SKU CH-WV9H-KEN88

Adds four 5Gbps USB 3.0 ports — three external and one internal header — with a VL805 controller and 4-pin auxiliary power for stable high-draw devices

  • Add four 5 Gbps USB ports with one VL805 controller
  • Stable long-run data transfer via mature VL805 chip
  • Extra 4-pin power feeds high-draw drives reliably
  • Fits any PCIe x1, x4, x8 or x16 slot
  • Works on Windows and Linux with USB 2.0/1.1 gear

PCIe to 4-Port USB 3.0 Card

The SMUGDESK PCIe expansion card adds four 5Gbps USB 3.0 ports to a desktop computer. Three external Type-A ports and one internal header connect storage drives and peripherals. The card fits PCIe X1, X4, X8 or X16 slots. It works with Windows and Linux systems.

VL805 Chip with 4Pin Auxiliary Power

The onboard VL805 controller delivers stable data transmission during long continuous workloads. A 4Pin power connector supplies extra current for high-power USB hard drives. This replaces a basic unpowered adapter when attached devices exceed the slot power budget. The upgrade is worth it for multi-drive arrays or mining accessories.

Sustained Load Behaviour

The mature VL805 chip maintains throughput over extended transfer sessions without thermal throttling. Auxiliary power prevents voltage sag when several drives spin up together. Backward compatibility with USB 2.0 and 1.1 ensures legacy devices remain functional. The card targets builders who need reliable expansion, not portable or laptop users.

Questions about this item

Does this card need a PCIe x1 slot and a 4-pin power connector?

Yes, it installs in any PCIe x1, x4, x8 or x16 slot and includes a 4-pin auxiliary power connector for high-draw USB devices.

Do I need to install drivers for the VL805 chip on Windows or Linux?

No separate driver is required; the VL805 controller is supported natively by modern Windows and Linux kernels, so the four 5 Gbps ports appear automatically after boot.

Will the internal USB 3.0 header replace a front-panel connector that uses the 19-pin layout?

The card provides one internal USB 3.0 header (19-pin) that connects directly to a compatible front-panel or drive-bay module, adding a fifth 5 Gbps port inside the chassis.
