MSI X670E ACE Motherboard Review

VRM Overview

VRM-wise, the ACE comes out swinging with a 22+2+1 phase design, so 22 for the VCore, 2 for SOC power and 1 for miscellaneous power, generally for IO and other devices.

The Vcore phases are rated at 90 Amps each and are controlled by the Infineon XDPE192C3B digital PWM controller and MSI have opted for a Duet rail system meaning that the power phases are doubled with a maximum continuous current of 1980 Amps on the Vcore, while the SOC phases are rated at 70 Amps each.

To keep all of that power at bay, in terms of cooling, MSI has gone quite big on the VRM heatsinks comprising of a direct touch heatpipe design that spans all of the phases and connects through to a stacked fin array heatsink.

On the other side of the PCB, MSI has installed a MOSFET baseplate to assist in transferring heat away from the phases, as well as having that large backplate that spans the rear of the board to assist in cooling too.
