Verdict

The ASUS ROG Strix B660-I Gaming WiFi is a feature-rich mini-ITX motherboard built on the Intel B660 chipset, supporting 12th, 13th, and 14th Gen Core processors via the LGA 1700 socket. Key specifications include support for up to 64GB of DDR5 memory (6200+ MHz OC), a PCIe 5.0 x16 slot for modern GPUs, and two PCIe 4.0 M.2 slots for high-speed storage. It is equipped with an 8+1 power stage VRM design, Intel 2.5 Gb Ethernet, and onboard WiFi 6 with Bluetooth 5.2 for robust connectivity. Notable pros include its premium SupremeFX S1220A audio codec with a Savitech amplifier, DIY-friendly features like the M.2 Q-Latch and pre-mounted I/O shield, and solid thermal management for its compact size. However, main cons include the lack of CPU overclocking support (chipset limitation), a relatively high price point for a B660 board, and potential thermal throttling under extreme stress tests with high-end CPUs.
