YEPLOOK 4 Port USB 3.0 PCI-E X1 Expansion Card

SKU CH-Z10M-0KT5R

Adds four USB 3.0 ports via a PCIe x1 slot using a VIA chipset with independent power and plug-and-play setup

  • Product typePCI to USB Card
  • Adds four USB 3.0 ports via PCIe x1 slot
  • 5 Gbps transfer speed with VIA chipset
  • Independent power supply for stable operation
  • Plug-and-play installation, no drivers needed

Four USB 3.0 ports on a PCIe x1 slot

This YEPLOOK expansion card adds four USB 3.0 ports to a desktop through a single PCIe x1 slot. It uses a VIA chipset to deliver 5 Gbps bandwidth per port. An independent power connector supplies stable current to attached devices. The card works with plug-and-play installation on supported operating systems.

Fits any free PCIe x1 lane

The card occupies one PCIe x1 slot and is compatible with larger PCIe slots as well. It requires an available internal power connector for the independent supply. Builders who need more than four additional USB ports or who lack a spare PCIe slot should consider alternative expansion options.

Questions about this item

How does the VIA chipset handle sustained 5 Gbps throughput across all four ports?

The VIA controller manages independent 5 Gbps channels for each port, preventing bandwidth contention when multiple devices transfer data simultaneously.

Does the independent power supply reduce heat on the card during continuous operation?

The separate power feed delivers current directly to the USB ports, so the PCIe slot only carries signalling and the card stays cooler under all-day loads.
