ASUS M3N78 SE AM2/AM2+ Motherboard

The ASUS M3N78 SE is an ATX motherboard built for Socket AM2 and AM2+ processors. It supports DDR2 memory up to a maximum capacity of 8GB. This board suits users maintaining or repairing legacy AMD systems that require this specific socket and memory generation.

DDR2 Memory Up to 8GB

This board fits builders who need a replacement ATX board for an existing AM2 or AM2+ platform with DDR2 memory. It is not for buyers who want more storage interfaces than the provided SATA connections allow. It is also not for builders who need a second card slot configuration beyond what this specific layout provides.

Socket AM2 and AM2+ Compatibility

The CPU socket type is the single specification that decides whether this is the right part. The board accepts only Socket AM2 and AM2+ processors. Verify your processor matches one of these two socket types before purchasing.

Questions about this item

How much power does the M3N78 SE draw when it runs all day?

The board itself has no published TDP figure; total system draw depends on the AM2/AM2+ processor and DDR2 modules you install.

Which components must I already own for this motherboard to work?

You need a Socket AM2/AM2+ CPU, DDR2 memory up to 8 GB, a standard ATX power supply, and a case that fits an ATX board.

Will my existing SATA drives work with this motherboard?

Yes, the board provides SATA ports so current SATA hard drives or SSDs connect directly without adapters.
