Alright smart people of the internet. I come to you in desperation. I've been at it for hours and I'm entirely lost. I was one of the lucky few that was able to get their hands on a Asus TUF 3060 OC. Brought it home and realized, damn, it won't fit in my M-ATX case. I thought, no problem, I'll just get a mid-tower, I've been overdo for a new case. Order the Mustex TR400 from Amazon, huge upgrade because it had RGB and we all know RGB makes the computer go faster.
Anyway, remove everything from my M-ATX (except the RAM and CPU) then pop it all into the new case. Read the manuals on how everything should be plugged into the MOBO (audio, power switch, etc.) - nothing happened. I thought, weird, maybe the case is somehow causing a short somewhere. I take out my multi-meter and start testing random pins on the board to see if power was traveling through the board. Yep, received some readings, power is making it to the board.
I transferred everything to my old case, plugged it in - nothing. I thought, the PSU is relatively young and I tested the outlet, outlets good. Did the paperclip test on the PSU, yep got 1 rotation of the fan (thought 1 rotation was kind of odd but took it to mean the PSU was functional). I came to the conclusion, it must be the MOBO.
I drive out to Microcenter to purchase a new MOBO (MSI B450 Gaming Pro Carbon Max WiFi). Make it back to my place, swap everything to the new MOBO place it in the new case - Nothing. Swap that into the old case - Nothing. I do some research. I find that if a PSU is emitting inconsistent readings, then a MOBO won't turn on. I thought, maybe that would explain the odd readings on the 24 pin MOBO connector and the singular rotation of the PSU fan after the paperclip test.
I go to Microcenter again, purchase a PowerSpec 850W Gold. Come home, carry my broken buddy to a new outlet that I know works 100%, plug everything in - Nothing again. Is my CPU bad??? That would really suck if that was the culprit because it's just over a year old, but I'd imagine lights would at least turn on if my CPU went bad, it just wouldn't POST. I could be wrong though. Any help or guidance or tests to run would be great.

Old Case - ???
What I've tried so far:
- Tried shorting the power switch pins on the MOBO, still nothing. No lights, sounds, or movement.
- tried removing and replacing the CMOS battery and removing the GPU, still nothing
- I've checked and rechecked my CPU's pins and everything looks fine. No thermal paste on the pins, no bent pins and the arrow is properly aligned.
- RAM has been seated and reseated. I'm down to 2 sticks in the main slots.
- Tested all of the pins in the new PSU 24 pin MOBO plug, all are reading correct voltages
