Yeah no he's wrong, just look at some of his statements
"
Standard compliant power supply cables from brand manufacturers are NOT affected by this so far."
This is false, cables from Corsair and Be Quiet have already shown to be affected and Nvidia did not design this cable, it was actually designed by Intel as part of their ATX3.0 spec
Here is a Be Quiet cable
Here is a Corsair cable
To be fair, connectors that look like that are quite common - I've seen cables like that since I started building computers across every different type of power connector I've used except SATA.
Cables like that are a quick fix, broken solder tabs on the NVIDIA supplied connector are not.
In fact, I'd wager that those cables used like that without manually fixing/ensuring good seating, would handle more current and generate less heat than the NVIDIA pad soldered crap.
EDIT: This is exactly what CableMod are worried about happening with their connectors too, given the small pin size, hence the "don't bend too close to the connector". Reseating them in these types of cables is possible, fixing the NVIDIA supplied adapters is not.
