Hi,
I recently purchased an X570 Extreme 4 board and noticed it has 8 and 4 PIN CPU EPS connectors.
Is it necessary to have BOTH connected or will just the single 8 pin suffice?
I am running a Ryzen 3600 stock with no overclock.

Regards
Sam

There is no need to use the 4 pin connector with the Ryzen 3600.

Many thanks, this is the offical reply from Asrock:

Hello,

Using a single 8-pin connector is fine. The additional 4-pin connector can be useful for more extreme overclocking.

Kind regards,
