Yeah I cant believe they used this... but this also means that if you are using properly crimped cable you should be safe - and hence why there are no reports of melting with native cables.This image is just ugh...
The NVidia adaptor is soldered. Every cabling standard that exists has a clause that says "Do not use solder on connections without strain relief". You get a high stress concentration at the joint between solder and no solder, where you'll get broken cores in single digit articulation cycles...
It's literally 101 of cabling and connectors. You use a crimping tool or you don't use the connector.
NV deserve BIG heat for this. Unimaginably dumb.
