Our take on the Supermicro A1SAI-2750F-O | Intel Atom C2750/ DDR3/ SATA3/USB3.0/ V/4GbE/ Mini-ITX System Board (Motherboard) / CPU Combo

The A1SAI-2750F-O is a mini-ITX board with an Intel Atom C2750 soldered on: eight Silvermont cores at 2.4 GHz, 20W TDP, no fan needed. It carries four Gigabit Ethernet ports, six SATA3 headers, two USB 3.0 ports and a single DDR3 SO-DIMM slot, all in a 6.7-inch square. It suits a quiet home router, firewall or NAS build rather than a general-purpose PC. Against newer Atom C3000 and Xeon D boards it is older and capped at 32GB of RAM, but the four NICs and low power draw remain its draw for network appliances.

What reviewers say

  • 4.6 / 5149 ratings

Owners rate it highly as a stable, low-power network board. Most praise the four NICs and fanless operation; complaints center on the single memory slot and the dated Atom performance.

What people mention
  • Network portsPraisedOwners like having four Gigabit NICs onboard for router and firewall builds.
  • CoolingPraisedThe 20W chip runs passively cooled and stays quiet.
  • MemoryCriticisedA single SO-DIMM slot and DDR3 cap memory at 32GB.
  • PerformanceMixedFine for routing and light serving, but weak for transcoding or heavy compute.
  • StabilityPraisedLong uptime with no crashes reported by owners.

Questions and answers

Is this board good for pfSense or OPNsense?
Yes. Four onboard Gigabit ports and a fanless 20W CPU make it a common choice for a quiet firewall. It handles routing and VPN traffic well at home or small-office scale.
How much RAM can it take?
One DDR3 SO-DIMM slot, up to 32GB in supported modules. Check Supermicro's validated memory list before buying, since not every SO-DIMM works.
Does it support hardware transcoding?
No. The Atom C2750 has no Quick Sync, so Plex and Jellyfin transcoding falls to the CPU and is slow. Use direct play or add a GPU elsewhere.
What is the difference from the non-F version?
The -F suffix adds IPMI remote management, so you can control the board headless over the network. The base version lacks it.
What comes in the box?
The board with the Atom C2750 soldered on, plus I/O shield and SATA cables. CPU, cooler and memory are not separate purchases; RAM and storage are not included.
Is it worth it over a newer Atom C3000 board?
Pick this for the four NICs and low cost if routing is the job. A C3000 or Xeon D board gives more memory headroom and newer I/O for heavier workloads.
