Overview

The Syba SD-PEX24041 is a dual-port Gigabit Ethernet PCI Express x1 network adapter card designed to add two 10/100/1000 Mbps RJ45 ports to a desktop PC.

The card includes a low-profile bracket, making it suitable for small form factor cases. It is an ideal solution for home servers, NAS builds, or any scenario requiring multiple network interfaces.

Connectivity & Compatibility

This NIC uses a PCI Express x1 slot (PCIe 2.1 compliant) and provides two auto-negotiating 10/100/1000 Mbps Ethernet ports. It supports IEEE 802.3, 802.3u, and 802.3ab standards, with crossover detection and auto-correction. The card is officially supported on Windows operating systems (drivers available via Windows Update or Realtek's website). While not officially listed, the Realtek RTL8111 chipset is widely recognized by many Linux distributions, though users may need to install drivers manually.

Product Info

The Syba SD-PEX24041 is an entry-level to mid-range dual-port Gigabit NIC offering excellent value for its price. It competes with similar products from brands like TP-Link and Intel, but at a lower cost. The typical retail price is around ¥6,000 (approx. $40 USD) on Japan. The package includes the card, a low-profile bracket, and a quick installation guide. Warranty varies by seller but is typically one year.

Best Use Cases
