7 Port PCI-E USB 3.0 Expansion Card, PCI Express to USB3.0 Controller Adapter Converter with 15-Pin SATA Independent Power Supply, SuperSpeed 5Gbps Desktop PCIe USB Expansion Card for External HDD, Ke

This 7-port PCI-E USB 3.0 expansion card is a practical PCIe to USB3.0 converter designed to solve insufficient desktop USB interfaces, ideal for office, gaming and video editing workstations.

Equipped with seven full-speed USB 3.0 Type-A ports, it provides a maximum transfer speed of 5Gbps, greatly accelerating transmission of large-capacity hard disks, 4K videos, raw photos and mass files. Adopting UASP transmission protocol, it cuts down waiting time during batch data copy compared with standard USB3.0 cards.

Different from ordinary PCIe USB cards lacking power supply, this controller integrates a 15-pin SATA power connector to connect your PC power supply directly. It supplies stable sufficient current to each port, avoiding device disconnection, slow reading or identification failure caused by insufficient motherboard power when multiple mechanical hard drives and high-power peripherals are plugged in simultaneously.

The card supports all standard PCI Express slots including X1, X4, X8 and X16, and is fully backward compatible with USB 2.0 and USB 1.1 devices such as keyboards, mice, printers, card readers, USB fans and game controllers. Solid capacitors and built-in overcurrent protection circuits effectively prevent short-circuit damage and overheating during long-time continuous operation.

It features plug-and-play performance for mainstream Windows systems, with driver support for Linux platforms. Standard full-height metal bracket fits most desktop chassis; compact PCB layout saves internal case space. Perfect upgrade accessory for desktops with limited native USB ports to realize seamless multi-peripheral parallel connection.
