Looking to buy some new equipment, and the Be quiet! ‎BN641 PSU I have in mind, it says the below.

Please make sure you balance the load across the 12 volt rails 12V3 und 12V4:
When using two PCIe cables, connect PCIe 1 and PCIe 3
When you only need one PCIe cable, connect PCIe 2

The 4080 I am also looking at would need. (Im pretty sure) the above doing, I just dont know what it means.

I appreciate any help on this, I have looked online, but cant find the answer.

Thanks.

this is a modular power supply.
if 2x PCIe power cables are needed you plug them into the power supply's 1st & 3rd slots.
if using a single PCIe power cable you would use only the 2nd slot.

look at images of the power supply itself and you will see how the cable slots are labeled.
