Verdict

The ASUS TUF Gaming B660M-Plus D4 is a Micro-ATX motherboard designed for 12th, 13th, and 14th Gen Intel processors on the LGA 1700 socket, featuring a robust 10+1 DrMOS power stage and 5333 MHz (OC) DDR4 memory support. It is equipped with advanced connectivity including a PCIe 5.0 x16 slot, two PCIe 4.0 M.2 slots with flexible heatsinks, Realtek 2.5Gb Ethernet, and a high-speed rear USB 3.2 Gen 2x2 Type-C port (20 Gbps). Key pros include military-grade durability, excellent power delivery for its class, and Thunderbolt 4 header support, though it lacks built-in Wi-Fi and Bluetooth (standard on the 'WIFI' version) and features a dated Realtek ALC897 audio codec.
