The VRM is in a 12+1 phase mode for the VCore/Input voltage and VCCSA. The inductors are rated 65A, and the capacitors are rated 12K. There are three Intersil ISL69138 fully-digital PWMs, which offer two rails in X+Y=max 7 phases. In this case, it's being used in a 6+1 phase mode.

The new PWM is paired with the ISL99227B 60A Smart Power Stages and offers internal current and temperature sensing, which allows them to operate at high-efficiency levels since they have quick and accurate internal feedback loops. Six Intersil ISL6617 phase doublers are located on the back of the motherboard and double 6 PWM phases to 12 for the CPU core power rail.

Each memory VRM uses two Fairchild FDPC5030SG, and the VCCIO uses one. They are high current dual N-Channel MOSFETs that integrate both the high and low-side MOSFETs. Each set of 8 DIMMs gets two phases for main DDR4 power, and the phases are controlled by underutilized ISL59138 PWMs.
