The vrm on pretty much any B450 board isn´t really great,
except for the Msi itx board.
So i personally don’t particulary onderstand why B450 boards,
are getting really recommend for 3900X / 3950X cpu’s really.
We have seen several tests in which the 3900X was actually tested on the Msi X570 Gaming Edge board.
And the vrm was really performing poorly 115°C,
is definitelly not good at all.
Now given that the vrm on the Tomahawk is actually using the same exact mosfets in the same configuration as the Msi X570 gaming edge wifi.
But the actual Msi x570 Gaming edge board has twice as much phases for vcore.
So i can already tell you that the tomahawk will definitelly not handle the 3900X very well.
Even if the Tomahawk has better heatsinks.
So yeah, a 2700x can use all the way from like 125A ish on load at stock clocks to like 150A ish when overclocked 1.42V.
A 3900X in that regards can easaly hit a 180A ish current draw when pushed.
So yeah i see manny people opting for the B450 boards,
in regards to a 3900X or 3950X.
But i really won’t recommend it to anybody.
The best vrm on a B450 atx board basically is the Msi B450 Gaming pro Carbon AC.
The vrm is actually the same setup as the Tomahawk max.
BUt it has twice the amount of components per phase for the vcore vrm.
