We're running in-depth tests on the NVIDIA RTX 4090 12VHPWR adapter cables (the 12-pin cables, sometimes called '16-pin' cables) to see how they thermally compare in different scenarios. A large part of this content is dedicated to testing the current prevailing theory that the solder is weak or that the cable is easy to snap out of place. We also tested a EVGA 3090 Ti 12-pin cable for perspective on thermals versus the modern RTX 4090 solutions. Video cards used include the ASUS RTX 4090 ROG Strix, Colorful RTX 4090 Neptune OC, and NVIDIA RTX 4090 Founders Edition. Cards were tested both stock and overclocked, mostly with FurMark (but also with other tests), and they were tested with 4 different cabling scenarios (stock/unmodified, snapped at both contact points and severed at the lines, snapped at the contact but not severed at the line for overall poor contact (but continuous supply down 12V to PSU), and mixtures of these.

If you have a DEAD OR BURNED cable, please follow the instructions at the timestamp below ("we could use your help" - 11 minutes and 57 seconds) to see about getting us more information. We will not reply to all emails due to volume.

There's more to this story yet. While this is detailed, it is not definitive. We do not yet have a firm answer as to what causes most the failures (or if all cables are affected, e.g. by poor design leading to poor mating at the connector, as opposed to manufacturing defects).
