Specifications

The ASRock X670E Taichi Carrara features a 24+2+1 phase VRM configuration, these are suspected to be configured as teamed phases, but a oscilloscope is required for confirmation.

Update: ASRock HQ can confirmed that the Vcore power stages are in a teamed configuration.

High-resolution version of the VRM is also available (FRONT).


ASRock is using a Renesas RAA229628 PWM controller to drive the X670E Taichi power stages.
