GIGABYTE Z790I AORUS Ultra
This board strikes an excellent balance of features, robust power delivery, and connectivity, making it a strong choice for a high-performance gaming Mini-ITX build with the i9-14900K. Its 10+1+2 phase digital VRM with 105A Smart Power Stages is well-suited for the CPU.
Platform Match
The Intel Core i9-14900K is a high-performance LGA1700 CPU, ideal for gaming and demanding workloads. It pairs best with Intel Z790 chipsets to unlock its full potential, including overclocking and robust connectivity.
VRM Guidance
For the i9-14900K's 125W TDP and overclocking headroom, a motherboard with a strong VRM and effective cooling is essential. Look for boards with robust power phases and substantial heatsinks to ensure stable power delivery and prevent thermal throttling in a Mini-ITX chassis.
Upgrade Path
Mini-ITX boards offer limited expansion, typically featuring one PCIe x16 slot and 2-3 M.2 slots. Prioritize DDR5 memory support, PCIe 5.0 for the primary GPU, and sufficient M.2 storage options for future upgrades.

Frequently Asked Questions
Can a B760 Mini-ITX motherboard handle an Intel Core i9-14900K?
Yes, a quality B760 Mini-ITX board with a robust VRM can run the i9-14900K, but Z790 is generally recommended for optimal performance and overclocking due to its superior power delivery.
What kind of CPU cooler is best for an i9-14900K in a Mini-ITX build?
Given the i9-14900K's heat output, a high-performance 240mm or 280mm All-in-One (AIO) liquid cooler is highly recommended for effective cooling in a compact Mini-ITX chassis. Air coolers may struggle.
Are there any specific considerations for RAM with these Mini-ITX boards?
Mini-ITX boards typically have only two DDR5 DIMM slots, limiting total capacity. Focus on high-speed DDR5 kits (6000MHz+) to maximize performance, as the 14900K benefits significantly from faster memory.
