No.

 

You also don't need the extra 4 pin, all AM4 chips can get enough power from just the 8 pin, it can deliver up to 244W.

This has probably been asked numerous times before but do you need to connect up both the 8pin and 4pin cpu power on a board like this?

I've got an RM650X that only has the 8pin

 

Cheers.

Usually the 8-pin is a definite and the 4-pin is optional for extra power and overclocking.
