Product overview
The Supermicro dual-socket LGA4189 (3rd gen Intel Xeon scalable) E-ATX Server motherboard, Intel C621A chipset, 16x DDR4 DIMM, dual GbE (intel i210) is supplied under part number MBD-X12DAI-N6-O. A replacement board arrives without the service tag, licence bindings and BIOS settings of the one it replaces, and iDRAC or iLO entitlements have to be re-applied. The chipset here is C621A. We flag what has to be re-entered before you start the swap.
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.

What you get ordering this from us
Ordered by part number
MBD-X12DAI-N6-O is what is quoted and MBD-X12DAI-N6-O is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Generation and socket confirmed
A board from an adjacent generation will not take the same CPUs; we check the pairing against your service tag.
Post-swap checklist supplied
Service tag, licence bindings and BIOS settings do not travel with the board, and we tell you what has to be re-entered.
Questions buyers ask about this part
- Is MBD-X12DAI-N6-O genuine and is the warranty intact?
- Yes — new and sealed, with the Supermicro warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
- Will MBD-X12DAI-N6-O work in my server?
- Send the service tag and tell us which CPUs and DIMMs you are moving across. Boards are matched by generation, socket and firmware revision, and an adjacent generation will not take the same processors.
- Do you accept purchase orders and quote at volume?
- Yes — POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.
