This doesn't make any sense to me from an engineering perspective...

I have a PSU that is rated for 850W gold+, it is non modular and only has 4 pcie 6+2 pin power cables...

So WHY do I have to purchase a 6 pin to 6+2 pin dual pcie power cable splitter only to recombine the power inside of the GPU???

I mean really... one cable transfers all of the power from the psu to the video card... I split it into two cables (cost of ~$10 USD)... and then assumably the video card recombines that power and uses it for whatever it pleases...

Why don't all video cards just have one 6 pin power plug?
