NVIDIA RTX 4090 Power Connector Reported Burnt Even Without 12VHPWR Adapter

Yet another report of an RTX 4090 meeting its end due to faulty power connectors has surfaced. Interestingly, this user claims they used a 16-pin ATX 3.0 power connector directly from the PSU rather than a 12VHPWR adapter. The card in question is the MSI Gaming GeForce RTX 4090 Gaming X Trio powered by the MSI MEG Ai1300P, a PCIe Gen 5 grade power supply with ATX 3.0 support.

Although the damage, in this case, is less than in previous examples, it’s still far from acceptable. The fact that there was no bending of the cable nor the use of a tertiary 12VHPWR adapter indicates that this may be a more complex issue than anticipated.

OEMs selling PCIe Gen 5 power supplies may very well be forced to recall the PCIe power cables from customers and provide them with a free replacement as soon as NVIDIA discovers the exact reason behind the fires.
