Newly built PC shutting down while gaming, power button only works after power cycling the power supply

It's a bit of a wall of text, but before I go crazy replacing parts I want to get a second opinion. What I'm currently looking into is a new PSU, like the EVGA G3 750W, even if it is overkill in the Watts department. If there's still an issue, I'm not sure what to be suspicious of, other than the GPU. I've already used the Display Driver Uninstaller once, and then reinstalled the recommended driver.

I'm not too clear in the first place if there is something else other than a faulty power supply or overheating, that could be causing a sudden PC shutdown.

Parts:
CPU: AMD - Ryzen 5 1600 3.2GHz 6-Core Processor, using Wraith Spire cooler
Motherboard: MSI - B350M GAMING PRO Micro ATX AM4 Motherboard
Memory: Team - Dark 16GB (2 x 8GB) DDR4-3000 Memory
Video Card: Gigabyte - Radeon RX 580 8GB Gaming 8G Video Card
Case: Phanteks - ECLIPSE P400 ATX Mid Tower Case
Power Supply: EVGA - 500W 80+ Certified ATX Power Supply
Monitor: ViewSonic - XG2401 23.6" 1920x1080 144Hz Monitor
Storage: M.2 SSD, 256GB

Built a few days ago. Nothing is overclocked, and I'm using the latest 2.6 BIOS and other drivers, as far as I can tell. The PC will suddenly power off without warning while gaming, and will have a event ID = 41 after rebooting, in the event viewer. The details are all 0, and at first, the most likely culprit to me was something overheating, or some kind of PSU issue. I have been pretty cautious about overheating because the PC was at first in the cabinet of my desk, with the door removed and an open back. A little bit ago I removed it from the desk and put it on top, out in the open, to remove overheating as an issue.

Before and after doing this, all of the temperatures in HWMonitor were outside of dangerous ranges, up to the moment the PC shuts down. I haven't seen the CPU reach 70 C outside of Cinebench or the FurMark CPU burner stress test. For the GPU, the temp is only in the high 70s C while gaming, and before it shuts down. Using FurMark, the temperature eventually reached, and stayed steady at, about 88 C before I lost patience. Overall, I haven't seen any dangerous numbers while gaming, and I haven't been able to cause a shutdown with stress testing, even when the numbers are higher than the moment before a shutdown during gaming. The 3dMark demo and Heaven Benchmark 4.0 also didn't show me anything new. SInce I can't see if the PSU itself is having heat issues, I'm assuming there are none because it is now out in the open.

The first issue was an extremely loose power cable for the PSU, to the point that touching it where it connected was pretty likely to shut down the PC. When the PC started shutting down while gaming, I assumed this was the cause. After bandaid fixing this by switching the PSU and monitor power cables, it became clear that the issue wasn't with that connection failing, because it still kept happening.

If I want to crash within a minute, I just need to open Path of Exile and run around outside town for 30 seconds. Another game I crash in is Borderlands the Pre-Sequel. It seems like it will crash eventually if I play long enough, but I can't find much that is consistent about it. I've had it work fine for at least two hours while playing with friends, and the next day it crashed after 1-2 hours. After that crash, when I immediately power cycled the PSU, rebooted, and rejoined, it happened again within a couple of minutes, and did the same when I repeated it about 5 times. To me, this makes it seem like some kind of overheat, but after putting the PC out in the open, the problem continued, at least in Path of Exile, since testing it in Borderlands takes too long (I did run around for about 10 minutes without issues).

I plan to try playing some other games, to see if the issue also happens there. I was able to play Overwatch for about 4 games with no issues, but I haven't tried it since. Basically, my conclusion is to definitely replace the power supply, and then start suspecting the GPU if issues continue. I'm not sure if an issue with the GPU could be causing this kind of problem, but at that point I don't know what else to do. Hopefully, I'll be more confident after testing out a few more games.

Also, I'd love to hear it if there's a great quality PSU that I can trust, with good reviews, a lower price, and less wasted watts.

Upgraded to the EVGA G3 750 today, and no issues in games that near instantly shut down the PC earlier.
