Vszerda PCIe USB 3.0 7-Port Expansion Card

Seven-port PCIe USB 3.0 expansion card

The Vszerda add-on card brings seven USB 3.0 Type-A ports to a desktop PC through a single PCIe slot. It targets builders who need more high-speed connections for external drives, cameras or peripherals without opening the case for internal hubs. The board fits PCIe x1, x4, x8 or x16 slots and works with 32-bit and 64-bit Windows 11, 10, 8, 7, XP and Linux; macOS is not supported.

Independent power per port for stable operation

A two-phase power module supplies each port separately so one device’s draw cannot starve another. No external power cable is required, yet every port can deliver 5 V at 2 A thanks to NEC 720201 and 720210 controllers backed by seven solid capacitors. Backward compatibility with USB 2.0 and 1.1 lets older gear work without extra adapters.

Sustained throughput with low-impedance capacitors

The conductive-polymer solid capacitors keep ESR low, so voltage stays steady during long file transfers or continuous video offloads. Each port maintains its own capacitor, preventing cross-port interference when multiple devices stream data at once. The design avoids thermal throttling by spreading the load across independent power paths.
