The ASUS ROG Crosshair X670E HERO features a 18+2+2 phase VRM configuration. These are setup in as "teamed" power stages, resulting in every two receiving the same PWM signal.


ASUS is using a DIGI+ ASP2205 PWM controller to drive the ASUS ROG Crosshair X670E HERO power stages.


The ASUS ROG Crosshair X670E HERO uses Vishay SiC850A power stages for the 18 Vcore phases. These power stages each support a maximum of 110 A of continuous current. For the SoC phase, ASUS is also using Vishay SiC850A (110 A) power stages (not pictured).


On one end of the VRM setup is the VDD_MISC power. This is using two Renesas ISL99390 (90 A) power stages and a Renesas RAA 229613 for the controller.

ASUS ROG Crosshair X670E HERO has a maximum output of 1,980 (A) dedicated to Vcore.
