Raise wired throughput without replacing your switching infrastructure. The StarTech ST2GPEX 1 Port PCIe Network Card delivers 2.5GbE connectivity through a PCIe host interface, giving desktops and small-form-factor systems a practical path to higher LAN performance for file transfers, imaging, virtualization, and shared storage access. Built on the Realtek RTL8125 chipset, it supports 2.5G, 1G, 100 Mbps, and 10 Mbps operation and is compatible with both 2.5GBASE-T and NBASE-T specifications. That flexibility helps IT teams extend the life of existing cabling, including CAT5e and CAT6a, while improving throughput where 1GbE is no longer enough. IEEE 802.3az and IEEE 802.3u compliance supports efficient operation in always-on environments. Standard and low-profile brackets are included, making the card easier to deploy across tower desktops and compact chassis. For organizations that need a measured upgrade rather than a full network refresh, this adapter offers a cost-effective way to unlock more bandwidth at the edge.
