I have found on shopping sites that small PSUs are little cheaper than 500+ Watts PSU.
So I want to buy the lowest one because I have no plans for adding external GPU.
I would be using 2x8 GB RAMs and Micro ATX motherboard (something like entry level B450 or B550). And I would use only stock cooler and no overclocking.
The official docs of this APU says:
Default TDP: 65W
AMD Configurable TDP (cTDP): 45-65W
I am not sure if there's actually a relation between 65W and the Power Supply I need.
Or if it means the minimum PSU you need for this APU is 65W - I am not really sure.
I also found on a site which recommended minimum 300W power supply for this APU without any dedicated GPU. And the recommendation was a little more (350W) if you want to use some entry level GTX GPU like 1050ti.
But they didn't give any reason for this. But this lead me to conclude that it can be used for less than 500W power supply easily.
So, I would like to know what minimum range of power supply unit for this APU. So that it gives quite the same performance which a higher PSU like 500 or 600 Watts would give.
