Socket AM3/AM3+ AMD 760G/780L micro-ATX board

The ASUS M5A78L-M LX is a micro-ATX motherboard built around the AMD 760G/780L chipset and Socket AM3/AM3+. It supports DDR3 memory up to 16 GB and includes one SATA cable, a CMOS battery and an I/O back panel. The board is sold new and suits upgrades or replacements for compatible AMD platforms.

Builders needing AM3/AM3+ DDR3 support

This board fits systems that require Socket AM3 or AM3+ processors and DDR3 memory in a micro-ATX form factor. Buyers who need a different CPU socket, a newer memory standard or a larger ATX layout should look at other options. The specification covers the essential compatibility points for this platform.

Maximum memory 16 GB DDR3

The single specification that decides fit is the 16 GB DDR3 memory ceiling. If the planned build requires more than 16 GB of system memory, this motherboard will not meet that requirement. Confirm the memory target before purchase to ensure compatibility.

Questions about this item

Does the Socket AM3/AM3+ interface limit memory to DDR3 and cap capacity at 16GB?

Yes. The board uses the AMD 760G/780L chipset with a Socket AM3/AM3+ CPU socket, which only supports DDR3 memory up to a maximum of 16GB.

What are the physical mounting requirements for this Micro ATX motherboard?

It follows the Micro ATX form factor, so it fits any case with Micro ATX or larger ATX mounting holes and a standard I/O shield cut-out.

How is the board installed, and which step is often missed?

Install the CPU and cooler, insert DDR3 modules, secure the board with standoffs, connect the 24-pin and 4-pin power cables, attach the supplied SATA cable and I/O shield, then fit the included CMOS battery — many builders forget the battery.
