Vszerda PCIe USB 3.0 7-Port Expansion Card
Adds seven USB 3.0 Type A ports via a PCIe x1 slot with 5 Gbps speeds and independent 5 V 2 A power per port
- Add seven USB 3.0 ports to a desktop PC via a single PCIe slot
- Each port has its own solid capacitor for stable 5 V 2 A power delivery
- Works in PCIe x1, x4, x8 or x16 slots without extra power cables
- 5 Gbps theoretical bandwidth moves large files ten times faster than USB 2.0
- Driver-free on Windows 8, 10 and 11; Linux and older Windows supported with installers
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.

商品問答
How many independent power phases does the card use to prevent shortages when all ports are active?
The card uses a 2-phase independent power supply module so each of the seven ports gets dedicated power and does not affect the others.
What chips handle the USB 3.0 controller functions on this card?
The card uses NEC720201 and NEC720210 chips to manage the seven USB 3.0 Type A ports.
Which operating systems can use this card without installing an extra driver?
Windows 8, 10 and 11 work without a separate driver; Windows XP and 7 require a downloaded driver.
