VRM Overview

Specifications

The ASUS ROG Maximus XII Extreme features an 8-phase VRM configuration using a parallel, or "Teamed," power-stage design. Two Infineon TDA21490 power stages run in parallel for each phase, which gives ASUS double the power-handling capability without using any doublers.


ASUS is using one of their own Digi+ VRM ASP1405I PWM controllers to drive the ROG Maximus XII Extreme. A second Digi+ VRM ASP1405I is set up underneath the socket to handle the VCCSA power delivery, which is also clustered between the socket and first PCIe slot.


The ASUS ROG Maximus XII Extreme uses Infineon TDA21490 power stages for all eight phases. With no iGPU support, all 16 stages are dedicated to Vcore. These power stages each support a maximum of 90 A of continuous current. When paired with the chunky VRM cooling solution, the ROG Maximus XII Extreme should be a capable overclocker.

The ASUS Z490 PG ROG Maximus XII Extreme has a maximum output of 1440 A.
