The CPU voltage regulator circuit of the ASRock Fatal1ty Z170 Gaming K6+ has 12+1 phases for the CPU. The voltage regulator uses an Intersil ISL95824 controller chip (digital design). Each phase uses two MOSFETs, but we were not able to identify the models.
The ASRock Fatal1ty Z170 Gaming K6+ uses high-end capacitors from the Japanese brand Nichikon (a.k.a. 12K Platinum capacitors) and all coils on this motherboard have 60 A specification.
