## Long description

The ASUS PRIME B550M-K ARGB is a micro ATX motherboard based on the AMD B550 chipset with Socket AM4, designed for desktop PC builds that require stable power delivery, flexible cooling and modern storage options. It supports up to 64 GB of DDR4 memory across two slots, includes two M.2 connectors (one supporting PCIe 4.0 speeds up to 64 Gbps), and provides Gigabit Ethernet connectivity and standard PCIe expansion in a compact form factor.
Advantages
The board offers a robust power design and comprehensive thermal controls configurable via Fan Xpert 2+ software or the UEFI BIOS. An integrated Energy Processing Unit (EPU) helps optimize system-wide power consumption and enable power-saving Away mode. Dual M.2 slots allow fast OS and application drives, while audio shielding, dedicated PCB audio layers and premium capacitors improve onboard sound quality. Hybrid fan headers and multiple temperature-sensor inputs enable tuned cooling for both CPU- and GPU-intensive tasks.
Suitable for
Home and office desktop builds with Socket AM4 processors
Compact micro ATX systems requiring up to 64 GB DDR4 memory
Systems needing NVMe M.2 storage with one PCIe 4.0-capable slot
Users who want configurable fan control and energy-saving features
