The adapter, which is seemingly manufactured by an organization known as Astron and was offered by Nvidia to all of its board companions, makes use of “a complete of 4 thick 14AWG wires distributed over a complete of six contacts,” with a skinny solder base that Wallossek says might be broken simply when the cables are moved or bent.

The solder inside of Nvidia's power adapter cable can be damaged if the cables are moved or bent too much.
