Hey good felows of Evga comunity.

First of all, thanks, that clicked on this thread showing Your interest in my question/problem.
 
Yesterday obtained evga 1300 psu, but i from the begining knew that i will re make all wires of this psu, thats why i took exactly this one, because its fully modular PSU.
First thoughts, "TOP NOTCH, sweet PSU" and dont get me wrong, i still think the same!
 
But i encountered problem, and i dont know how to get across it.
 

So i totaly want different VGA power cables, sorry evga, yours are good too, im not arguing, but....
The thing is i dont want to destroy or disamble original cables, because im making complitely new cables.
 
And question is in .... why there is 2 power cable wires in one pin, when in PSU goes only 8?
Why (in vga socket) pin 1 and pin 5 has duble wires?
 
And no, this is not a cable 8+6 pin. its only 8 pin cable.
Can i make simple 8 pin wire cable? Like all other PSU cables.
 
Second question is about motherboard power cable.
Thanks to google, dug up this thread, Very useful indeed for lil more enthusiastic users.

So in first this layout didnt made any confusions.
from MB 23 pin to PSU goes 26 pins, easy enought, motherboard pin 2, 5 and 6 splits up.
But now this is different
Looking now at original Evga Motherboard cable it looks as complite mess.
 
in pin 1, 2, 3, 4, 5, 6, 7, 10 and 15 again 2 wiresin one. How so?

Sorry for crapy photo, i just want to be shure that others understand my confusion. 
 
How do i aproach.
 
Thanks for reading.
