8-pin PCIe or 12VHPWR for the RTX 4070, your choice!


As the launch date of NVIDIA’s RTX 4070 approaches, information is slowly trickling in. This time it’s about the card’s power connectors. Igor’s Lab has had some feedback from partner manufacturers.

RTX 4070: two choices of power connectors!

Apparently, for this card, there are two classes of TBP with models in 200W and others in 225W. From there, we can see the picture taking shape: the biggest TBPs for the biggest custom versions with the biggest factory OCs on one side. On the other hand, there would be the small TBPs for the more basic versions.

As for the power supply, Igor’s Lab expects that the 225W models will use 12VHPWR or dual 8-pin PCIe. In addition, the 200W versions could well turn to the old 8-pin PCIe exclusively. Remember that this connector can supply up to 150W on its own. Coupled with the motherboard slot, the power supply rises to 225W. For 12VHPWR powered cards, we can imagine a dual PCIe 8-pin to 16-pin adapter being supplied in the box.

By the way, this pattern would also be repeated for the RTX 4060/Ti where it is not unlikely to see it running with the old connector. The supposed consos of the cards do not justify the use of the 16-pin connector.
