Socket P+ Xeon server board

The Supermicro MBD-X12SPO-F-O is an ATX server motherboard built for the single LGA-4189 (Socket P+) platform. It accepts 3rd Gen Intel Xeon Scalable processors up to 270 W TDP and uses the Intel C621A chipset. Eight 288-pin DDR4-3200 slots support up to 2 TB of 3DS ECC RDIMM or LRDIMM, plus Optane persistent memory. Onboard ASPEED AST2600 BMC provides remote management graphics.

Memory-dense single-socket builds

This board suits builders who need maximum DDR4 capacity in a single-socket design, with eight slots, ECC support and Optane compatibility. It also provides ten SATA3 ports, RAID 0/1/5/10 and dual 1 GbE LAN for storage-heavy workloads. Buyers requiring dual-socket scaling, higher-speed networking or more than one PCIe 4.0 x16 slot should consider other platforms.

One PCIe 4.0 x16 slot

The expansion layout centres on a single PCI Express 4.0 x16 slot, limiting the board to one full-width accelerator or GPU. Two M.2 slots (2280/22110 M-Key) accept SATA or PCIe 3.0 x4 drives, while four NVMe devices can be added via SlimSAS connectors. Rear I/O offers three USB 3.2 Gen1, two USB 2.0, one COM and one VGA port.

Questions about this item

How much power can the LGA-4189 socket deliver to a 3rd Gen Xeon running continuously?

The socket supports CPUs up to 270 W TDP, so sustained load will draw at most that much from the board's power phases.

Which components are not included and must be supplied separately for the board to post?

You need a 3rd Gen Intel Xeon Scalable processor, DDR4-3200 ECC RDIMM or LRDIMM modules, and at least one storage drive.

Will my existing SATA SSDs and hard drives work with the ten SATA3 ports on this board?

Yes, the Intel C621A controller provides ten 6 Gbps SATA3 ports with RAID 0, 1, 5, 10 support for legacy drives.
