Supermicro LGA 1200 Server Board

The Supermicro MBD-X12STH-F-O is a Micro ATX server motherboard built for the LGA 1200 socket. It supports single 10th Gen Intel Pentium or Xeon E-2300 processors up to 95W TDP. The Intel C256 chipset provides four 288-pin DDR4 3200 slots with ECC support up to 128GB.

Who This Fits And Who It Does Not

This board suits builders needing a compact server platform with ECC memory and eight SATA 6.0Gb/s ports. It also provides a PCIe 4.0 x16 slot and dual gigabit LAN. Buyers who want more storage interfaces or multiple CPU sockets should look elsewhere.

The Spec That Decides Fit

The LGA 1200 socket defines which processors install. Only the listed 10th Gen Intel Pentium and Xeon E-2300 CPUs are supported. Verify your processor matches this socket and generation before purchase.
