I'm mining ETH with multiple graphic cards (over 20). I've researched copper wires and wattage. You guys taught me 16AWG is the wire thickness to use for my cables. Thanks for that.... Here is my question:
Is it best to rewire all my connections using 16AWG Bare Copper Wire (OFA Wire)? (aka "Pure" Copper)This would require a complete manual rewiring (ALL, including 6 pin, Molex, etc). I don't see pre-made OFA wires on the market for graphic cards. I saw nothing on ebay or amazon selling 6 pin wires using 16 AWG bare copper wire (also known as OFA wire). All on the market are either 18AWG CCA wire, or 16AWG using CCA (Copper Clad Aluminum).
For those that don't know CCA (Copper Clad Aluminum) is the copper wire manufacturer's way to cut costs. It combines the 2 metals in the wire. Search on it and you will see what I saw. It's bad.
This video freaked me out:

Am I wrong?
Are OFA wires for mining worth the investment?I ran to my limit of knowledge here.
I was looking at using either Bare Copper Wire (OFA Wire) or 16 AWG Mil-Spec Tin Coated Copper Wire. Apart from the benfits of temperature and longevity, I couldn't find out how much of a drop the tin coating would affect voltage/wattage drop.
