NVIDIA Introduces Enhanced 12V-2x6 "H++" Power Connectors in GeForce RTX 40 SUPER Series

NVIDIA has launched an upgraded type of power connectors, the 12V-2x6 "H++", in its latest GeForce RTX 40 SUPER series graphics cards, promising improved power delivery up to 675W compared to the previous 12VHPWR "H+" standard, which maxed out at 600W. This move comes after issues with the 12VHPWR connectors led to failures in GeForce RTX 4090 cards, causing significant material damages and prompting a design revision by PCI-SIG.

Although the "H++" connectors were quietly introduced in the older Non-SUPER cards, their official debut was made with the NVIDIA GeForce RTX 40 SUPER series. It is noted that all three SUPER cards - the RTX 4080 SUPER, 4070 Ti SUPER, and 4070 SUPER - are equipped with these new connectors, though a few variants of the 4070 SUPER still utilize the standard 8-pin plugs.

The 12VHPWR connector issues forced cable manufacturers to offer alternative solutions, such as right-angled connectors to facilitate easier cable insertion without bends. However, these attempts were not entirely successful, leading CableMod to recall thousands of connectors after incidents resulting in over $74K in damages.

It's important to highlight that while some GeForce RTX 40 SUPER models still feature the "H+" plug, the major burning issues were primarily observed with the GeForce RTX 4090 cards. The use of previous specifications should be safe for other cards, but users are advised to ensure that the connectors are properly inserted into their GPU for optimal operation.

The introduction of the new "H++" connectors indicates NVIDIA's commitment to enhancing the reliability and performance of its graphics cards, as well as preventing a recurrence of the problems encountered with previous models.
