With the heat sinks removed we can check out the VRMs and other ICs.
The motherboard is in a 4+3 phase VRM, and it uses zero doubling. It uses the Intersil ISL95866 PWM controller in 4+3 mode. It adds multiple ISL6625A on the CPU and iGPU rails to enhance phase count. The CPU VCore VRMs use double the number of MOSFETs per phase, while the iGPU phases use the standard number. On Semiconductor NTMFS4C06N is the low-side MOSFET, and the NTMFS4C10N is the high-side MOSFET for each of the power stages.
The memory VRM uses a Realtek RT8120D for a single phase PWM with driver and then three On Semiconductor NTMFS4C06N in a two-low one-high MOSFET configuration. More Realtek RT8120 controllers are used for the VCCSA and VCCIO rails.
