Designed for 10th Gen Intel Core

The ASUS ROG Maximus XII Formula uses an LGA 1200 socket paired with the Intel Z490 chipset. It accepts 10th Generation Intel Core, Pentium Gold and Celeron processors. Four 288-pin DDR4 slots support up to 128GB in dual-channel mode with speeds ranging from 2400 to 4700+(O.C.) MHz.

Sustained load power and cooling

Sixteen Infineon power stages rated at 70 amps each deliver stable voltage during extended heavy workloads. The CrossChill EK III VRM block combines extra-large heatsinks with a solid steel backplate, allowing both air and water cooling for the VRM, chipset and M.2 areas.

Installation notes

Standard ATX layout fits typical cases, but the integrated water block adds height near the CPU socket. The three M.2 slots share bandwidth with specific PCIe and SATA ports, so populating M.2_3 disables the third x16 slot and using M.2_2 in x4 mode disables SATA ports five and six. The two-inch LiveDash OLED and Aura Sync headers require internal USB and RGB connections.

Questions about this item

How loud and hot does the CrossChill EK III VRM block get when the 16 Infineon power stages run at 70 amps all day?

The hybrid cooling system combines the CrossChill EK III VRM block with extra-large heatsinks for the VRM, chipset and M.2 slots, plus a solid steel backplate that supports both air and water cooling to manage heat from the 16 power stages rated at 70 amps each.

Which DDR4 memory kit and 10th Gen Intel Core processor must I already own for this LGA 1200 board to post?

You need a 10th Gen Intel Core, Pentium Gold or Celeron processor for the LGA 1200 socket and DDR4 modules up to 128 GB across four 288-pin slots running at speeds from 2400 up to 4700+(O.C.) MHz in dual-channel mode.

Will my existing SATA SSDs and PCIe 3.0 add-in cards work alongside the three M.2 slots without losing bandwidth?

Six SATA 6Gb/s ports are available, though M.2_2 shares bandwidth with SATA ports 5 and 6 and runs x2 by default; the PCIe 3.0 x1 slot is disabled when M.2_1 operates in x4 mode, while M.2_3 shares bandwidth with the third PCIe 3.0 x16 slot.
