Socket AM3 motherboard with AMD 785G

The ASUS M4A785-M is a Micro ATX board built around the AMD 785G chipset and a Socket AM3 CPU interface. It supports up to 16 GB of DDR2 memory for systems that still rely on that standard. The form factor fits compact chassis while keeping essential connectivity.

Bundled accessories for basic assembly

The package adds a CMOS battery, one SATA cable and a chassis I/O back panel so the board can be installed straight into a case. A Wi-Fi antenna is also supplied if the specific unit includes an on-board wireless module. No other cables, brackets or software discs are provided.

Suited for legacy DDR2 builds only

This board matches users replacing a failed motherboard in an existing AM3 or AM2+ system that already uses DDR2 modules. Anyone starting a new build or needing modern memory types, additional expansion slots or current-generation chipsets should select a different platform.

Questions about this item

Will the CMOS battery need replacing on the ASUS M4A785-M?

A CMOS battery is included with the board; it will need replacement when the system clock or BIOS settings stop holding after power loss.

What limits the AMD 785G chipset under sustained load?

The integrated graphics share system DDR2 memory, so bandwidth and capacity become the first bottleneck during extended graphical workloads.

How much heat or noise does the ASUS M4A785-M produce running all day?

The Micro ATX board uses passive cooling on the 785G chipset, so it runs silently; total heat output depends on the installed CPU and case airflow.
