This 2.5GBase-T PCIe network adapter adopts mature Realtek RTL8125B controller to upgrade your desktop, mini PC or workstation to 2.5G high-speed wired network without rewiring existing network cables. It automatically matches 2500Mbps, 1000Mbps and 100Mbps bandwidth to adapt different routers, switches and network environments, greatly accelerating large file copying, 4K video streaming and NAS data backup tasks.
Dual mounting brackets are included for flexible installation: standard full-height bracket for regular ATX chassis, and low-profile slim bracket for small form factor SFF, HTPC and rack-mounted equipment. The integrated aluminum cooling heat sink efficiently dissipates chip heat to avoid throttling during heavy network load, ensuring stable 24/7 running for monitoring, storage and server scenarios.
PXE remote boot function is pre-enabled, perfectly suited for enterprise IT deployment, industrial embedded devices and cloud terminal network booting. It complies with IEEE 802.3bz 2.5G standard, supports 9K jumbo frames, 802.1Q VLAN tag and hardware flow control to reduce CPU occupation. Auto cross-over detection eliminates the need to distinguish straight or crossover Ethernet cables.
The single RJ45 port works with Cat5e and above UTP cables up to 100 meters transmission distance. Comprehensive driver packages cover Windows, Linux and macOS systems for smooth deployment on consumer and commercial devices.
