The Z270 XPower Gaming Titanium hides a lot of interesting hardware under those heat sinks and shield.
The motherboard's VRM is in a 10+4 phase configuration for the CPU+iGPU. An International Rectifier IR35201 digital PWM is being used in 6+2 phase mode, and outputting 5+2 phases to doublers and then to IR3555A integrated power stages. The IR3555A are International Rectifier's second generation PowIRstages, and they are the top-dog rated at 60A. MSI is using the "Ti" branded high-current inductors, and many tantalum capacitors for the output filter. The VRM on the Z270 XPower is one of the most powerful I have seen on any Z270 motherboard.
The International Rectifier IR3599 is a phase doubler or quadroupler, and it's used as a phase doubler on this motherboard. The memory VRM uses a Primarion PV3205 digital PWM and some Nikos MOSFETs for a two-phase VRM, which is more than enough to power DDR4 DIMMs.
