Question Screen turns black after playing games for a little while

[Kiwicaprisun]

My PC specs:
CPU: Intel i3 10105f
GPU: GTX 1650
Power supply: some corsair 450w
Motherboard: ASUS PRIME B560-PLUS
RAM: 16gb ddr4
Monitor: 2560x1440 165hz

Long story short my pc randomly started doing this thing where if I play a 3d game; after ~10 minutes it just up and turns black, followed by the fans turning to max until I restart the pc. Ive gotten it to stretch to a few hours of use, but once it starts doing it, it continues.

Ive checked multiple times its not a temps issue.

So far ive tried, clearing cmos, using DDU to reinstall 2 different driver versions, reinstalling windows, undervolting the GPU, etc. When I checked event logs, theres nothing to out of the ordinary besides some applications crashing, then it saying I turned the pc off the wrong way (holding down the button). Any help would be appreciated

Corsair is the brand of the unit, while 450W is the advertised wattage of said unit. What is the model of the unit and how old is the PSU? If it's a CX unit, do you have the green labeled unit or the grey labeled unit?

You might want to source(borrow, not buy) a reliably built 550W PSU and see if the issue persists. Just FYI, your GTX1650 isn't designed to be a 1440p @165Hz gaming card.

Make and model of your case and the temps you're seeing for both CPU and GPU?

I apologize i believe its a CX as you suggested, it does have the green label. Im aware, the monitor was on sale when I bought it, i lower the Res on it.

How old is the power supply you have?

About 4 years old

I apologize, I didnt read the last part... Im unsure of the case, but temps stay under 70 for GPU before "crash" and 60 for CPU (these are while playing sons of the forest)

Find a better power supply from a friend and test it on your system.
Also, the monitor you have with its resolution and frequency is too high for your card.
