VRM Overview

Cramming lots of power phases onto a Mini-ITX motherboard isn't easy and there's certainly fewer here than on other Socket AM5 boards we've seen recently. The vCore is equipped with 10 phases - two more than its predecessor and most B650 Mini-ITX boards for that matter - and it's a single phase each for the SOC and MISC. The temperatures were unsurprisingly a fair bit higher than average, peaking at 60°C after our 10-minute stress test with a Ryzen 9 9950X, but were in the process of levelling off and there were no signs of anything throttling.


We'd consider that a pass so as long as your system has reasonable airflow across the motherboard, it should be able to handle any current Ryzen CPU, at least at stock speed. For those wanting a little extra cooling, the rear of the PCB was the warmest area, so if you're concerned you could always add a slim fan to the other side of the CPU area cut out for a little extra cooling if there is space, and you're up for modding.


The single SOC stage is a 110 A using Renesas R2209004, Renesas RAA220075R0 for the MISC and R2209004 110 A again for the 10 vCore phases with RAA229621 and RAA229620 PWM controllers.
