Default Setup Rm750x to 2080ti lightning z (x3 8pin)

Hi, hopefully a quick one, I just want to make sure i’m Not going to blow any components.

The lightning z has x3 6+2 pin PCIe inputs. My current modular setup on my psu has the mobo power setup the 4+4 cpu connector in the set place and the pcie cable connected next to it.

The pcie cable only has x2 6+2 pin PCIe connectors to connect to the gpu

I have another x2 6+2 pin cable from a different psu. I’m just not sure if it’s safe to connect. It fits in an unlabelled 8 pin socket so I think it should be fine. I just want to be doubly sure.

Any help would be really appreciated!

It’s the 2018 version see link. Looks like the pcie is currently connected in one of the cpu sockets. So it seems like I’ll be fine using the 2 8 pin sockets to the left of the two cpu 8 pin sockets.

However, I’m still looking for an answer to whether it’s ok to use a pcie cable from a different psu?

The 8pin connectors on the PSU end are for both CPU EPS cables and PCIe cables. You should be fine connecting your graphics card with 2 PCIe cables but I would also recommend you make sure you are meeting the minimum wattage requirements of your graphics card. As for using cables from a different PSU we would not recommend mixing cables between PSUs because you risk that cable not being the appropriate pinout and damaging your components.
