Hi there, I'd like to know the specs of the power phases on this board. For plenty other models of mbs, it's splattered front and center in marketing material... for this one, you only get the number of the phases on the mobo box (14+1+1 DRPS) but not Aperage info.
From a limited research by number of phases only, the MSI PRO Z790-P have the same setup and 55A.
Is it safe to assume they have the same VRMs?
And to close, is this enough to handle all the intel lineup? (no to moderate OC, with possible UV in mind)
Thanks, Gabriel.

Hi
Both boards have the same base, so it's safe to assume they have the same VRMs too. I don't see why one would have different than the other.
It is more than enough. It's a "Z" SKU motherboard series so they all have enough power to handle all the CPUs from Intel for the series. Since you don't plan to OC, but rather undervolt, then there's absolutely nothing to worry about.
 
In previous board generations, the "Gaming" was always the sign of a higher-up model, but for Z790, it just means they made them look a bit nicer. I talked about it here before. Here are some further general remarks about the board models.

I tried to create a comparison of the board models. Everything that is the better solution is marked in bold font. The better the board, the further down it's listed.
The order of the middle three boards is subjective, but the Z790-S WIFI is clearly the worst, and the PRO Z790-A (Max) WIFI is clearly the best.


PRO Z790-S WIFI: First PCIe slot is PCIe 5.0 x16, CPU VRM only uses cheap discrete MOSFETs, low-end Realtek ALC897 audio chip, 1x USB-C 3.2 (20Gb/s), 4x USB-A 3.0 (5Gb/s), 2x USB-A 2.0, Realtek 2.5GBit LAN, 1x M.2 heatsink, seperate rear I/O cover, smaller VRM and chipset heatsink, 1x HDMI 1.4 and 1x DisplayPort out.
No EZ Debug LEDs, no Flash BIOS Button! Also see here. This PRO Z790-S WIFI should be avoided, the Z790-P is much better already for only slightly more money!

PRO Z790-P WIFI: First PCIe slot is PCIe 5.0 x16, CPU VRM uses 14x 55A VCore powerstages, low-end Realtek ALC897 audio chip, 1x USB-C 3.2 (20Gb/s), 1x USB-A 3.1 (10Gb/s), 2x USB-A 3.0 (5Gb/s), 4x USB-A 2.0, Intel 2.5 GBit LAN, 1x M.2 heatsink, seperate rear I/O cover, smaller VRM and chipset heatsink, 1x HDMI 2.1 and 1x DP out.

Z790 Gaming PRO WIFI: First PCIe slot is PCIe 4.0 x16, CPU VRM uses 14x 55A VCore powerstages, low-end Realtek ALC897 audio chip, 1x USB-C 3.2 (20Gb/s), 3x USB-A 3.1 (10Gb/s), 4x USB-A 3.0 (5Gb/s), 4x USB-A 2.0, Realtek 2.5GBit LAN and 1GBit LAN, 3x M.2 heatsink, integrated rear I/O cover, larger VRM and chipset heatsink, 1x HDMI 1.4 out.

Z790 Gaming Plus WIFI: First PCIe slot is PCIe 5.0 x16, CPU VRM uses 14x 55A VCore powerstages, low-end Realtek ALC897 audio chip, 1x USB-C 3.2 (20Gb/s), 1x USB-A 3.1 (10Gb/s), 2x USB-A 3.0 (5Gb/s), 4x USB-A 2.0, Intel 2.5 GBit LAN, 4x M.2 heatsink, integrated rear I/O cover, larger VRM and chipset heatsink, 1x HDMI 2.1 and 1x DP out.

PRO Z790-A (Max) WIFI: First PCIe slot is PCIe 5.0 x16, CPU VRM uses nice 16x 80A (or 90A?) VCore powerstages, Realtek ALC4080 audio chip, 1x USB-C 3.2 (20Gb/s), 3x USB-A 3.1 (10Gb/s), 2x USB-A 3.0 (5Gb/s), 2x USB-A 2.0, Intel 2.5 GBit LAN, 3x M.2 heatsink, integrated rear I/O cover, larger VRM and chipset heatsink, 1x HDMI 2.1 and 1x DP out.

So the PRO Z790-A WIFI combines most advantages in one board. Except it has no RGB, so to some it might look a bit worse.
But technically it's the best board of these five, and the board model that i regularly recommend even for something like a 14th gen i7/i9.

Thank you all for the help. I thought I checked on the Italian ws and there was the phases but not the amps, I was wrong apparently.

EDIT:
@citay the GAMING PLUS uses the Intel NIC... typing now as I'm just starting to have the dreaded disconnections... man, I was finally putting to rest my 5820k after 10 years, non I'm having all sorts of regrets with this new build

You're right, i corrected it. Which one, Intel I225-V or I226-V? Presumably the latter? My Z690 board has the I225-V and there are no problems.

For the I226-V, apparently there is a fix: https://community.intel.com/t5/Ethe...troller-I226-Series-Random/m-p/1542528#M35302

Consisting of the newest firmware + newest driver. But i guess the new firmware is tricky, MSI would probably have to supply it.
"Please work with your board vendor to find a solution for updating the firmware."

I225-V v3, grabbed latest package from intel and updated via device manager
 
@citay
Done that, also disabled energy and wakeon settings, let's se if it's stable for the next days.
One more thing, even with all wakeon settings disabled in win and on bios, the lan port still blinks orange after shutdown. Is is possible to completely power down the port?
