Four-port USB 3.0 add-in card for desktop PCs

This PCIe 2.0 x1 card adds four Type-A USB 3.0 ports running at 5Gb/s. It uses the NEC uPD720201 chipset and draws power from the slot, so no extra power cable is required. The card fits standard and low-profile brackets for small-form-factor cases.

Sustained transfer with UASP support

The board supports the UASP protocol, which the supplier says can accelerate SSD read and write speeds by 70% over traditional USB 3.0 bulk endpoints. Backward compatibility with USB 2.0 and 1.1 keeps older peripherals functional at their native rates.

Simple installation with one common pitfall

The card installs in any PCIe x1, x4, x8 or x16 slot and works without drivers on Windows 98SE through Vista; newer Windows versions typically load a generic driver automatically. The only frequent issue is that the supplied low-profile bracket must be swapped for the full-height bracket on standard towers, otherwise the rear bracket will not align with the case cut-out.
