Which CPUs fit this board?

It takes AM3 socket processors. Check the CPU support list for the exact board revision before buying a chip, since not every AM3 model is guaranteed to post.

How much memory can I install?

Up to 16GB of DDR3 across the memory slots. DDR3 is no longer used in new builds, so buy matched modules from the used market.

Can I run it without a graphics card?

Yes. It has VGA and digital display outputs, so a CPU with integrated graphics can drive a monitor directly.

Does it support an M.2 SSD?

No. Storage goes through SATA ports, so plan on a 2.5-inch SSD or a hard drive.

What comes in the box?

The A78SD3 motherboard only. Cables, a backplate and a manual are not listed, so check what you need before assembly.

Is it worth it over a newer AM4 board?

Only if you already own an AM3 CPU and DDR3 memory. For a new build, an AM4 board gives you DDR4, M.2 and current processors.

Our take on the Reliable Component AM3 Circuit Board

The A78SD3 is a compact micro-ATX motherboard for AMD AM3 processors, built around DDR3 memory and solid capacitors. It carries VGA and digital display outputs, so it can run without a graphics card, and it offers PCIe expansion slots for a GPU or sound card. It suits a budget rebuild, a spare desktop or a home office machine using parts you already own. Against newer AM4 boards it is dated: no DDR4, no USB-C, no M.2, and AM3 chips are long out of production.
