4-Port USB 3.0 PCIe Expansion Card, 5Gbps Super Speed Self-Powered PCI Express Hub Adapter for Desktop PC, Compatible Windows XP/Vista/7/8/8.1/10 Server 32&64 Bit, No Extra Power Required

This PCI Express USB 3.0 expansion card supplies four high-speed USB 3.0 ports to resolve the shortage of built-in motherboard USB interfaces, ideal for office PCs, workstations and small servers.

All ports follow USB 3.0 Gen1 standard with maximum 5Gbps transmission speed, drastically shorten file transfer time for flash drives, portable hard disks, memory card readers and digital cameras, and fully backward compatible with USB 2.0 / USB 1.1 peripherals.

Featuring integrated self-powered technology, the card draws sufficient power directly through PCIe slot without connecting extra power supply cables, simplifying installation and tidying internal chassis wiring. No cumbersome power wiring is required during setup.

It achieves outstanding system adaptability, covering all mainstream Windows systems including Windows XP, Vista, 7, 8, 8.1, Windows 10 and corresponding server versions, both 32-bit and 64-bit editions. After installing matched supporting drivers, the card runs stably without complicated configuration.

The universal PCIe X1 physical slot can be mounted on any idle expansion slot of ATX, MATX and mini ITX motherboards. Reinforced full-height metal bracket locks the card tightly inside chassis to prevent loose contact caused by long-term vibration. It is a cost-effective expansion choice for multi-device desktop hosts and entry-level servers.
