LGA 1851 platform for Intel Core Ultra Series 2

This motherboard targets enthusiasts building high-end workstations or gaming rigs around Intel Core Ultra processors. The Z890 chipset unlocks overclocking headroom for both CPU and memory. Four DDR5 slots support up to 256 GB total capacity with XMP 3.0 profiles.

EZ-Latch hardware simplifies storage and GPU swaps

Tool-free M.2 EZ-Latch clips secure up to four SSDs without screws while PCIe EZ-Latch releases graphics cards with one finger. Dual Thunderbolt 4 ports add 40 Gbps external bandwidth for docks or storage arrays. Front-panel USB-C header connects modern cases directly.

PCIe 5.0 lane allocation shapes expansion choices

The CPU provides one x16 slot at PCIe 5.0 and one M.2 at PCIe 5.0 x4; a second CPU-attached M.2 runs at PCIe 4.0 x4. Two chipset M.2 slots and a PCIe 4.0 x4 slot share downstream bandwidth. Four SATA 6 Gbps ports and dual 10 GbE LAN complete the I/O map.

Questions about this item

Will the 20+1+2 phase VRM with 110A power stages need active cooling or replacement under long-term heavy loads?

The VRM Thermal Armor Advanced heatsink covers the 20+1+2 phase design with 110A smart power stages and is built for sustained operation without scheduled replacement.

Which thermal limit appears first when all four M.2 slots run PCIe 5.0 or 4.0 drives continuously?

M.2 Thermal Guard heatsinks cover the CPU and chipset M.2 connectors to manage drive temperatures during sustained PCIe 5.0 and 4.0 workloads.

How loud are the chipset and VRM fans when the board runs 10GbE LAN, Wi-Fi 7 and Thunderbolt 4 all day?

The board uses passive VRM Thermal Armor Advanced and M.2 Thermal Guard cooling with no chipset fan, so sustained 10GbE, Wi-Fi 7 and Thunderbolt 4 traffic adds no fan noise.
