Platform Match
The Intel Core Ultra 9 285K requires the LGA1851 socket, supported by Intel 800-series chipsets like Z890 or B860. This platform transitions exclusively to DDR5 memory and PCIe 5.0 connectivity.
VRM Guidance
The Core Ultra 9 285K demands robust power delivery due to its high power draw. Mini-ITX boards require premium VRMs with active cooling or heavy heatsinks to prevent thermal throttling.
Upgrade Path
Mini-ITX builds are limited to two DDR5 DIMM slots and typically two M.2 slots. Ensure your chosen board supports PCIe 5.0 for future GPU upgrades.

Frequently Asked Questions
Can I use my older LGA1700 CPU cooler on the LGA1851 socket?
Yes, LGA1851 shares the same mounting hole spacing and Z-height as LGA1700, making most LGA1700 coolers fully compatible.
Is a Z890 motherboard required for the Core Ultra 9 285K?
No, but Z890 is highly recommended to enable CPU overclocking and ensure the robust VRMs needed to sustain the 285K's high power demands.
Do these Mini-ITX boards support DDR4 memory?
No, the LGA1851 platform and all Z890/B860 motherboards exclusively support DDR5 memory.
