Four USB 3.0 ports for desktop expansion

This PCIe card adds two USB-C and two USB-A ports to a desktop computer through a single PCI Express x1 slot. It targets builders and IT professionals who need more high-speed connections for external drives, VR headsets, cameras or peripherals without replacing the motherboard.

Upgrades systems limited to USB 2.0 or fewer ports

The jump is worth it when existing front-panel or rear I/O cannot handle multiple SuperSpeed devices at once. The card delivers up to 5.0 Gbps per channel and supports UASP for faster enclosure transfers, while remaining backward compatible with USB 2.0 and 1.x gear.

Bandwidth shared across the PCIe 2.0 x1 link

Total throughput cannot exceed the single-lane PCIe 2.0 ceiling, so simultaneous heavy transfers on all four ports will contend for that bandwidth. The card draws power from the slot itself with a 5V/3000mA limit, so very high-draw devices may need external power.

Questions about this item

Will the 4.92 x 4.06 x 1.06 inch board fit in a PCIe x1 slot?

Yes, the card fits PCI Express x1, x4, x8 or x16 sockets and complies with PCI Express Specification 2.0, so any standard x1 slot will accept it.

Which step do people skip when installing the card and the CD driver?

Many forget to shut down the PC, unplug the power supply, and remove the case before pushing the card into the PCIe socket and tightening the supplied screws.

When will the on-board NEC chipset or the 5 V / 3000 mA power circuit need replacement?

The card has no user-serviceable parts; if a port fails or power delivery drops, the entire expansion card must be replaced.
