PCIe 3.0 X4 USB 3.2 Gen 2x2 Expansion Card, 20Gbps Type-C PCI Express Controller Adapter with SATA Power Supply, Full-Profile & Low-Profile Brackets Included for Desktop Motherboard

This PCIe 3.0 X4 USB 3.2 Gen 2x2 add-on card is a high-speed interface upgrade tool for desktops, specially designed for video creators and storage enthusiasts. It provides a single Type-C port supporting 20Gbps transmission speed, greatly shortening the time of copying large 4K/8K video files and raw image materials, far exceeding the transmission limit of ordinary 10Gbps USB ports.

Adopting PCIe 3.0 X4 full-lane transmission, the card will not cause bandwidth loss when running at full speed, effectively matching high-performance portable solid-state drives. Different from expansion cards only powered by PCIe slots, this product reserves an independent SATA 15-pin power supply port. After connecting the host power supply, it can output stable current to avoid device disconnection and speed drop caused by insufficient power when using high-load peripherals.

Two types of mounting brackets are delivered together. The standard full-height bracket is suitable for conventional large chassis, and the low-profile thin bracket can be installed on slim small hosts, meeting diversified assembly demands. It supports UASP accelerated transmission protocol to further improve actual read-write performance, and is backward compatible with USB 3.2 Gen1, USB 2.0 and USB 1.1 devices, realizing reuse of old peripherals.

The installation process is simple without complicated wiring configuration. Windows 10 and above systems support direct plug and play, and driver files are provided for Windows 8 and Linux systems. Built-in over-current and over-voltage protection circuits to effectively protect the motherboard and external storage equipment during long-term continuous operation, ideal for editing workstations, storage servers and DIY high-performance gaming desktops.
