The VRM on this motherboard is a 4+2 phase configuration for the CPU core and iGPU phases. The core phases and the iGPU phases use a dual low-side single high-side configuration. Each phase uses two Sinopower SM4336 and one SM4337 PowerPAKs. The PWM controller is the Intersil ISL95824 4+2 phase PWM controller with two integrated drivers for the main four phases and one for the iGPU rail. Two ISL6625A are used for the CPU core and one for the iGPU to supplement the internal drivers.

An Anpec APW8720 is a single phase PWM with an integrated driver, and it's routed to two sets of power stage components to create a giant single/dual phase VRM which uses Sinopower SM4337 for both the high-side and low-side MOSFETs.
