The rather tidy-looking board does not hide any secrets. Power supply, input range, GPU and memory are located exactly where you would have expected them at first glance. GPU power supply is a normal 6+2 phase design, with single phases without a doubler for the GPU.
UPI Semiconductor's uP9022 directly controls the six Power-Stage chips. Asus relies on on the cheaper SiC620 from On Semiconductor, which are asymmetric Dual N-Channel MOSFETs with integrated Schottky diode that realize both the high and low-side.
The power supply of the memory is released via an uP1666 from uPI Semiconductor, which can provide the total of two phases as a buck controller. The control is taken over by a pair of one NVTFS4C06 and one NVTFS4C09 On Semiconductor per phase. The necessary gate drivers already contain the uP1666, so you don't need separate ICs. Positioning is above the GPU phases.
The back is largely free of larger active components except for some voltage converter MOSFETs for the peripherals and some SMD capacitors. The voltage converter range seems very tidy and one unfortunately wasted the chance to actively include the backplate in the cooling by means of a thermal pad.
