We see the VRM here is in a 10+2 phase mode and uses an ASP1405I PWM which is most likely an IR35201. It's in 5+2 phase mode doubled to 10+2 through five IR3599 doublers on the back of the motherboard.

Each phase for the VCore and SoC uses an IR3555M 60A PowIRstage, and a Micro-Fine Alloy choke. ASUS did something interesting this time; they positioned the two SoC phases in between VCore phases to break up thermals a bit since the SoC phases are loaded a lot less. The top six phases are VCore, and the bottom four in the "L" (if the motherboard is upright) are VCore. The memory VRM is in a 2-phase configuration and uses a Digi+ ASP1103 PWM with integrated drivers and some ON Semiconductor mini MOSFETs.
