The main CPU VRM is cooled by a large one piece heat sink also connected to the PCH and PLX bridge chip. It cools down the CPU VCore and iGPU phases. In total, there are eight CPU phases and four iGPU phases. Each phase gets a single EVGA custom branded inductor, and the output capacitor bank is a mix of 5K solid polymers, POSCAP tantalums, and some MLCCs. Two IR PWMs control the CPU VCore, iGPU, and VCCSA.

EVGA is using two International Rectifier IR35201 digital PWMs that can operate in 6+2 phase mode or 8+0 phase mode. All the CPU VCore, iGPU, and VCCSA phases use International Rectifier IR3553 PowIRstages which are 40A integrated power stages. It looks like EVGA is utilizing 4 phases of one PWM to directly power the four iGPU phases. The other PWM looks like it is providing 4 phases to four IR3599 phase doublers (located on the back of the motherboard) which then output to make 8 CPU VCore phases. The extra PWM rail of one of the PWMs is controlling the IR3553 that powers the VCCSA.

The memory is utilizing two IR3553 for the main DDR voltage and a single IR3553 for the DDR-VPP rail. An International Rectifier IR3570 (3+2 phase digital PWM) is used to control the DRAM power. A single IR3553 used for the VCCSA is located right next to an International Rectifier IR3898 SupIRbuck, which is a 6A integrated single phase VRM.
