Question Help with a System Diagnosis Nightmare?

[Minty Mentos]

Okay Specs List first
AMD R5 3600
16gb DDR4 Corsair Vengeance
PNY GTX 1650
Gigabyte B550M Aorus Pro-P Mobo
Thermaltake smart 500W (80+ Basic)

Explanation
Was playing valorant, PC randomly shuts off, try replugging and turning back on to no fan spin.

It's my first build so forgive some of the stuff you're about to hear

(Grounded by wristband entire time)

Opened up PC, Reseated Ram, Nothing (ram 2 was not seated right though!!!)
Removed ram 2, no post
Replaced PSU with another PSU since I took a closer look and noticed one of the blue things inside PSU had busted (note that I'm not sure if a surge would be an immediate answer since I had PC connected to a surge protector) Fan Spin but ramps to 100/no post
Keep using replacement PSU for following tests
Reseated GPU, Fan ramp no Post
Different cables, same thing
Placed GPU in 4X slot, fan ramp no Post
Replaced GPU with spare GTX 660, No post, seems the fans ramped up less though? (Not sure if it's the GPU fans being so loud on my other GPU or something else, CPU and case fans did a thing where they spun, momentarily idled, and then kept spinning)

That's about where I am right now, I have to go to work now but when I get home I'm gonna try more troubleshooting. My thought is RN is PSU died and took GPU with it. About to test GPU in spare PC when I get home. Any help is greatly appreciated, thanks!
(I can provide more info if needed but may be delayed)

Thoughts:

Surge Protectors - surge protectors can only absorb a certain amount of "excess" energy. Measured in joules. If your location (not asking) has lots of power problems then the surge protector may have reached its' limit and is no longer functional.

PSU(s) - if modular did you only use the cables that came with the replacement PSU? 500 Watts may not be enough to support peak demand loads while gaming. Especially if the PSU has a history of heavy gaming use.

RAM - some motherboards require that the first physically installed RAM be placed in a specific RAM slot. Check the motherboard's User Guide/Manual.
