I built my very first gaming PC last December and I have very low knowledge at the time to know how to do things properly so made a mistake that is quite basic, but stupid.

I bought a GTX 1060 6GB that only requires a 6pins connectors, but I bought my PSU that only provides 8pins PCIE connectors. Its not a problem, however, because the PSU itself is fully modular so I don't have to worry to much about it. For now, the way I power up the GPU is through buying a cable extensions; a 6pins PCIE connector at one end, while the other end is a SATA power drive connector, which is then connected to ANOTHER SATA power drive connector directly to the PSU itself.

The problem right now is that I wanted to do custom mod on my rig such as custom cable sleevings and I was wondering if there is any way for me to make a custom 6pins-to-8pins PCIE connector, to get a clean look without wasting the space on my PSU itself. Meaning that I can actually use the PCIE port directly.

And what are the pins on 6 pins connectors VS the 8 pins connectors itself? Which is the earthing cable, which is the power cable?

I am just starting on modding my own PC so any advice that anyone can give is highly appreciated. Thanks!! 

Here's a pic of it from the side without side panel on. Its a cluster of a mess isn't it

And this is a picture of it with the side panel on. I wanted to add RGB strip in it as a final touch later on, that is why I wanted to do a better cable management mod before I put in any more lighting effects in it.
