The Maximus IX Apex looks good in the nude!

The VRM on this motherboard is in an 8+2 phase configuration. Each phase uses a Texas Instruments CSD87350 NexFET, which offer a smaller footprint, high efficiency, and solid output current. The motherboard's PWM is from IR/Infineon and is labeled ASP1405. The ASM1405 seems to be the IR35201(6+2) or IR35203(4+2 phase), but it doesn't matter exactly which one since the PWM outputs 4+2 phases. There are multiple IR3599 phase doublers used to double four PWM channels to eight for the CPU VCore. ASUS has also chosen to use their Micro Fine Alloy chokes, and 10K gun-metal Japanese FP caps.

On the backside of the motherboard, we find 10 IR3535 drivers, one per phase. Skylake and KabyLake don't use much power, and four phases are enough, ASUS is also doubling the correct way. For the VCCIO, VCCSA, and other minor CPU rails ASUS uses a combination of Texas Instruments fully-integrated power converters and single phase VRMs. We also can find an IDT6V41638 clock buffer to improve BCLK clocking abilities.

The memory VRM consists of two phases using one high-side MOSFET and one low-side MOSFET; their form factor is very small to offer more space for overclocking features. The PWM for the memory VRM is the ASP1103.
