Budget High Current Power Cords

What makes a power cord high current capable?  I'm just curious.

@hickamore - take a look at Power Cables - ZavfinoUSA

Great technology and a geometry that works overtime at providing fast smooth power

DIY Helix, many recipes, mine uses three or four strands of VH Audio Airlock for hot wire. I've either owned or auditioned tons of PC's in range of $1k-$5k, DIY Helix now the only pc I use in all important equipment.
I'd assume gauge of cable is the critical factor in differentiating high current to lesser current pc. I do change amount of hot strands in my DIY Helix, always min. 12 gauge for neutral and grounds, vary between 11 and 13 gauge for hot.

@williewonka  I assume you still prefer your Helix to the  Zavfino?
