Socket and chipset

The ASUS PRIME B365M-A is a Micro ATX motherboard built around the Intel B365 chipset and the LGA 1151 socket. It accepts 8th and 9th generation Intel Core processors and targets builders who need a compact, cost-conscious platform for everyday computing or light productivity.

Memory capacity and limits

Four DDR4 slots support up to 64GB of system memory, giving ample headroom for multitasking, office suites and mainstream content creation. The board reaches its limit at that ceiling, so workloads requiring larger datasets or heavy virtualisation will need a different platform.

Thermals and power behaviour

The B365 chipset runs cool under typical desktop loads, allowing passive cooling to keep noise low in a standard chassis. Power draw stays modest with mainstream CPUs, so a regular ATX supply handles the board, a SATA drive and usual peripherals without strain.

Questions about this item

Will the LGA 1151 socket on this B365 board accept the 8th- or 9th-generation Intel CPU I already own?

The socket is LGA 1151, which is the physical interface used by those processor generations; confirm your specific model against the board's supported CPU list before installing.

How can I verify the DDR4 memory is running at the correct capacity after I install it?

Enter the UEFI BIOS on first boot — the main screen reports total detected memory; it should show the full amount you installed up to 64 GB.

The listing says the box contains only the board, one SATA cable and the I/O shield — do I need to buy a CMOS battery separately?

A metal battery is included, so no separate CMOS cell is required; you will still need to source a CPU cooler, DDR4 modules, storage drives and a Micro-ATX compatible case.
