Hey guys I just wanted to give everyone the VRM types and motherboard power delivery specs for the major players. Often people like to know these kinds of things Ive compiled a list if them together from various sources. It should help in any decisions… for OC boards and what not. However to be honest there are many reasons to have good power delivery.
I for one wish these were more public. Its a darn shame that people who work for the manufacturers or even the hacks who O.C do not share this information and when you ask most do not share as if its some kind of secret. Perhaps it is and I am not in the know but here are all the ones I know and Im sharing it with all… I appreciate the crowdsourcing of errors and confirming the unknown or blank spots…
Let us start with the better quality boards and companies and go in descending order. I am determining quality based on the last 3-4 years of QA, the quality of UEFI, the quality of UEFI updates and supporting new chips, and the quality of the features and power delivery onboard. Right before we start I will list the power stages companies and what the model numbers say.
List of Companies
IR= Infineon Technologies
ASP= Proprietized ASUS customized version of IR35201
uPI= uPI Semiconductor
TDA= Infineon Technologies
QA= Offshoot of uPI
SIC= Vishay Semiconductor
S4= OnSemiconductor
ISL=Intersil
Let’s begin with ASrock the best company as of late.

Take a look at this post for info
Also someone on LTT did a comparison for x570
I strongly recommend x470 or B450 for the reasons I described above, but if you want a x570 board check out the tier lists to see if you’re getting a good board or not
