Half the Asus boards have garbage VRM with four weak phases using very low end and only one high side FET.Has any VRM been proven to hold XFR back (with PBO disabled)?
VRM's tend to be overbuilt in my experience. Unless we talking extreme overclocking.
The Stilt found ROG Strix B450-F overheating its VRM after 12 minutes of x264 encoding with stock 2700X.
Some Prime etc load would likely overheat it even faster.
Also Gigabyte uses similar VRM design in B450 mobos running risks.
