How to Choose the Best Mini ITX Motherboard
1. PC Case
Most mini ITX motherboards fit into a full-sized ATX cabinet, however that defeats the purpose of using a compact motherboard. Thus, you should be looking for mini-ITX or even micro-ATX cases for the best results. While a dedicated mini-ITX case is the best option for organizing space, a micro-ATX case will have added benefits like more room for cooling, additional fans and better cable management.
2. Memory support
Due to lack of space, most mini ITX motherboards have only 2 DIMM slots for RAM, and while some may go up to 64GB, many of them support only 32GB of memory. We have provided sufficient options for either category and we’ll leave up to you to decide which one you need depending on your requirements.
3. VRM and Cooling
The small form factor comes with real challenges when it comes to keeping it properly cooled, especially when overclocking. The more fan headers and heatsinks you can get, the better the performance will be. However, most mini-ITX boards are not recommended for extreme overclocking and you should seriously consider a full-sized board if that’s something you’re up to.
4. Other features
Most mini-ITX boards will only come with a single PCIe slot and do not support multi-graphics. Some of them have dual M.2 slots while others come with a single slot. Having additional features like Wi-Fi, RGB or USB-C ports should be decided based on personal preferences and budget.
We hope you are now ready to buy your new mini ITX motherboard. If you are planning to build a smaller PC setup and are looking for a solid motherboard to pair with your Ryzen CPU, any of the above options will be more than enough. Despite the smaller size, mini ITX PCs offer very competitive performance as compared to their ATX or micro-ATX counterparts. What’s even better is that they cost a lot less and are thus perfect for gaming in a limited amount of space.
