What is the difference between 2 x 8-Pin, 3 x 8-Pin, and 4 x 8-Pin 12VHPWR cables?

The 2 x 8-pin, 3 x 8-pin, and 4 x 8-pin versions of our 12VHPWR cables will work with the new NVIDIA 40 Series GPUs, provided your PSU meets or exceeds the minimum wattage requirements. The reason we offer all of these is for users who want extra redundancy for the power being supplied to their GPU.
