Platform Match
The Intel Core i5-12400 uses the LGA1700 socket, compatible with Intel 600 and 700-series chipsets. For a Mini-ITX build, B760 or H610 chipsets offer the best balance of size, features, and value.
VRM Guidance
With a modest 65W TDP, the i5-12400 does not require heavy VRM setups. Basic 5+1 or 6+1 phase power delivery is more than sufficient for sustained gaming workloads.
Upgrade Path
Mini-ITX boards limit expansion to one PCIe slot and two RAM slots. Choose DDR5 for future-proofing or DDR4 to minimize initial build costs.

Frequently Asked Questions
Can I use DDR4 RAM with these Mini-ITX motherboards?
Only if you choose a specific DDR4 board like the ASRock H610M-ITX/ac. Most modern B760 and Z790 Mini-ITX boards require newer DDR5 memory.
Does the Core i5-12400 require a Z790 motherboard for gaming?
No, the i5-12400 is locked and cannot overclock. A B760 or H610 motherboard is much more cost-effective while delivering identical gaming performance.
Will these Mini-ITX boards fit in a standard ATX case?
Yes, Mini-ITX motherboards use standard mounting holes and will fit in Micro-ATX and ATX cases, though they may look visually small.
