Bring multi-Gig connectivity to systems that need more throughput than 1 GbE can deliver, while keeping the cabling you already have in place. This StarTech 2-port network card uses the Realtek RTL8126 controller to support 5G, 2.5G, 1G, 100M, and 10M speeds through auto-negotiation. That makes it a practical fit for teams upgrading access layers, lab systems, or performance workstations without moving to new cable runs. The PCI Express interface supports a wide range of slot sizes, including x1, x2, x4, x8, and x16, which simplifies deployment across Intel- and AMD-based systems. Driver auto-install behavior in most major operating systems helps reduce setup time, while Windows, Windows Server, and Linux compatibility supports mixed environments. For network control, the card supports 9K jumbo frames, VLAN tagging, and Wake-on-LAN. Those features matter when packet efficiency, segmentation, and remote power management are part of the design. TAA compliance adds procurement value for public sector and regulated buyers who need a card that fits both technical and sourcing requirements. At 0.25 lb, it is a compact way to add serious bandwidth where it counts.
