Hello. I will buy an Asus Prime B450m-a/csm motherboard which has 8 pin CPU power connector and I have a Ryzen 5 2400g, also I have a Gigabyte B700H Power Supply 700W which has 4+4 CPU power connector. 

I bought a 700W PSU because further upgrades like high-end graphics card.

So my question is:

Do I need to connect 4+4 CPU connector to give the necessary power to my Ryzen 5 2400g?

Or

It is enough if I only connect  4 pin CPU from my pSU instead of 8 pin?

The manual says>

Compatible with Intel standard ATX 12V V 2.31

COmpatible with tha EPS 12V V2.93

How much power does Ryzen 5 2400g require?        I know it gives 65W TDP but I do not know how does it work on PSU.

Thanks in advance.
