PCIe x4 Gen 4.0 network controller card with one 10G SFP+ port, featuring the REALTEK RTL8127 chipset, low power consumption, and passive cooling

A multi-gigabit network card supporting speeds up to 10G that provides fast and reliable Ethernet connectivity for servers and workstations. It supports multi-speed networks and offers broad compatibility with operating systems. This new RTL8127 chipset offers two major advantages: low power consumption and moderate heat generation.

Note: This card is designed for use on a Gen 4.0 x1 port. If you use it on a Gen 3.0 port, it will function but its throughput will be halved.
