Supermicro MBD-X11SCA-O LGA 1151 C246 DDR4 ATX server motherboard

Server motherboard for Xeon and Core CPUs

The Supermicro MBD-X11SCA-O is an ATX server board built around the Intel C246 chipset and the LGA 1151 socket. It accepts Xeon E-2100 and E-2200 processors as well as 8th and 9th generation Core i9, i7, i5, i3, Pentium and Celeron chips. Four DDR4 UDIMM slots support up to 64 GB of ECC or non-ECC memory at 2666 MHz.

Suits builders who need dual gigabit LAN and RAID

Two Intel gigabit controllers provide redundant network links, while eight SATA 6.0 Gb/s ports with RAID 0, 1, 5 and 10 cover local storage arrays. The board lacks onboard video unless a Xeon E-21XXG processor is installed, so a discrete graphics card is required for most CPUs. Buyers who want more storage lanes or integrated graphics on every CPU should look elsewhere.

Sustained load stays within 95 W CPU limit

The socket is rated for processors up to 95 W TDP, so thermal output remains predictable during long compute runs. PCI Express slots operate at x16 or dual x8 for the primary pair, plus one x4 and one x1 slot, keeping bandwidth steady for add-in cards. Dual LAN and SATA controllers maintain throughput without saturating the chipset.
