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.
