Verdict

The ASUS TUF Gaming B660M-E D4 is a Micro-ATX motherboard built for 12th, 13th, and 14th Gen Intel processors on the LGA 1700 socket, featuring a robust 10-stage power solution and military-grade TUF components. Key specifications include support for up to 128GB of DDR4 memory at speeds up to 5333MHz (OC), two M.2 slots (both PCIe 4.0), and a PCIe 4.0 x16 expansion slot. Main pros include high-speed 2.5Gb Ethernet, a front-panel USB 3.2 Gen 2 Type-C port, and comprehensive cooling with enlarged VRM heatsinks. However, it lacks built-in Wi-Fi/Bluetooth (requiring a separate module) and uses the older Realtek ALC897 audio codec, which may offer less audio fidelity than higher-end boards.
