ASUS ROG Strix Z790-I Gaming WiFi
This board is an elite choice for the 14900KS, offering a powerful VRM and premium features in a compact ITX design. Its unique ROG Strix Hive external module enhances connectivity and audio, making it ideal for high-end gaming builds.
Platform Match
The Intel Core i9-14900KS is a high-performance LGA1700 CPU, demanding a robust Z790 chipset motherboard for optimal gaming performance and overclocking capabilities. Mini-ITX form factor requires careful component selection to manage thermals effectively.
VRM Guidance
With the i9-14900KS's peak power draw exceeding 400W under load, a motherboard with a strong VRM (10+ phase, 105A power stages) and excellent cooling is critical for stability and sustained performance, especially in a compact Mini-ITX build.
Upgrade Path
Prioritize DDR5 memory for maximum performance. Ensure adequate M.2 slots for high-speed storage, with at least one PCIe 5.0 M.2 slot if future-proofing is a concern. PCIe 5.0 x16 for the GPU is standard.

Frequently Asked Questions
Is a B760 Mini-ITX motherboard suitable for the Intel Core i9-14900KS?
While a B760 board may technically support the 14900KS, it lacks CPU overclocking features and typically has weaker VRMs, which are insufficient for sustained peak performance of this power-hungry CPU.
What kind of CPU cooler is recommended for the i9-14900KS in a Mini-ITX build?
Due to the 14900KS's high heat output (often reaching 100°C), a high-performance 360mm AIO liquid cooler is strongly recommended, even in a Mini-ITX chassis, to prevent thermal throttling.
Will a PCIe 5.0 M.2 SSD impact GPU performance on these Mini-ITX boards?
On some Z790 ITX boards, using a PCIe 5.0 M.2 SSD might share bandwidth with the PCIe 5.0 x16 GPU slot, potentially reducing the GPU to x8. Check specific board manuals for details.
