The X370 Krait Gaming looks good in the nude.
The VRM is in an 8+2 phase configuration. The PWM controller is the Richtek RT8894A offers 4+2 phase operation, with three integrated drivers on the 4 phase channel. Richtek is using the PWM in 4+1 phase mode and doubling the phases by doubling the number of components on each driver. The three integrated drivers are supplemented by one RT9624F for the main four CPU phases. Another RT9624A is used for the SOC phase.
High and low-side MOSFETs are Nikos PK616BA and PK632BA PowerPAK MOSFETs. The memory VRM is controlled by a Richtek RT8125E single-phase PWM controller with integrated driver. The memory VRM uses double the number of MOSFETs for the single phase, and should be enough for four DDR4 DIMMs.
