VRM Overview

Specifications

The ASUS Prime X570-Pro features a 6 phase VRM in a simple 4 + 2 configuration. No doublers are used.


The ASP1106 controller supports a maximum of four Vcore phases and two SOC phases. In order to handle the current requirements of the latest Ryzen 3000 processors, ASUS has installed three power stages for each Vcore phase.


The ASUS Prime X570-Pro uses the SiC634 from Vishay across the board. These 50 A power stages give ASUS a total of 150 A per Vcore phase. While the result is far less sophisticated than a true 14 phase, the power output is there.

The ASUS Prime X570-Pro has a maximum output of 600 A, and while we won't know for sure until the Ryzen 3950X launches, this should be more than sufficient even for LN2 overclocking.
