Supermicro MBD-X12SAE-5-O server motherboard

Server motherboard for 11th Gen Intel

The Supermicro MBD-X12SAE-5-O is an ATX server motherboard built around the Intel W580 chipset and LGA 1200 socket. It supports 11th Generation Intel Core i5, i7 and i9 processors plus Intel Xeon W-1300 series CPUs up to 125W TDP. The board targets workstation and entry-server builds that need ECC memory and dual LAN in a standard form factor. Buyers who want more storage expansion than four SATA ports and three M.2 slots should look elsewhere.

Memory and storage layout

Four 288-pin DDR4 slots accept unbuffered ECC or non-ECC UDIMMs up to 128GB total at 3200MHz. Storage connectivity covers four SATA 6.0Gb/s ports with RAID 0, 1, 5 and 10 plus three M.2 sockets: one PCIe 4.0 x4 and two PCIe 3.0 x4, all M-keyed for 2280 and 22110 modules with RAID 0 and 1 support. Note that RAID 5 on the M.2 interface applies only to Intel storage devices.

Installation and common issues

Dual Intel LAN (I225-V at 2.5Gbps and I219-LM at 1Gbps) and a Realtek ALC888S audio codec are integrated on the rear I/O alongside four USB 3.2 Gen2 Type-A, two USB 3.2 Gen2x2 (one Type-C), two USB 3.2 Gen1 and two USB 2.0 headers. Expansion includes two PCIe 4.0 x16 slots configurable as 16/0 or 8/8 plus two PCIe 3.0 x1 slots. Builders should verify case clearance for the ATX footprint and confirm CPU cooler mounting for the LGA 1200 socket before purchase.
