Verdict

The ASUS Prime B660M-A D4 is a budget-friendly micro-ATX motherboard featuring the Intel LGA 1700 socket to support 12th, 13th, and 14th Gen processors. Key specifications include four DDR4 DIMM slots supporting up to 128GB at speeds up to 5333MHz (OC), dual PCIe 4.0 M.2 slots for high-speed storage, and a PCIe 4.0 x16 expansion slot for modern GPUs. Main characteristics and pros involve its surprisingly robust VRM design for its price point, comprehensive cooling with integrated M.2 and VRM heatsinks, and versatile connectivity including rear USB 3.2 Gen 2 ports and a front-panel USB-C connector. However, notable cons include the lack of built-in Wi-Fi or Bluetooth on this specific non-WIFI model and the absence of a rear-panel USB-C port.
