Question persisting system shut down under load - Need HELP!

[PC Orangutan 844]

As the title says I'm currently having an issue with my PC that I've been dealing with for a concerning amount of time.

My PC originally started with a

AMD Ryzen 7 2700X (stealth cooler)
EVGA 3070 FTW3
16gb (8x2) DDR4 3200 CL16
512gb NVME
750W BQ EVGA PSU (Bronze)

I built the system in January of 2019 and it ran great for a few years. Then an issue started to happen randomly, where if I was playing a more intensive game the PC would randomly shut off. Like just go running to off in a split second. I didn't think too much of it at the time as it didn't happen a lot and chalked it up to overheating because I forgot to turn on my fans or such. Then the PSU literally blew (smoke came out) one day using it. After that I chalked up the whole issue to the PSU and then bought the same exact model as a replacement but the issue persisted, so I returned it and bought the corsair CX750M. This was about a year and a half ago and at that point my PC usage time dramatically dropped because life became very busy.

My memory is very blurry since then, due to that. I can't remember if it ever did it again or how many times it did it with the new PSU during the few times I've gamed since then. Now in the last month or so I've gained some time and I've tried gaming with my friends but the issue stated has risen again. Specifically when playing , only a few minutes into the match. Every time it happened i had different combinations of fan usage, being the GPU and case fans.

I was just given a new PSU to help fix the issue but before I install it I wanted to see if maybe someone else knew what the actual issue is. I was just messing around on my computer preparing for the PSU swap when my computer shut down without even really being under load. All i was doing was updating a couple things at once on my desktop. With that I'm extremely confused because that would mean its not a load issue either

I believe all my drivers are up to date, I dont think its overheating issue, and now I'm starting to question it being a PSU issue.

If there's any more info someone needs to help me out I can definitely give it.

If you can reproduce the problem, check the cpu and gpu temperatures.
