Professional 10G Network Card with PCIe x4 Bandwidth

Built on the AMD B650 SouthBridge chipset (ASMedia Promontory 21), this card turns motherboard chipset functions into a standard PCIe expansion device. A single PCIe 4.0 x4 upstream link expands into four Realtek RTL8127 10GbE Ethernet ports (RJ45), with no motherboard PCIe bifurcation required. Each port auto-negotiates 10G/5G/2.5G/1G/100M, and all four run at full speed simultaneously. Heatsink-plus-fan active cooling holds the whole card at approx. 47–50°C under high load, for soft routers,firewalls, NAS, storage servers, virtualization platforms, high-end workstations and enterprise networks.
