Key Features

  • Expand network ports for devices: Inserting a PCIe network card into the PCI Express x1 slot adds an RJ45 port to the host computer. This is a good option for desktop computers with fewer network ports or network ports that cannot connect to a wired network
  • Surfing at Full Speed: Using RTL8125B high-performance Chipset, Combined with the latest 2.5GBase-T Technology, delivers extreme speeds of up to 2.5 Gbps, 2.5x faster than typical Gigabit network card, securing smooth data transmissions for both internet access and local data transmissions. Note: The actual transmission speed is limited by the setting of the device connected
  • Widely compatible:Supports the PXE function,RealWow Technology(Wake on Lan),DSM,PVE,ikuai,unraid6.9.2, OpenWrt ESXI6.7 (Doesn’t support ESXI 7.0). Additionally,supports multiple systems-Windows XP/7/8/10,Linux/DOS/support for Intel-based MacOS 10.7(and above)
  • Unique cooling technology: Top is equipped with an aviation-grade alloy heat sink, With a groove design, which can effectively remove excess heat, and maintain the normal working temperature of the network card.Reducing the risk of hardware failure due to overheating
  • Easy to Install: No external power adapter is required, the ethernet adapter has a built-in self-powered IC, and directly draws power from the motherboard PCI-E slot. In addition, to meet your different needs, we offer both standard (installed) and low-profile brackets for easy installation in standard PC/small computer chassis
