The 12V2x6 Connector Is Capable Of Delivering Slightly More Power Than 12VHPWR Does
When NVIDIA upgraded its GPU to use the 12VHPWR standard, it didn’t take long for the new 12+4-pin connector to gain notoriety due to its tendency to melt and burn cards along the way. Many dead GPUs later, a solution in the form of 12V2x6 was silently introduced to gradually replace the original connector.
While it is simply known as a fix for the troubled power connector, the 12V2x6 was recently discovered to be actually capable of delivering slightly more power than the original connector does. For reference, the 12VHPWR connector can deliver up to 600W on a single connection, which is significantly more than the 150W from the legacy PCIe 8-pin connectors. This new connector, meanwhile, will deliver 675W – meaning a GPU can theoretically pull 750 watts when combined with the extra 75W supplied from the slot.
However, it’s not exactly easy to tell the two high-power connectors apart, and neither NVIDIA nor PCI-SIG has provided any clear indicator that a GPU may use an updated connector. However, user @wxnod has found a small marking indicated on the female receptacle of both 12VHPWR and 12V2x6 connectors, with the former labeled as “H+” and the latter “H++”.
H++ 12V-2X6 (max:675w)
H+ 12VHPWR (max:600w)

The new connector has since found its way to a newer batch of GPUs, including the recently launched NVIDIA RTX 40 SUPER series. However, some SUPER cards are known to use the old “H+” connector. In most cases, you’ll have to manually remove the GPU shroud to see the markings – but don’t fret if your GPU comes with an H+ connector, as most cases of melting connectors occur specifically on the power-hungry RTX 4090.
Still, if you want to be absolutely safe, just make sure the connector is properly seated, regardless of what type of connector it may use.

Pokdepinion: That should allow some margins for GPUs to shoot up to 600W – but would NVIDIA try?
