How many PSUs do I need to run a mining rig with 12 Radeon VII GPUs?

[fxs]

Hi all, my first post so forgive me any trespassing. I want to build a mining rig with 12 RADEON VII GPUs and would like to know how many and what Wattage PSU's do I need? Will I be able to run this form a single 110V wall plug? If as I suspect the answer to the 110V wall plug is a giant laugh that will reverberate across the internet... What is the best way forward? This is my first full blown rig so I have very limited experience/exposure to mining rigs. I do have a prototype I cobbled together with 4 RX 570 8GB and wanted to move up.

12 x TDP295 W so 295 x12 =3,540 plus the motherboard etc its saying Suggested PSU600 W for 1 card so i add another 305 watts for because it suggests 600 for the system but -295 because i already worked it out via cards tdp, so probably 3,845 watts 2x2000 watt psu's should do it, you might get away with a 1500watt and a 2000watt. PSU's always work most efficent under 50% load.

You need to know at what wattage those RadeonVIIs will run under mining and properly configured (VRAM OCed and GPU underclocked and undervoltaged). Stock TDP is pretty much irrelevant as most cards when configured optimally are drawing around 60~70% of their official TBP (Total Board Power).
I don't know exactly at what wattage each card will land after optimization. Could be 200W or 250W... of the ~300W official power draw.
12 of them could be 2500W or 3000W. Rest of the system depending on the hardware could be 50~150W.

My educated guess would be that you'll need a total of 4000W with a consumption of 2500~3000W. You don't want to load the PSU(s) more than 70% for the efficiency and longevity.
And they should be 80+ Platinum rated and high quality for them to able to run 24/7 with 60~70% load.
