PCIe 3.1 X1 5G PCIE Network Card, Realtek RTL8126 Chip Multi-Gigabit RJ45 LAN NIC, Support 5000Mbps/2500Mbps/1000Mbps for Desktop Motherboard

This PCIe 3.1 x1 5G multi-gigabit network card adopts industry-leading Realtek RTL8126 controller chip, delivering ultra-fast wired network speed up to 5000Mbps, 5 times faster than traditional 1Gbps Ethernet cards, perfectly upgrading wired network performance for desktops, workstations and small servers.

It complies with IEEE 802.3bz NBASE-T standard, supporting automatic speed negotiation of 5Gbps, 2500Mbps, 1000Mbps, 100Mbps and 10Mbps. No need to replace existing CAT5e/CAT6 network cables, directly realize high-speed large file transmission between PC and NAS, cloud storage, video editing workstations and local area network devices.

Designed with PCIe 3.1 x1 bus interface, it is fully compatible with PCIe x1, x4, x8, x16 slots of all mainstream AMD and Intel motherboards without occupying high-speed PCIe x16 graphics slots. Integrated thick aluminum heat sink efficiently dissipates heat generated by the chip during continuous high-load transmission, effectively avoiding network lag, disconnection and overheating failure.

Comes with full-height standard bracket and low-profile half-height bracket as accessories, supporting installation in standard ATX chassis, MATX mini hosts, HTPC and compact small servers. Built-in hardware acceleration functions including TCP/UDP checksum offload, VLAN tagging, Wake-on-LAN and 9K jumbo frames, greatly reducing CPU occupancy during data transmission.

Wide system compatibility with Windows 7/8/10/11, Linux and virtual machine systems, plug-and-play with official driver support. Widely used for 4K/8K video post-production, large-capacity file storage access, online gaming, enterprise office network expansion and home high-speed NAS connection scenarios.
