StarTech PR25GR-NETWORK-CARD 2-Port 5Gbps PCIe Network Adapter Card
Overview
The StarTech PR25GR-NETWORK-CARD provides a direct upgrade path for systems lacking multi-gigabit Ethernet capabilities. This adapter card installs into a PCI Express x1 slot, delivering two RJ-45 ports capable of 5Gbps, 2.5Gbps, 1Gbps, and 100Mbps speeds. It's designed for workstations, servers, or NVRs that require increased network throughput for demanding applications like high-resolution surveillance streams, large file transfers, or network-attached storage access. The PR25GR-NETWORK-CARD uses the Realtek RTL8126 chipset for reliable performance.
Compatibility
This adapter card is compatible with systems running Windows 10, 11, Windows Server 2019, 2022, and Linux Ubuntu 20.04 and later. It requires a free PCI Express x1 slot or larger (x4, x8, x16). The integrated RJ-45 ports are standard for network connectivity.
Installation Notes
The card operates within a temperature range of 5°C to 65°C (41°F to 149°F) and requires 10% to 80% non-condensing humidity. It is bus-powered, drawing power directly from the PCIe slot, simplifying installation by eliminating the need for an external power supply. The card is a standard profile design, but a low-profile bracket may be required for slimline chassis (not included).
