Frequently Asked Questions

What does the -O suffix indicate?

The -O suffix on Supermicro part numbers typically indicates an open-box or alternate OEM configuration of the standard motherboard. The hardware is the same H12DSI-NT6 — verify specific packaging details with Supermicro or the seller before ordering.

What is the difference between MBD-H12DSI-NT6-O and MBD-H12DSI-NT6-B?

Both are OEM/alternate packaging variants of the H12DSI-NT6. The -O typically indicates open-box or alternate OEM configuration while -B indicates bulk packaging. Verify specific differences with Supermicro before ordering.
