Now it's time to dig deep into the motherboard's circuitry.
The Z270X-Gaming 9 hides a lot of expensive circuitry below the heat sinks and plastic shields. Let's see what it's hiding.
Starting from the bottom right of the VRM chokes, the first four phases are 4 phases directly wired to an IR PWM controller. Next are 16 phases, which are derived from 8 true phases doubled by eight IR3599 phase doublers. Following them are three other phases for the VCCIO and VCCSA, and a remaining single phase to power the PEX8747. GIGABYTE is using two IR35201 digital PWM controllers from International Rectifier. The PWM can work in 8+0 mode as it is for the CPU VCore rail or in a 6+2 or 7+1 mode as it is for the iGPU and VCCSA segments of the VRM.
Each phase uses an International Rectifier IR3553 40A integrated power stage. The IR3553 integrate the high-side, low-side, and driver into a single package. The IR3599 is being used as a doubler to double eight PWM phases to 16 for the VCore, but they can also be used as a quadroupler, but they aren't being used in that mode here.
The memory VRM utilizes an International Rectifier IR3570 3+2 phase PWM to power a two-phase VRM for the main DDR4 voltage rail and a single phase for the DDR4 VPP rail.
Looking closer at the area around the two USB 3.0 internal headers reveals two discrete USB power regulators, used to add a slight voltage boost or total severe power for USB based DACs. The technology behind the power for the USB headers is called USB DAC-UP 2.
