Vszerda 8-Port PCIe USB 3.2 Expansion Card 4C 4A 10Gbps

8-Port PCIe USB 3.2 Expansion Card

The Vszerda add-on card adds eight USB 3.2 Gen 2 ports to a desktop system through a single PCI Express x1 slot. Four ports are USB Type-C and four are USB Type-A, letting you connect keyboards, mice, external drives, webcams, printers, scanners, game controllers and VR headsets. It fits PCIe x4, x8 or x16 sockets and works with Windows 7 through 11, macOS 10.8.2 and later, Linux, Ubuntu and unRAID. Driver-free on Windows 10 and 11, macOS and Linux; Windows 7 requires the supplied driver.

20 Gbps aggregate bandwidth split across two

The card provides two independent 10 Gbps channels. One USB Type-C port and three USB Type-A ports share the first 10 Gbps pool, while the remaining four ports share the second 10 Gbps pool. A single port can reach the full 10 Gbps when it is the only active device on its channel, but simultaneous transfers on multiple ports divide the available bandwidth. The adapter handles data only; it does not support Power Delivery fast charging, video output or Thunderbolt protocol.

PCIe x1 slot limits total throughput to one lane

Although the card presents 20 Gbps of USB bandwidth, the host connection is a single PCI Express lane. On a PCIe 2.0 platform that lane caps at 5 GT/s, on PCIe 3.0 at 8 GT/s and on PCIe 4.0 at 16 GT/s, so the bus can become the bottleneck before the USB controllers saturate. The card is compatible with PCIe 2.0, 3.0 and 4.0 motherboards, but builders who need sustained 20 Gbps across all eight ports simultaneously should verify their platform's single-lane throughput.
