NVIDIA GeForce RTX 40 SUPER GPUs With 12V-2x6 "H++" Connectors Can Support Up To 675W Power Delivery

The 12VHPWR connector has been a topic of discussion ever since its debut and all for the wrong reasons. The connector marked a big flaw in NVIDIA's GeForce RTX 4090 GPUs with cards burning up right and left. This led to PCI-SIG issue a revision under the 12V-2x6 connector design which tried to amend some of the issues but ultimately, it was too little too late as lots of gamers had already bought the graphics card with the older connector design. Cable manufacturers tried to woo gamers by offering right-angled connectors to make plugging in the cable easier without any bends but that didn't turn out well either as CableMod had to recall several thousand connectors which resulted in over $74K worth of property damages.

Well, the new 12V-2x6 connector had silently been rolled out with the older Non-SUPER cards but it looks like its formal debut occurred with the most recent NVIDIA GeForce RTX 40 SUPER series that are mostly equipped with these new power plugs. It should be noted that all three SUPER cards, the RTX 4080 SUPER, 4070 Ti SUPER, and 4070 SUPER have featured the Gen5 connectors but a few 4070 SUPER variants still adopt the standard 8-pin plugs though there aren't a lot of those.
