Micro ATX AM4 board for DDR4 builds

The ASUS PRIME B450M-A is a Socket AM4 motherboard built around the AMD B450 chipset for compact DDR4 systems. It fits Micro ATX cases and supports up to 128GB of memory across four slots. The board targets builders who want a standard AM4 foundation without a full-size ATX footprint.

Rear I/O shield and single SATA cable in the box

A chassis I/O back panel is included so the rear ports align cleanly with the case cut-out. One SATA cable ships with the board for a first drive connection; additional cables are sourced separately. The package also supplies a fresh CMOS battery, and the description notes a Wi-Fi antenna only when the specific model variant includes an onboard Wi-Fi module.

Standard B450 thermals

The B450 chipset and AM4 voltage regulators run at typical desktop temperatures under ordinary workloads. No active chipset fan is present, so system airflow handles the heat. Power draw stays within normal AM4 platform limits for the supported processors.
