Question Computer randomly shuts down.

[DaJagerBomb]

Honestly i don't really know how to word this. i bought a build from my buddy cause i know a bit about computers but he said it needed a new PSU well i bought a brand new Corsair Vengence 650m psu and it is still shutting off. it runs without a hitch until you load a game like apex about two minutes into the tutorial its shuts down but doesnt restart just stays shut off but i can search the web for hours. I don't know what else to check.

SPECS:
MOBO; ROG STRIX 8450-F Gaming
CPU: AMD Ryzen 5 2600 Six-Core Processor
Video Card: Radeon RX 470 Graphics
PSU: Corsair Vengence 650M (650W)
Ram: 8.0GB G.Skill
Please Help

check cpu/gpu temp during the game?

i deleted apex cause i figured it didnt work why have it but im using OCCT and ive run it on CPU:OCCT on small load and medium load and it hasnt shut off yet

 

[DaJagerBomb]

should i run it through all tests and see which ones shut it down?

 

[DaJagerBomb]

the cpu has stayed right around 50C and the gpu reached 64C on the large data set test on CPU:OCCT

i did a Linpack test at 65% memory and it lagged a bit but didnt crash. same thing for the 80% test

so i did a power supply test and it crashed but i noticed none of the components actually shut down like all of the led's were still on and all of the fans were still spinning just the keyboard mouse and screen shut off if that helps narrow it down. the thing that makes me think its not the power supply is that i literally bought it a week ago.

could be the gpu . got another one to test?

also uhhh i noticed right before it crashed in the the last frame there was like a red and black circle right in the center of the screen. then it went black???????

 

[DaJagerBomb]

i do not.

 

[DaJagerBomb]

honestly it looked just like this so would that be my gpu failing

I ran a GPU stress test and after 1.5 seconds it crashed and now it starts up but there's no signal to my monitor keyboard or mouse
