VRM Overview

The 18+1+2+2 phase power delivery is split into three areas, each cooled by a heatsink linked using a heatpipe. Temperatures climbed steadily for over 20 minutes before leveling off just below 70°C.


The enormous heatsink has a mid-mounted rather than direct-contact heatpipe, and the upper RGB lighting array will undoubtedly hurt it a little when it comes to thermals. However, the heatpipe should prevent the build up of hot spots, which is likely part of the reason for the tighter grouping of temperatures than usual.


We have a very similar power delivery arrangement to the more expensive ASUS ROG Crosshair X870E Dark Hero, just with fewer phases for vCore. We have 18 Infineon PMC41430 100 A stages for that, one 90 A Infineon PMC41420 stage for iGPU, plus a further two for VCCSA.


Lastly, we have two MPS2415 MPS87681 80 A stages for VNNAON, with Monolithic Power Systems also providing a PWM controller in the form of the tiny MPSS19 M2940C, which we've not seen since the MSI MPG Z890I Edge Ti Wi-Fi.


We also have a further pair of DIGI+ branded PWM controllers - the ASP2414 and ASP2414.
