The CPU voltage regulator circuit of the Gigabyte Z170X-Gaming 7 has 11 phases for the CPU. The voltage regulator uses an Intersil ISL95856 controller chip (digital design). Each phase uses two MOSFETs, but we were not able to identify the models.
The Gigabyte Z170X-Gaming 7 uses high-end “black” solid capacitors (a.k.a. 10K capacitors) and all coils on this motherboard are ferrite ones.
