Nvidia GTX Titan X – External Power Guide
6. Hook up the power board
Now it’s time to attach the power board to your card. Make sure you use as much ground and vGPU as possible. The more – the better. I used 0.5 mm copper sheets to connect everything.
I marked some Ground spots on the front which are quite good to use. You can also use all mounting holes on the back of the card.
Afterwards re-check the resistance between vGPU and Ground. The resistance should stay at about the same level as before. Again, if you have a resistance below 1 ohm recheck everything and don’t power up the card. Otherwise you might damage something.
