[SOLVED] Additional PSU cable

[LUC993]

Hi,

i am in the process of upgrading my self-built rig. I am upgrading from i7 6700K to Ryzen 9 3900x.

My problem is this:
I built my rig in 2016 and bought a Corsair RM750x PSU for the system. At the time, this model included only one EPS 4+4 pin cable. The X570 MOBO has an 8-pin and a 4 pin socket. I want maximum stability so I would like to have the additiona 4-pin even if(?) i can run the system with 8-pin only, but i don't know where to get it. I tried CableMod, they have a minimum order of 70 EUR (I live in Europe) and the Corsair site doesn't have a compatible extra and most of them are out of stock anway.

I am aware that cables from other brands or even other series within Corsair are not compatible so I am looking for help/ideas please.

Thank you in advance.

no need for the extra 4-pin, that is for extreme overclocking, not necessary.

extra 4 pin should be optional
24pin atx should feed you 265 watts (12v rail)
8pin eps gives another 235watts
4 pin eps gives another 135watts

if your hardware fed from mainboard 12v wont exceed 500watts, u wont need 4 pin
it should be related to overcloking, but too many expansion cards can eat something from this cake too
