How to choose a PSU for the motherboard by additional pins?

Question

Iron

there is such a motherboard https://hard.rozetka.com.ua/msi_x570_a_pro/p100479...
MSI X570-A Pro (sAM4, AMD X570, PCI-Ex16)

it has
1 x 24-pin ATX
1 x 8- pin ATX 12V
1 x 4-pin ATX 12V

but do you need to connect all of these pins or just one 4 or 8 is enough?
I just look at the blocks, there is not even such a thing, either 4 or 8 or 8 + 8,

how to be?

Answer 1

Enough for you (if without overclocking) and 4 + 4 or 1x8. for wild overclocking, you need 8 + 4 - i.e. power supply with 4 + 4x2 most likely. for example https://3dnews.ru/1003014/obzor-chieftec-polaris-7...
