe x1 Flexible Mounting

The x1 edge connector fits x1, x4, x8 or x16 motherboard slots, giving installers placement freedom inside tight chassis. Four rear-facing ports keep cables accessible at the back panel, and the card requires no auxiliary power cable for operation.
