Green PCIe x1 card with four USB 3.0 ports and two metal brackets

Vszerda

Vszerda U3-101 4-port PCIe x1 USB 3.0 expansion card with 80/120mm bracket

SKU CH-R51C-FHXG5

Adds four USB 3.0 ports via a PCIe x1 slot with low-profile and standard brackets included

  • Add four USB 3.0 ports via a single PCIe x1 slot
  • Each port delivers up to 5 Gbps SuperSpeed data transfer
  • Includes both low-profile and standard brackets for flexible fit
  • Powered by SATA or IDE connector for stable 900 mA per port
  • Compatible with Windows 7, 8, 10 on 32-bit and 64-bit systems

Four USB 3.0 ports via PCIe x1

The Vszerda U3-101 adds four external USB 3.0 ports to a desktop or server through a single-lane PCI Express Gen2 slot. Each port delivers up to 5 Gbps SuperSpeed transfer rates while maintaining backward compatibility with USB 2.0 and 1.1 devices. The card requires the NEC USB 3.0 driver to be installed on Windows 7, 8 or 10 before use.

Low-profile and standard brackets included

A 9.5 mm low-profile bracket and a full-height bracket ship in the box, letting the card fit either slim or standard chassis without extra parts. Power is drawn from an internal SATA or IDE connector, supplying 900 mA at 5 V to every port so bus-powered peripherals run reliably. The green PCB weighs 0.05 kg and measures 5.04 by 4.09 by 1.06 inches.

Upgrades systems lacking native USB 3.0

This card targets older motherboards that only offer USB 2.0 headers, instantly adding four 5 Gbps ports for external drives, docks or high-speed cameras. It is not suited for builds that need more than four ports or require internal USB 3.0 headers for front-panel connectors. The single PCIe x1 link caps aggregate bandwidth at Gen2 speeds.

Questions about this item

What practical throughput does the PCIe x1 Gen 2 interface cap this card at?

The single-lane PCIe 2.0 link limits total bandwidth to 5 Gbps, which is the maximum aggregate speed shared across all four USB 3.0 ports.

Which bracket sizes are included so the card fits my chassis?

The box supplies both a 9.5 mm low-profile bracket and a standard 120 mm bracket for full-height slots.

How do I power the card and what step do builders often miss?

Connect either a SATA or IDE power plug to the onboard header; the driver must be installed before the ports will enumerate.
