pci-e 2 5gb network card

The StarTech ST2GPEX is a high-performance PCI Express network adapter that delivers 2.5 Gigabit Ethernet speeds over standard Cat5e or better cabling. Leveraging the Realtek RTL8125BG chipset, it supports NBASE-T technology for automatic speed negotiation between 100Mbps, 1Gbps, and 2.5Gbps. This makes it an ideal upgrade for workstations and servers requiring faster network throughput without replacing existing cabling infrastructure.

Designed for easy installation, the card features a PCI Express x1 interface (v2.0) and includes both standard and low-profile brackets for use in various chassis sizes. It is compatible with major operating systems including Windows, Linux, and macOS. The ST2GPEX supports jumbo frames up to 9K, VLAN tagging, and Wake-on-LAN, making it suitable for demanding applications like video editing, large file transfers, and virtualization.
