Welcome to the forums, newcomer!

My power supply is 750W Gold
750W is the advertised wattage of the unit while gold is the advertised 80+ efficiency rating, what is the make and model of your PSU and it's age?

I also had the problem before changing the power supply of my pc what can I do
You might need to elaborate on this. Did you change the PSU 3 months prior to today?

What games are you taxing the system with? Where did you source said game's installers? What OS are you on? Do you have any overclocks on the system you're working with now? How are you cooling the processor? BIOS version for your motherboard? Make and model of your case and the orientation and number of fans inside said case? What GPU were you on prior to the RTX3080?

My graphics card an RTX 3080 10GB
Make and model of your GPU?

You've been very generic with the specs for your build, it's why I'm having to ask all these questions to fish for possible causes to your issue.

Failure after a time smacks of a heat problem.
More details of your setup would help.

Please note that for the games I mentioned, they crash after 1 to 2 hours when they are on low quality, and the higher the quality, the less time you can play before the crash. The duration also varies depending on the game

 

[geofelt]

That suggests that it is the gpu that is overheating.
What is the make/model of your case?
What is the fan arrangement?
What is your cpu cooler?
What is your room temperature while gaming?

I don't know how to share a screenshot with you, but on Escape from Tarkov, my CPU is around 65-50 degrees and my GPU is also around 65-50 degrees. The game is set to maximum quality settings, and my PC crashes after about 3 minutes of playing. My CPU cooler is a be quiet! Pure Rock 2 Black, and my case is a Corsair Carbide Series, SPEC-DELTA RGB. The temperature in my room is never high when I'm playing
