Verdict

The ASRock B660 Pro RS is an ATX motherboard designed for 12th, 13th, and 14th Gen Intel Core processors on the LGA1700 socket, featuring a reliable 8-phase power design and four DDR4 DIMM slots supporting speeds up to 5333MHz (OC). Key specifications include one PCIe 4.0 x16 steel-reinforced slot, two Hyper M.2 slots (PCIe Gen4x4), and an additional M.2 slot for WiFi modules. Its primary pros include an attractive price point for a full-sized board, stable Intel Gigabit LAN, and versatile connectivity with a front-panel USB 3.2 Gen1 Type-C header. However, notable cons include the lack of built-in WiFi, a maximum rear USB speed of only 5Gbps (USB 3.2 Gen1), and thermal performance that can struggle under high-power loads when paired with top-tier i9 processors.
