At this point just recall all the bloody cards and switch back to the old connector. Don’t care if just 1% or less are melting, it’s still too much when it could risk a fire.

They won't do it unless really forced by law to do it. That would mean huge losses for them and Nvidia never lets it's money run away.

A recall's also pretty dismal for customers as well, unless there's no other option. If this can be solved by shipping a replacement adapter, or via other means, then that's got to be the way to go.
 
Nvidia's director of engineering has provided a small update

There are two companies who manufacture 12 pin HWPR connectors for Nvidia and Nvidia encouraged all its partners to use them as well and it's looking like one of them has issues. The company who makes the adaptor with issues is called Astron and the other is called NTK (the Astron connector may not latch on properly and can have a measurably higher resistance than NTK, sometimes exceeding it's rated 2ohm resistance). As a result, Nvidia is switching to using just NTK. Nvidia has not finished its testing yet but that's where they are at for now.

NVIDIA confirms there are two manufacturers of 12VHPWR power adapter cables - VideoCardz.com

There are two manufacturers of NVIDIA’s 12VHPWR connector, and you should probably avoid one Igor’sLAB is working tirelessly to get to the bottom of the 12VHPWR ‘melting’ problem reported by many users already. The latest development is a discovery that there are two manufacturers of the NVIDIA...

is there an easy way to tell without unplugging it

images of the connector from behind and underneath would have been nice.

I can't be bothered to unplug and turn off my pc to find out

EDIT: Seems from reddit both types have "melted" anyway

I think the resitance they are talking about is through the connection point of the mating surfaces and the resistance is pretty low, even when its on the high side of the range.

I don't think this is something that would be practical for end users to measure.

I asked Zotac if I could use a cablemod cable. They said NOOOOO
So I asked them again and they said YES

But I don't trust them if the cablemod does burn.
Zotac will blame them.
 
As long as the cable is made to specification, they can't really argue the warranty.

Aftermarket PSU cables have been around for many years so providing Cablemod made them to the new specification and you inserted it and used it in line with the nvidia guidance (re bend radius) then you have nothing to worry about. Don't go crying to them if you buy a cheap chinese cable off ebay though :p.
