Who it fits
Good fit for
This motherboard suits users building compact PCs who still want robust connectivity. The Micro-ATX size fits standard cases without taking up too much space. If you need Wi-Fi and Bluetooth built-in, the 802.11ac module saves you from buying a separate card. The dual M.2 slots and eight SATA ports offer plenty of storage options for media libraries or game collections. It is ideal for users who prefer DDR4 memory for cost savings while still wanting PCIe 4.0 speeds for their graphics card and primary drive.
Who should skip it
You should look elsewhere if you plan to use the latest DDR5 memory. This board only supports DDR4, which limits your upgrade path for future high-speed RAM modules. If you need more than two M.2 drives, you will run out of native slots quickly. Users seeking advanced overclocking features for extreme performance might find the 7-phase power design insufficient compared to higher-end Z-series boards. Additionally, the Wi-Fi standard is 802.11ac, which is slower than the newer Wi-Fi 6 or 6E standards found on more recent boards.
Verdict: The ASRock B660M-C is a practical, spec-rich board for compact Intel builds. It delivers essential connectivity and storage options without unnecessary complexity.
