There is no point of getting a 750W bronze PSU. If components need anywhere close to that much power, better invest in gold rated ones. CV650 at under 5k is good for mid-range GPUs, like upto 3060/3060Ti, if you want. But better spend more for a better PSU if you can, will be better, liek Tier B gold rated ones:

This seems to be a new launch, is a Tier B one for a great deal. IMO get this over CV650, worth it. Non-modular though, unlike some higher-priced ones, like CM MWE 650 Gold for ~7k.
650W will suffice upto RTX 3070. Better get 750W gold for something higher, just to be safe.
