Question Crash issue

[Stormu]

Hi everyone, I hope you are all doing great.

Lately i've been having a crash issue which started as some random hangups in some games. I thought it had something to do with game/drivers updates and manage to go on with some options tweaking in games.
Then it became more frequent to the point I couldt play some games.

Issue:
I built this system on early 2022. No overclocking. Ever. No temperature problems.
First year there were no problems at all. Beast of a machine.
Last year or so some random hangups starting showing up.
Last couple of months games usually load correcty to menu, but after a few seconds the pc just stops responding normally, and then a BSOD may occur, with some image glitches beforce hand.
Temperatures wont even get to rise enought to suspect overheating issues.

What ive done so far:
Tried multiple drivers, options.
Removed additional ssd and reinstalled windows 10 (clean install) in new SSD.
Changed mechanical keyboard.
Bios to default (although i havent done any major changes there).
New ram (edit: also memtest86)
Windows 11 (im a win 10 user), same results.
Furmark and Cinebench running at the same time, wont go over 75º and will run much further than any game. Im completely sure it is -not- overheating issues.

Ive downloaded IWInfo but i lack the knowledge to read the results.
At least GPU gets to 250w and CPU to 60w, not enought to blame my 650w PSU, i believe.

Im having a friend bring over another GPU.

System:
Windows 10 Pro 22H2
Ryzen 9 5900x
RTX 3080 10gb
4x32GB Patriot
2x1TB NVMe M.2 Patriot
Mobo Asus Prime B550m-k
PSU Cougart XTC 650 - Model CGR ST-650 - 80 plus.

Id like to have a definite answer, before I think of any replacement.
Ive already tried removing all software variables.
How can i be sure which the hardware piece is to blame?

What exact model of Cougar 650w 80+ power supply is this? Cougar makes a lot of models, but I would be concerned about the quality of most of them.

Run Windows memory diagnostic and see if it returns any problems. You can find this tool through win+s search.

Gonna try it.
Also, forgot in the first one: tried memtest86 too.

If you run out of things to try swap the psu for a quality 750w or bigger unit.

Unfamiliar with that unit but did a little research on it.

588w on 12v rail, so realistically not capable of 650w output for any modern computer. Most likely a very low end/outdated design. It's also only 80+ 230v EU, meaning it's only the very very bare minimum 80+ standard when running at an advantageous input voltage. Not indicators of great quality.

Not saying it's 100% the cause here, but it could be.

Im also deeply suspecting the PSU.
Is there any test I could run, maybe check out some voltages / wattage on HWInfo? Or something else?

PSU Cougart XTC 650 - Model CGR ST-650 - 80 plus.

Group regulated trash, low quality and bad protection features. You definitely need a new and much more modern PSU for this rig.

Even knowing that the first year worked perfectly?
Any way to know for sure before getting a new one?

You think it worked perfectly because there were no visible issues. But the voltage regulation is terrible and the ripple is high. Things you don't see from the outside without expensive testing equipment.
