The Z270GT6 shows off its hardware when the heat sinks come off.
The motherboard's VRM is in a 6+2 phase configuration for the CPU+iGPU. The main PWM, an Intersil ISL95866 offers 4+3 phase output, but only 3+2 are being used. The PWM has two integrated drivers for the first rail and one for the second, so BIOSTAR supplements those with ISL6625A drivers.
The MOSFETs are Sinopower SM4364 and SM4377 for the high-side and low-side MOSFETs. Doubling from three to six phases for the CPU is done by doubling the number of power stage components on each driver.
The memory VRM uses an Anpec APW7120 single-phase PWM controller with integrated driver, and the power stages are the same SM4377 we saw used in the CPU VRM.
