Now it's time to dig deep into the motherboard's circuitry.
The VRM on the Z270X-GAMING 7 is in an 8+3 phase configuration for the VCore and iGPU voltage rails. It seems that the VRM is a true 4+3 phase and the CPU VCore section is doubled to 8+3. The VRM on this motherboard should be adequate for overclocking the 7700K since it does not use all that much power.
The Intersil ISL95866 4+3 phase hybrid-digital PWM controller. Intersil uses something they call a Green hybrid digital R3 modulator, which they say provides the best of analog and digital PWM technology. It offers two integrated drivers for the CPU and one for the iGPU outputs, so GIGABYTE had to add two ISL6625A drivers for the iGPU and two more for the CPU to get 4+3 phases, which they then doubled on the CPU side to 8+3 by doubling the number of MOSFETs on each driver.
The MOSFETs are the same Vishay SiRA12 for the low-side and SiRA18 for the high-side that GIGABYTE used on the Z170X-Gaming 7. The memory VRM receives the same MOSFETs, but uses a two low and single high configuration and a Richtek RT8120 single phase PWMN with integrated driver.
USB DAC-UP 2 offers power control and voltage compensation for select USB 3.0 ports/headers. The two internal headers each get their own dedicated voltage regulator circuit that utilizes a Richtek RT8288A 4A step-down converter.
