Verdict

The ASUS Prime Z390M-PLUS is a Micro-ATX motherboard built on the Intel Z390 chipset, supporting 8th and 9th Gen Intel Core processors via the LGA 1151 socket. Key technical features include four DDR4 DIMM slots supporting up to 128GB of memory at overclocked speeds of 4266+ MHz, dual M.2 slots with up to 32Gbps data transfer, and native USB 3.1 Gen 2 support. Its primary advantages are its robust power delivery for multi-core CPUs, comprehensive cooling controls via Fan Xpert 4, and durable 5X Protection III hardware safeguards. However, it lacks integrated Wi-Fi and Bluetooth connectivity, and its relatively basic Realtek ALC887 audio codec may not satisfy high-end audiophile requirements.
