What Is VRM?
VRM stands for voltage regulator module. It is a buck converter that provides a microprocessor the appropriate supply voltage, converting +5 V or +12 V to a much lower voltage required by the CPU.
VRMs are especially important for overclocking a CPU or GPU.
Many People Confused About Which Motherboard they should choose for their respectable CPUs.
Here is a Chart/Tier list of all the possible Motherboards.

There’s a few things to note/explain about the list:
Every current draw bracket has some CPUs at the top of the column to indicate what CPU under what scenario fits there . So for example the 150A category is appropriate for highly OC’d 3900X’s.
These current draw figures are for very high current draw scenarios, like with P95 AVX or IBT running. The [OC] tag represents a very aggressive ambient OC, like 4.2GHz at 1.38V for a 2700X. The [Stock] placements I’m a bit more uncertain about, particularly with the 3950X, that could be closer to somewhere in between 150A and 100A.
For phase count, something like 6 * 2 indicates a 6 phase design using doublers, and also there’s no differentiation for “big” phases. which have more components per phase. Instead the mosfet count per phase is just increased.
If the rating is “not recommended” that doesn’t mean it won’t work. I just don’t think it’d work very well, or if you had less stringent requirements, then you might be able to get it to work . Like some of MSI’s decent B450/X470 boards (B450/X470 Gaming Plus etc.) might be okay with a 3950X OC if you weren’t hammering it and if you had a less aggressive OC or if you had some airflow in combination with some of those other stipulations.
I’ve also included a column for mobos that support BIOS Flashback without a CPU installed, as per this list.
If there’s something in the square brackets for a mobo name. That row includes both the variant that includes whatever’s in the brackets and doesn’t include it. For example the TUF B450[M]-Pro Gaming’s information is accurate for both the TUF B450-Pro Gaming and the TUF B450M-Pro Gaming.
