Modular PSU confusion

You do whatever you want. 

Use only one 8 pin , or plug both 8 pin connectors if your motherboard has 2  8 pin headers. psu doesn't care, motherboard won't care.

 

If your motherboard has  only 1  8 header, then plug the one connector closest to the psu and leave the other one hanging, unused. 

 

on motherboards that have 2 8 pin header , ideally you use a second cable between psu and the 2nd header, because more wires means less losses, less heating in the wires, in theory it's better. The current is spread across more wires so it's better. 

But if you don't do serious overclocking, then it's not needed to plug stuff in the second 8 pin header.

The manufacturer did not include second cpu cable, so I guess I am just going to plug 8 pins into psu ant 16 pins into motherboard, should work fine. Thanks for the answers.
