Cable Sleeving Guide

If one or two or all does not mind - they are connected on the graphic card PCB
But as I said before:
Technology is so good today that this caps are not necessary...
Just think about the the PSUs without any of these caps (under 7-800W) that can also power these cards.

If you want to know it in detail:
A capacitor can save energy (when the voltage goes up) and can give this energy away again (when voltage goes down)
A too weak PSU that runs at 11V couldn't get 12V through these caps. In this case you need another PSU.
Only if there is a short extreme peak it helps a little bit to hold the voltage at the same level.
But there still are enaugh caps in the PSU to manage the biggest GPU.
