Description
The ASUS PRIME B660M-A WIFI D4 Micro-ATX motherboard is designed for assembling a compact, versatile PC for work, study, and entertainment. Based on the Intel B660 chipset, the model supports Intel processors with Alder Lake and Raptor Lake cores. The CPU installs into an LGA 1700 socket. The device features 3 PCI-E x16 slots. Multi-GPU configurations are not supported.
The ASUS PRIME B660M-A WIFI D4 motherboard is compatible with DDR4 RAM, with a maximum capacity of 128 GB sufficient for any typical home or office tasks. Intel XMP memory overclocking technology is supported. Memory acceleration is primarily beneficial in games.
The board's audio adapter supports 7.1 surround sound. 2 M.2 slots are used for high-speed NVMe solid-state drives. An advantage of the model is the presence of Wi-Fi and Bluetooth modules, enabling wireless connections without additional hardware. Wired connection to the local network and the Internet is provided at speeds up to 1 Gbps. Passive cooling on one of the M.2 slots, the chipset, and the VRM area protects the board from overheating.
