VRM Overview

Despite the large heatsinks and heat pipe, the VRMs weren't the coolest we've seen, but did stay well under 80°C and only topped 70°C after 15 minutes at full load with our Ryzen 9 9950X. If you have decent airflow over the VRMs or are mostly gaming or using a less powerful CPU, you'll see much lower temperatures, and while it's a tad warm, it's far from a fail.


The heatsinks that cool the 14+2+2 power delivery are relatively large considering the price tag, but focus mainly on maximizing surface area rather than volume, so our worst case scenario stress test with minimal airflow is perhaps not showing them in their best light. Still, we have seen cooler from similarly-priced boards.


There are two PWM controllers on the top side of the PCB with a 2-phase Richtek RT3672EE dealing with the two MISC phases and Richtek RT3678BE for the rest, just like the Gigabyte B850 Eagle WiFi7 Ice.


We have OnSemi Semiconductor 4C10N MOSFETs for MISC, while the 14 vCore and two SOC stages are OnSemi NCP 302155R 60 A stages, again similar to the Gigabyte B850 Eagle WiFi7 Ice, which also had rather high VRM thermals.
