PCIe X1 Gigabit Ethernet Network Card, Realtek RTL8111H Chip, 6-Port Copper RJ45 LAN Adapter for Server Desktop PC, 10/100/1000Mbps Auto-Negotiation PCI Express Gigabit Expansion Card, Alternative 4-P

This PCIe X1 multi-port gigabit Ethernet expansion card is equipped with mature Realtek RTL8111H control chip, offering stable high-speed wired network expansion for desktop hosts, small workstations and entry-level servers. Two specifications are optional: 4-port and 6-port RJ45 copper network ports, which help users expand multiple independent network links to meet multi-network access, network isolation, soft routing, NAS file transmission and monitoring host networking demands.

Each RJ45 port supports 10/100/1000Mbps auto-negotiation, automatically matching the access speed of switches and optical transceivers. The gigabit bandwidth realizes ultra-fast large file copying, 4K video stream transmission and low-latency data interaction, effectively avoiding network congestion when multiple devices transmit data simultaneously. Gold-plated network ports and PCIe contacts reduce signal loss and resist oxidation, maintaining stable connection for long-term use.

The card adopts universal PCIe X1 slot design, which can be inserted into any PCIe X1, X4, X8 or X16 slot of mainstream desktop and server motherboards without occupying high-speed graphics card slots. Independent aluminum heat sink is configured for each chip to quickly export heat generated during high-load transmission, preventing performance throttling caused by overheating.

Built-in ESD surge protection circuit for each network port can resist static electricity and instantaneous voltage surges in complex cabinet environments, protecting the card and connected network equipment from damage. It supports common network functions such as VLAN partition, jumbo frame, wake-on-LAN and link aggregation, and is fully compatible with Windows, Linux and server operating systems.

Low-profile bracket is included for small chassis installation, while standard full-height bracket fits ordinary tower cases. Plug-and-play after installing the official driver, widely applicable to home soft routing, enterprise office multi-network hosts, storage servers, video surveillance workstations and other scenarios requiring multi-gigabit network expansion.

Package Includes: 1 x PCIe X1 Gigabit Ethernet Card (4-port or 6-port RTL8111H version), Full-height & Low-profile Brackets, Driver CD, User Manual
