Verdict

The Asus EX-B660M-V5 D4 is a Micro-ATX motherboard featuring the Intel B660 chipset and LGA 1700 socket, supporting 12th, 13th, and 14th Gen Intel Core processors. Built for durability, it includes an 8-pin ProCool connector, luminous anti-moisture coating, and 5X Protection III. Key specs include two DDR4 DIMM slots supporting up to 64GB at 5333MHz (OC), one PCIe 4.0 x16 slot, and two M.2 slots (both supporting PCIe 4.0 x4). Its main pros are the robust protection features like USBGuard and LANGuard, making it ideal for iCafés or long-term gaming, alongside 4K@60Hz HDMI 2.1 support. However, its primary cons are the limited expansion with only two RAM slots and a lack of integrated Wi-Fi or Bluetooth.
