Green PCIe x1 card with four USB ports: three blue Type-A and one red Type-C

SMUGDESK

SMUGDESK PCIe to USB 3.0 & USB-C 4-Port Adapter D720201

SKU CH-PJMY-8K0C1

Adds four USB 3.0 and USB-C ports at 5Gbps via a PCIe x1 slot, powered entirely by the motherboard

  • Add four USB 3.0 and USB-C ports at 5Gbps for faster peripheral transfers
  • D720201 controller chip keeps connections stable during long file moves and heavy workloads
  • Draws all power from the PCIe slot — no SATA cable or extra connector needed
  • Fits any PCIe x1, x4, x8 or x16 slot on Intel or AMD desktop motherboards
  • Works with USB 2.0 and 1.1 devices on Windows and Linux without extra drivers

Expansion card for desktop USB port shortage

The SMUGDESK PCIe adapter adds four ports to a desktop computer using a single PCI Express lane. Two USB-A and two USB-C connectors deliver up to 5 Gbps bandwidth for flash drives, external disks and everyday peripherals. The D720201 controller chip is designed for steady long-term operation under typical office or home workloads.

Check motherboard slot and power budget

Verify that an open PCIe x1, x4, x8 or x16 slot is available on your Intel or AMD desktop motherboard. The card draws all power from the slot itself and has no SATA power connector, so the slot must supply enough current for every attached device. Operating system support includes Windows and Linux with backward compatibility for USB 2.0 and 1.1 devices.

Sustained transfer with bus-powered design

During prolonged file copies the card relies solely on motherboard slot power, so total device draw stays within the slot’s current limit. The D720201 controller maintains stable signalling at 5 Gbps across all four ports without an external power feed. Performance scales with the host chipset and connected drive speeds rather than a burst-only peak.

Questions about this item

What comes in the box and do I need a SATA power cable?

The card draws all power from the PCIe slot so no SATA power cable is required; the package includes the adapter and a low-profile bracket.

Which PCIe slot should I use for the 4-port adapter?

The standard PCIe x1 form factor fits x1, x4, x8 or x16 slots on Intel and AMD motherboards.

What does the 5Gbps rating mean for my external hard disk?

It provides USB 3.0 speeds up to 5Gbps for fast file transfers while remaining backward compatible with USB 2.0 and 1.1 devices.
