Quanta S52Q-1USL Server Motherboard vs Supermicro H12SSL-CT Server Motherboard

The Supermicro H12SSL-CT is the safer buy for most people: it is a standard ATX board with documented EPYC 7003/7002 support, dual 10GBase-T, onboard SAS3 and a 4.8/5 rating from 91 owners. The Quanta S52Q-1USL is a proprietary OEM board with 16 DIMM slots, which suits high-capacity memory builds but comes with no retail documentation, no integrated networking or storage listed, and a chassis fit that is not standard ATX. Pick the Supermicro unless you specifically need the extra memory slots and can confirm the board fits your chassis and BIOS.

• Choose the Quanta S52Q-1USL if you need 16 DDR4 slots for a high-capacity memory build and can verify the board fits your OEM chassis and boots your EPYC chip.
• Choose the Supermicro H12SSL-CT if you want a standard ATX board with documented EPYC 7003/7002 support, dual 10GBase-T, onboard SAS3 and a track record with owners.
