Our take on the Supermicro MBD-A1SAI-2750F-O A1SAI-2750F Socket FCBGA-1283 System on Chip Chipset Mini-ITX System Board (Motherboard) Supports Atom C2750 DDR3 4x DIMM

The Supermicro A1SAI-2750F is a Mini-ITX motherboard with an Intel Atom C2750 soldered on, so board and CPU arrive as one unit. The eight-core Atom runs fanless-friendly and draws little power, which suits always-on boxes like firewalls, NAS builds and small servers. It has four DDR3 DIMM slots, dual Gigabit Ethernet and six SATA ports, more expandability than most Atom boards of its generation. The catch is age: the C2750 is a 2013-era chip, DDR3 is obsolete, and the board has no PCIe x16 slot, so it is a budget platform for light workloads rather than a modern general-purpose board.

Pros
  • Eight-core Atom C2750 with low power draw
  • Four DDR3 DIMM slots, up to 64GB
  • Six SATA ports and dual Gigabit Ethernet on board
  • Mini-ITX size fits small cases
  • Fanless-capable design for silent 24/7 use
Cons
  • Aging Atom C2750 with modest single-thread speed
  • DDR3 only, no modern memory support
  • No PCIe x16 slot, so no discrete GPU or fast add-in card
  • IPMI and remote management are limited compared with Supermicro's Xeon boards
  • Used units may carry the C2000 clock-signal flaw

What reviewers say

Owner reports center on homelab and firewall use. People like the low power draw, the four DIMM slots and the six SATA ports for the size. The main complaints are the slow single-core performance and the age of the platform.

What people mention
  • PerformanceMixedOwners say multi-core throughput is fine for routing and file serving, but single-thread speed is slow by modern standards.
  • Power drawPraisedUsers report low idle consumption, which makes it a good fit for always-on firewall and NAS duty.
  • MemoryMixedFour DIMM slots are welcome, but DDR3 is old and getting harder to buy.
  • ReliabilityCriticisedSome owners report the known Atom C2000 clock-signal defect that can brick the board after a few years.
  • ConnectivityPraisedSix SATA ports and dual Gigabit Ethernet are seen as generous for the form factor.

About the Supermicro MBD-A1SAI-2750F-O A1SAI-2750F Socket FCBGA-1283 System on Chip Chipset Mini-ITX System Board (Motherboard) Supports Atom C2750 DDR3 4x DIMM

The Supermicro A1SAI-2750F-O (MBD-A1SAI-2750F-O) is a Mini-ITX motherboard with an Intel Atom C2750 processor.

The board is built around an Atom processor that balances low energy consumption with processing capability. It is intended for edge computing, digital signage and small-form-factor servers, including 24/7 operation in space-constrained environments. It includes integrated storage and networking connectivity to simplify system integration.

Questions and answers

Is the CPU soldered on or socketed?
It is soldered. The Atom C2750 is fixed to the board on an FCBGA-1283 package, so there is no CPU upgrade path.
How much RAM does it support?
Four DDR3 DIMM slots, up to 64GB total with ECC or non-ECC UDIMMs, depending on the modules used.
Can it run pfSense or OPNsense?
Yes. The dual Intel Gigabit NICs and low power draw make it a common choice for router and firewall builds.
Does it need a CPU cooler?
It ships without a cooler. The C2750 can run with a passive heatsink in a ventilated case, but many builds add a small fan for safety.
What is the C2000 clock-signal issue?
An erratum in Intel's Atom C2000 line could stop the board booting after about 18 months of use. Later boards were fixed, but check the revision on used units.
Does it have a PCIe slot for a GPU or RAID card?
No full-length PCIe x16 slot. Expansion is limited to a small slot and the on-board SATA and network ports.
