Expert Verified By

The demand for high-performance PC components like GPUs is constantly increasing, which, in turn, increases the demand for powerful PSUs. The 12VHPWR cable is a cable of new standards specially designed for power-hungry components. But what is it and whether you need it or not? Let’s find out.


Key Takeaways

  • The 12VHPWR cable is a new standard cable with a 16-pin connector, used to power the more power-hungry GPUs, delivering up to 600W.
  • If you have a high-end graphics unit, such as the NVIDIA RTX 40 series, and are considering buying a PSU, you can buy a 12V cable.
  • If you are not experiencing any issues with the older cables, you don’t need to upgrade to a 12VHPWR cable.

What Is The 12VHPWR Cable?

The 12VHPWR (12 Volts High Power) cable is a 16-pin power connector that can deliver up to 600W of power.[1] In the older days, users widely used 6-pin connectors with a max power of 75W and 8-pin connectors with 150W.[2] 

This newer standard cable takes up less space for graphics units than multiple cables and offers better power transfer efficiency.

Do I Need A 12VHPWR Cable?

Whether you need a 12V high-power cable depends on your hardware configuration.

  • GPU Requirements: Most high-end GPUs since late 2022, like the RTX 40 series, require a 12VHPWR connector[3]. If you have older or less demanding graphics cards, they can often be 6-pin or 8-pin connectors.
  • PSU Configuration: To get the most out of your ATX 3.0 power supply, you’ll need a native 12VHPWR connector.[4] Additionally, you can use adapters to use the cable with older PSUs.

However, if your current build is sufficient and you’re considering upgrading to this cable, there’s no immediate need to switch.
