We’ve all heard the word ‘12VHPWR’ being thrown about – but what actually is it?  

Today, we’re taking a closer look at the 12VHPWR power connectors, highlighting the benefits of this cable, and why you need one in your gaming PC.   

12VHPWR:

12VHPWR is a type of 12+4-pin power connector, used with the brand-new ATX 3.0 power supplies.  

A 12VHPWR connector has been designed utilising premium quality materials to deliver up to 600W of power, all from one singular cable. The combination of 12- and 4-pins will supply plenty of power to your GPU, with improved efficiency.

Why Do I Need a 12VHPWR cable?

These cables have been built specifically for the latest power-hungry PCIe 5.0 adapters, NVIDIA RTX 40 Series GPUs, and ATX 3.0 PSUs. 

These deliver more power in a smaller area, thus not taking up as much PCB space in comparison to traditional 6- and 8-pin PCIe connectors. Any space-saving trick is a must-have for these hefty graphics cards!  

What’s more, combined with an ATX 3.0 PSU, your gaming PC will be able to effectively handle any unexpected GPU power strikes, along with boasting improved efficiency and power consumption.
