The 5-year-old PSU might actually perform better than newer models. If it's functioning correctly, age shouldn't matter much. It's not too weak either. There isn't enough difference in 4K specs to warrant a 7800X3D+motherboard+DDR5 over a 5700X3D or 5800X3D. Perhaps a 4090 would help with troubleshooting? How old is your BIOS version?
Beyond the brand, you need precise models and any obscure numbers or letters attached to them.
