The four small pins of the new connectors are significantly shorter than the old ones. In other words, they “snap” only when the connector is fully seated in the graphics card.
GeForce RTX 4090 16-pin (12VHPWR) adapter overheating issues are mainly due to bad connections ; at least, that’s NVIDIA’s public position. In recent weeks, however, this case has had new twists: a (unique) case of melting of the connector, but on the power supply side; revamped GPU designs including Gigabyte’s RTX 4090 WindForce; two-tone cables, like those of MSI. Above all, from the GeForce RTX 4070 Ti, NVIDIA has discarded certain connector models. The GeForce RTX 4070s also have a new specificity.

As shown above, the 12VHPWR connector on the GeForce RTX 4070 Founders Edition has shortened data pins. These are used to define the power delivered by the cable; consequently, they restrict the power if the connector is insufficiently inserted. According to our colleague Igor Wallossek, the interior space used to be 0.45mm (species between the outside and the end of the pins); he is 1.7 mm for the GeForce RTX 4070 FE.
Changes also for custom maps
According to Igor, partner custom graphics cards also incorporate this design change from the PSU designers (called H+). In any case, this allegation is proven for two copies he has on hand: the MSI RTX 4080 Gaming X Trio White which has “long” pins, and the MSI RTX 4070 Gaming X Trio with shorter pins. Inevitably, for this last reference, the proper functioning of the four pins requires a perfectly inserted cable.

Neither NVIDIA nor MSI or other brands have communicated on this subject. Discreetly, companies have therefore changed their conception; from there, and even though it’s just an added protective feature, it’s hard to deny that there was something wrong with the early connector designs…
