PC crashing only with games

[SilentSada]

Specs:
Mobo: Asus M5A97 LE R2.0
CPU: AMD FX-8350
GPU: EVGA GTX 1080 Hybrid
RAM: 4 4GB g.skill Ripjaws X ddr3
Cpu cooler: corsair h80i v2
HDD:2 WD Red 1tb 5400rpm
PSU: EVGA 600W 80(just bought on June 22nd).
OS: Running Windows 10 64bit on one hard drive, Ubuntu on the other

I've reached out to a few communities(reddit and PCMR Discord). The only thing that's been said is my PSU probably can't handle the load(and that was one person, other people I talked to said that's not the case). My computer is not having heat issues. I ran RealBench stress test for 10mins completely, no issues. When I launch some games my computer completely shuts down. After I have to turn the power switch off then back on to boot up. Running prime95 shows no errors. I've been running memtest86 for 16hours now(done 3 passes almost 4) with no errors. Overwatch, PUBG, Minecraft, my computer crashed playing them. Overwatch it took longer but barely got into Minecraft and PUBG before it crashed. I have no spare parts or another computer to test this in. I had this problem about a month ago(but only happened with GTA V) and thought it was my psu(which made me buy a new one) everything was good until 2 days ago. And I don't overclock.also only critical error in EventViewer says shut down improperly.

One potential issue that comes to mind is your motherboard, specifically the VRMs.
While the LE model of that motherboard is rated to support 125w processor, it really shouldnt be, not only due to poor VRM design, but also a lack of VRM heatsinks as well.
Try adding in, or moving a fan to blow along the VRMs on the motherboard, see if that helps your stability issues. With a typical CPU cooler there is some airflow over the VRMs, but your AIO moves the airflow away, resulting in higher motherboard temps and potential instability on a very low end board.
