Frequently Asked Questions

What is the difference between H12SSL-I and MBD-H12SSL-I?

H12SSL-I is the retail boxed version, while MBD-H12SSL-I is the bulk/OEM version (MBD prefix = motherboard, OEM packaging). Both are the same motherboard — select based on your packaging preference.

What is the difference between H12SSL-I and H12SSL-NT?

The H12SSL-NT adds onboard SAS connectivity (via an integrated SAS controller) in addition to SATA — making it suited for deployments requiring direct SAS drive connectivity without a separate HBA.

The Supermicro H12SSL-I delivers a single-socket SP3 ATX server platform for AMD EPYC 7002/7003 with DDR4 ECC memory, PCIe 4.0, SATA, M.2, and IPMI — a versatile 1P EPYC server motherboard for virtualization, AI/ML, and data center deployments.
