UGREEN US230 Gigabit PCI Express Network Adapter 1000Mbps – UG-30771

The UGREEN US230 Gigabit PCI Express Network Adapter (UG-30771) is an internal Ethernet expansion card designed to add reliable high-speed wired network connectivity to compatible desktop computers. Equipped with a Gigabit RJ45 Ethernet port, it supports automatic 10/100/1000Mbps network speeds for internet access, file transfers, streaming, gaming, office networking, and other bandwidth-intensive applications.

The network adapter installs into a compatible PCI Express slot and can be used with PCIe x1 as well as larger compatible PCIe slots. This makes it a practical solution for desktop PCs with a damaged onboard Ethernet port, systems without integrated Gigabit Ethernet, or computers requiring an additional wired network interface.

Powered by a Realtek Gigabit Ethernet chipset, the US230 supports common Ethernet standards and networking features including auto-negotiation, Auto MDI/MDIX, Wake-on-LAN, VLAN tagging, and Jumbo Frames.

Product Features

Gigabit Ethernet up to 1000Mbps

Supports 10/100/1000Mbps Ethernet, providing high-speed wired networking for compatible Gigabit routers, switches, and network infrastructure.

PCI Express Interface

Installs directly into a PCIe x1 slot and can also operate in compatible PCIe x4, x8, and x16 slots.

RJ45 Ethernet Port

Features 1 × RJ45 network interface for connecting the desktop computer directly to routers, switches, network outlets, and other Ethernet equipment.

Realtek Gigabit Chipset

Uses a Realtek Gigabit Ethernet controller designed to provide reliable and efficient wired network connectivity.

Auto-Negotiation

Automatically detects and negotiates compatible 10Mbps, 100Mbps, or 1000Mbps network speeds according to the connected networking equipment.

Auto MDI/MDIX

Supports Auto MDI/MDIX, eliminating the need to distinguish between straight-through and crossover Ethernet cables in compatible installations.

Wake-on-LAN Support

Supports Wake-on-LAN (WoL), allowing compatible computers to be remotely awakened through the network when correctly configured.

Jumbo Frame Support

Supports Jumbo Frames up to 9KB, useful for compatible local networks handling large data transfers.

VLAN Support

Supports IEEE 802.1Q VLAN tagging, making the adapter suitable for compatible managed network environments.

Standard & Low-Profile Installation

Includes a low-profile bracket in addition to the standard bracket, allowing installation in compatible full-size and compact desktop cases.
