VRM Overview

Specifications

The ASRock X299 Taichi features a 13 phase VRM in a (6 x 2) + 1 configuration.


The Intersil ISL69147 PWM controller supports a maximum of seven phases in various configurations. In order to achieve 13 phases, ASRock uses six Intersil ISL6617A doublers located on the back of the board.


The ASRock X299 Taichi uses Intersil ISL99227B power stages for all 13 phases (12 for the Vcore and 1 for the SOC). These are just about top of the line when it comes to smart power stages, and ASRock has gone with the extra expense to maximize the Taichi's potential with power hungry HEDT CPUs.

The ASRock X299 Taichi has a maximum output of 720 A, which should handle even the monstrous i9-10980XE.
