Verdict

The ASRock B660M Steel Legend is a micro-ATX motherboard designed for 12th, 13th, and 14th Gen Intel processors on the LGA1700 socket, featuring a robust 9-phase Dr.MOS power design and a 6-layer PCB for stable performance. Key technical specifications include support for up to 128GB of DDR4 memory at overclocked speeds of 5333+ MHz, a PCIe 5.0 x16 reinforced steel slot, dual Hyper M.2 PCIe Gen4x4 sockets, and Dragon 2.5G LAN. It offers excellent value with premium features like a front-panel USB 3.2 Gen2x2 Type-C (20 Gb/s) header, a BIOS Flashback button, and Polychrome RGB lighting, making it a strong choice for budget-conscious gamers and mainstream builds. However, notable drawbacks include the lack of built-in Wi-Fi (though an M.2 Key-E slot is provided), the use of an older Realtek ALC897 audio codec, and the absence of a high-speed USB Type-C port on the rear I/O panel.
