As of late 2023/early 2024, a good B650 ITX motherboard typically ranges from $180 to $300. Boards on the lower end ($180-$220) offer essential features but may compromise on VRM quality, connectivity, or cooling. Mid-range boards ($220-$260) provide a better balance of features and performance, with improved VRMs, more USB ports, and potentially Wi-Fi 6E.
Higher-priced boards ($260-$300+) justify the cost with premium VRM designs (for robust overclocking), enhanced cooling solutions, more M.2 slots, advanced features like integrated I/O shields, and potentially better audio codecs. Features like a front panel USB-C port, 2.5GbE LAN, and robust BIOS features also contribute to a higher price. Consider your specific needs and budget when evaluating the price-to-feature ratio.
Are B650 ITX motherboards suitable for overclocking Ryzen 7000 series CPUs?
While B650 ITX motherboards can be used for overclocking, they aren’t always the ideal choice compared to X670E. Overclocking success heavily depends on the VRM quality and cooling solution. Boards with robust VRMs (8+1+1 or higher phases, quality MOSFETs) and effective heatsinks are essential. However, the limited space in ITX cases can make maintaining optimal CPU temperatures challenging, potentially limiting overclocking headroom.
Data from overclocking communities shows that B650 boards can achieve respectable overclocks, often approaching the performance of X670E boards, but require more careful tuning and potentially more aggressive cooling. Expect to see diminishing returns with higher overclocks due to thermal constraints. If you prioritize extreme overclocking, X670E is generally a better option. For moderate overclocking and stable performance, a well-equipped B650 ITX board can be a viable choice.
