The Cudy PE10 is a Gigabit PCI Express network adapter designed to add high-speed wired network connectivity to your desktop computer. This black, compact card installs into a free PCI-E x1 or higher slot on your motherboard, providing an additional Gigabit Ethernet port. It includes a low-profile bracket for compatibility with both standard and small form factor cases, offering installation flexibility. Technically, this adapter auto-negotiates between 10/100/1000 Mbps speeds and supports modern network protocols such as 802.3x Flow Control and 802.3az Energy Efficient Ethernet. The Wake-on-LAN feature allows you to remotely power on or off your computer over the network. It works seamlessly on Windows and Linux platforms thanks to broad operating system support. The operating temperature range of 0°C to 70°C is suitable for most office and home environments. This adapter is ideal for users whose motherboard's built-in Ethernet port is faulty or insufficient. It is also designed for server systems requiring multiple network connections or PCs acting as firewalls/routers (e.g., with software like MikroTik). Its plug-and-play nature allows quick deployment without driver installation (with Windows and Linux kernel support).
