Do I need a new power supply?

So I recently bought a new motherboard (MSI z790-A Max Wi-fi)

and it comes with two 8 pin power 

connectors, something that my previous motherboard didn't come with.

I have a Corsair RM750X 80 Plus Gold Full Modular power supply and I check if it was enough power for all the upgrades I was gonna do but I didn't notice that the new motherboard come with extra power pins.

Am I gonna need to buy new cables or a whole new PSU to power this motherboard?

You only need 1 8 pin, it's usually more than enough.

@rippy4500is correct, but it can depend on the CPU and workload sometimes.

I'm gonna go with an i7-13700k and will do video editing with Premiere Pro and After Effects mainly 

Can I just had another 8 pin cable or is that not how it works?

You'll be fine with 1 then.

You would only need two if you had a max overclocked 14900KS or something.

So I'll just plug the same way I did with the previous one and don't worry about the other port than?
