Two SuperSpeed USB 3.0 Ports

This PCI Express expansion card adds two external USB 3.0 ports to a desktop computer. It uses the NEC uPD720202 controller and fits a standard-profile slot with a low-profile bracket included. The card draws auxiliary power through an LP4 connector.

Upgrade from USB 2.0 Header Limits

The card replaces reliance on internal USB 2.0 headers or slower add-in cards by providing native 5 Gbps throughput. The jump is worthwhile when external drives or peripherals need the higher signalling rate and UASP support for reduced protocol overhead.

5 Gbps Bandwidth per Port

Each port delivers up to 5 Gbps and supports the USB Battery Charging 1.2 specification for faster device charging. Headroom is sufficient for external SSDs and high-capacity hard drives; sustained write workloads that exceed the PCIe lane allocation will saturate the link.

أسئلة حول هذا المنتج

Will this card fit in a standard PCI Express slot and does it include a low-profile bracket?

Yes, the card uses a standard PCI Express x1 slot and ships with a low-profile bracket for half-height cases.

Do I need to connect the LP4 power connector on the card for the USB ports to work?

The LP4 connector must be plugged into a spare power-supply lead; without it the controller cannot deliver the 5 Gbps data rate or the battery-charging current.

Which chipset does this card use and will it need a driver update later?

The card uses the NEC uPD720202 controller; Windows 10 and later include native support so no separate driver install is required.
