The Z370 AORUS Gaming 5 reveals its secrets when the heat sinks and shields come off.

The phases we see here are split into an 8+3 phase configuration for the CPU VCore and the iGPU voltage rail. We get four phases doubled to eight through doubling the number of VRM power stage components on each driver output, and we get three true phases for the iGPU from the PWM controller. We are not certain on the ratings on the capacitors or inductors, other than the capacitors are solid polymer capacitors.

The VRM on this motherboard uses Intersil's ISL95866 4+3 phase PWM controller. It offers four phases for the CPU VCore, and on that rail, it has two integrated driver outputs and GIGABYTE adds two more drivers (ISL6625A) for a total of four driver outputs. These four driver outputs goto two sets of power stage components. The On Semiconductor NTMFS4C06N is the low-side MOSFET, and the NTMFS4C10N is the high-side MOSFET for each of the power stages. Each power stages get ones high-side and one low-side MOSFET if we consider each power stage and individual phase by inductor count. The VCCSA and VCCIO get their power from their one single phase VRMs. Each uses a Richtek RT8120D (single phase PWM with integrated driver) and two ON Semiconductor MOSFETs.

The memory VRM uses a Richtek RT8120 single phase PWM with integrated driver and powers a two-low-side MOSFET and single high-side MOSFET power stage made up of On Semiconductor NTMFS4C06N MOSFETs. On the rear IO panel, we have two DAC-UP 2 ports, and these are powered by their own regulator, the Richtek RT8288A, which gives the user control over the power to the two yellow USB ports.
