Hi Causing Sloth 766.
My advise, go with the biggest power supply you can get for the specific chassis. It is only a small amount of money compared to all the other parts.
My PC is limited to a 750 w power supply ,as mentioned obowe.
My configuration is as follow:
Asus B460M -Plus TUF motherboard
Intel core i9 10900F 2,8 GHz
Intel 66 SP 1TB M.2 NVME SSD
RAM 32 GB
Nvidia Gforce RTX 3070 , GB RAM
It is running very well all over the wold (60FPS) despite all those software failure we fight with.
