If there is is interest in those VRM chips, I could always take a pic of those.

Probably all On semi like other b350

Br0da loves pics. May already have. His vrm list has the mortar with RT8894A controller and PK616BA highside , 2 PK632BA on the low.

There've been a few motherboard models that have used different components. One mobo, escapes my memory at the moment, seems to be using at least two different sets of fets.

Here's some shots of the VRM's:

http://www.overclock.net/content/type/61/id/3004284/width/350/height/700

And the whole board:

http://www.overclock.net/content/type/61/id/3004286/width/350/height/700

To my surpirse, the main VRM heatsink is attached by phillips-head screws... Being a budget board, I half expected push-pins. If there is is interest in those VRM chips, I could always take a pic of those.

It'd be a decent mATX board for the money if they changed the I/O to include USB 3.1 Gen 2 , possibly added some shielding onto the audio (ALC892), and ditched DVI-D (this is probably kept in similar fashion to how other manufacturers kept VGA port). The Realtek LAN is a fairly reasonable compromise for B350 , it isn't a huge deal. Given the lackluster mATX options it's a solid choice however.

That looks to confirm br0da's list with PK616BA highside and PK632BA lowside.

The side you uncovered appears to be the SOC side. The CPU VRM side should have a doubled low side,

It's the Asrock X370 Fatal1ty K4 & Killer SLI . Uses a Sinopower SM4336+SM4337 OR NIKOS PK618BA lowside + unnamed mosfet high side.

My awesome Killer has the Sinopowers - both of my K4s have the Sinos as well - I wonder how many actually had the Nikos?

I hear you, man. A few years back I was confronted by the same choice: have one of my best friends "go to sleep", or have her suffer on for who knows how long. I still miss her to this day, and even thinking about her brings tears to my eyes.

Take care, Chew.

gents,

given what we know of the mobo vrms quality and the price gouging i see from my local stores (prices below), might i ask if the asus prime x370 pro is the best value if the goal is a 3.9-4.0ghz daily driver?
i'm cooling the r7 and gpu with a custom loop, with a radiator on top to pull out hot air. not sure if that helps much with cooling the vrm though.
taichi is what i got my eye on but asrock isn't in the market yet and rep isn't sure if or when they are coming.

local prices:
Asus Prime X370 Pro $196.85
Asus ROG Crosshair 6 Hero $341.90
MSI X370 Xpower Gaming Titanium $326.56
Gigabyte Aorus AX370 Gaming 5 $237.10
Gigabyte Aorus AX370 Gaming K7 $264.99

Yeah, the asus prime is the better deal there.
