This is a PCI Express expansion card designed to add two USB 3.0 ports to a desktop computer. It is ideal for users who need faster data transfer speeds and more connectivity options for external devices. The card supports transfer rates up to 5 Gbps, which is significantly faster than USB 2.0, making it suitable for tasks like transferring large files or connecting high-speed peripherals. It is compatible with both full and low profile systems, making it versatile for different PC cases and form factors.
The card uses a native NEC PCI Express host controller chipset, ensuring compliance with USB 3.0 revision 1.0 and Intel xHCI rev0.96 standards. It provides backward compatibility with USB 2.0 and USB 1.0/1.1 devices, allowing users to connect older peripherals without issues. Each USB port can supply up to 900mA of power, which helps in powering external devices without requiring an external power source. This makes it convenient for users who rely on multiple USB-connected devices.
The design includes an optional LP4 Molex power connector, which can be used to provide additional power to the card if needed. This feature ensures stable operation even when powering high-demand devices through the USB ports. The card is easy to install by inserting it into a PCI Express slot on the motherboard and securing it with a screw. No additional software or drivers are required for basic functionality, as it works out of the box with most operating systems.
The card is well-suited for users who need to upgrade their desktop’s connectivity without replacing the entire system. It is particularly useful for professionals who work with large files, such as video editors or photographers, who require fast data transfer speeds. However, it is not compatible with laptops or systems that lack a PCI Express expansion slot.
