SKU CH-YCF0-TSFB7 MPN MCX75510AAS-NEAT

Single-port 400 Gbps Ethernet card with PCIe 5.0 x16 interface for high-speed server networking

  • Rated speed400Gbs
  • Interface typePCI-Express
  • 400Gbps throughput for high-density server links
  • PCIe 5.0 x16 host interface for reliable data transfer
  • Single OSFP port supports optical fiber over long distances
  • ConnectX-7 architecture built for modern data-centre workloads
  • New condition, first listed by manufacturer in 2025

ConnectX-7 400Gbps OSFP NIC

The NVIDIA MCX75510AAS-NEAT is a single-port 400Gbps Ethernet adapter built on the ConnectX-7 controller. It installs in a PCIe 5.0 x16 slot and uses an OSFP cage for optical fibre connectivity. The card ships with a tall bracket for standard server chassis.

Suited for high-throughput server links

This adapter serves data-centre operators who need one 400Gbps optical link per slot. It does not fit builders who require copper twinax media, multiple ports on a single bracket, or a lower-speed interface.

PCIe 5.0 x16 host interface

The x16 Gen 5 connection supplies the bus bandwidth the 400Gbps port demands. Verify that the target platform provides a full x16 electrical link and an available OSFP-compatible transceiver before ordering.

Questions about this item

Does the MCX75510AAS-NEAT include an OSFP transceiver or cable in the box, or must I purchase them separately?

The card ships with a tall bracket installed; OSFP transceivers and fiber cables are not included and must be sourced separately to match your link distance and fiber type.

How do I choose between the available versions or capacities of the ConnectX-7 400Gbps card?

The MCX75510AAS-NEAT is a single 400Gbps OSFP port model; other ConnectX-7 SKUs differ in port count, connector type or bracket height, so select the SKU that matches your required port density and rack spacing.

What does the 400Gbps headline speed mean once the card is installed in a PCIe 5.0 x16 slot?

The 400Gbps rating is the Ethernet line rate of the single OSFP port; the PCIe 5.0 x16 host interface provides the upstream bandwidth needed to sustain that rate in supported server platforms.
