Hi everyone, I just replaced my motherboard and it now has extra space for power cables. My PSU isn’t modular and didn’t include additional cables, especially since I’m building a prebuilt PC. I noticed the PCI-E cables for my graphics card are identical and have two connectors. Would it be possible to redirect the cables from the graphics card to the motherboard and vice versa? Thanks for your advice.

They don’t match up because the CPU and GPU power cables have different connectors. You likely have a X570 board, so the extra CPU power connector is meant for extreme overclocking. It only needs an 8-pin connection.

Please share the details of your system: the motherboard and power supply unit brands and models. (Excluding OEM boards like DELL or HP) Your board should have four EPS connectors, typically two, while your graphics card uses PCIe connectors—either 6-pin or a combination of 6+2/8 pins. Let me know if you'd like help identifying the exact models from a photo or specs.

The PCIe power connector fits mechanically into an EPS port, yet it won’t connect properly.

It will also cut off the board and power source if he does that

I understand why I mentioned it wouldn't work. I was responding to someone who said it wouldn't fit at all.

The mainboard is an MSI X470 Gaming Carbon Pro and the power supply is an EVGA 650W.

It could fail due to inconsistent power usage across cables. Each connection might draw a varying amount of current, leading to overheating or instability.

You link the ground to a phase, which is what causes a short circuit. You’ll deliver 12v where there shouldn’t be any current (the ground connection).

Are you referring to these? Unless you're LN2 overclocking, you don't need both.
