Product overview
The NVIDIA/Mellanox ConnectX-5 dual port 25GbE SFP28 PCIe 3.0 network Adapter is supplied under part number MCX512A-ACAT. An adapter's driver and firmware support on the host operating system decides whether it is usable, not the slot it fits. This card is 25GbE. Tell us the OS and hypervisor version and we will confirm support before it ships.
If the part is wrong for your platform we will say so and suggest the one that is, which is cheaper for both of us than a return.

Questions buyers ask about this part
- Is MCX512A-ACAT genuine and is the warranty intact?
- Yes. It ships new in NVIDIA/Mellanox packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
- Will MCX512A-ACAT work in my server?
- Send us the server model or service tag and we will confirm before you order. Part numbers alone do not always settle it — firmware revision and platform generation matter, and this is the check that prevents a return.
- Do you accept purchase orders and quote at volume?
- Yes. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.
