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.

Next up we have gigabyte. Typically not the best EFI however they have phenomenal Power Delivery and have wonderful OC abilities

Now we have ASUS. Great EFI not the best quality control as of late. A lot of features most of which you do not need and well they are damn sexy boards I will give them that.

Finally we have MSI. While some boards are good others are hit or miss. Particularly their mid tier. Nobody expects the low tier boards to perform anyways but the mid tier that slots into budget points the QA has been horrible for years. Quite frankly they have repeatedly tried to work on it but they are still havent figure it out. Im not quite sure why and I open to discussion about whats causing it. Their EFI looks amazing. They work close with AMD spec to provide the most tweakable options and they have decent looking boards…

What are VRMs?
Want to know more about power delivery check out this post: VRMs - The what, why and how they operate!
Why is this important with X570?
You might ask does power delivery matter if AMD Ryzen chips are so power efficient. It does primarily due to how ryzen boosts. Ryzen 3rd gen boosts very much like a GPU. If there is thermal and voltage headroom, The chip will boost. Idle is also much higher due to the characteristics of this particular node process. Do not be alarmed to see voltages higher than you expect. If you want to overclock these chips further then this is a pretty important fact to take into consideration.
The OMG its at 1.4+ Volts on board
This is normal. It should be expected at idle. As for spikes to 1.5 Volts, Ryzen 3000 has a very aggressive boost algorithm and all the kinks aren’t entirely worked out yet. Even minimal activity will cause boosting and therefore heat. 15+ degree spikes are entirely expected. 1.45ish+ VCORE is entirely normal for short bursts on single core workloads. This is because a higher voltage will drive down the temps from less current load. It is entirely safe. AMD has stated this themselves. ~1.38 is about max for all core loads. If you are concerned get on the latest AGESA provided by your board manufacturer.
So I hope this information helps some people. It kind of veered off topic for a bit.
