Some RTX 4070 and RTX 4060 Ti may not use the 12VHPWR power supply interface, depending on their TDP

Currently, both the GeForce RTX 4090 and RTX 4080 graphics cards are using the 12VHPWR power supply interface. However, many users who wish to use a graphics card with a 12VHPWR power supply interface still need to prepare a 3*8pin to 12VHPWR adapter cable for their power supply.

According to Igorslab‘s report, the upcoming GeForce RTX 4070 graphics card may have two TDP versions. The higher-end OC version may have a power consumption of up to 225W and will continue to use the 12VHPWR power supply interface. The power consumption of the standard version is expected to be 200W, and the power supply interface may revert to using the traditional 8-pin power supply interface. In addition to the GeForce RTX 4070, the GeForce RTX 4060 Ti and RTX 4060 may also use the 8-pin power supply interface.

While the 12VHPWR can better meet the power supply needs of high-end RTX 40 series graphics cards, it may not be necessary for mid-range to low-end graphics cards. Furthermore, some users have recently reported that the 12VHPWR interface of the RTX 4090 has overheated and melted, giving players the impression that there are some safety hazards. However, 12VHPWR is a trend, and this interface will gradually become more common on new-generation graphics cards.

The RTX 4070 is expected to have two TDP versions:

  • RTX 4070 #1: 225W TDP, OC, 1x PCIe 16-pin (12VHPWR)
  • RTX 4070 #2: 200W TDP, optional OC, 1x/2x PCIe 8-pin.
