1080 causing PSU to trip

I have two 1080s and on one of them every time I connect the 8pin connector, it trips my PSU like there is a short.  I have tried plugging the card into different power connections on the PSU.  I have even tried removing the card and plugging the power with it disconnected from the motherboard.  Both cards are water cooled.  During my troubleshooting, I removed the water block and noticed that it looked like a couple of the memory thermal pads were not making good contact.  The card has been running non-stop fine since Aug 2016.

 

Has anyone run into this situation or know if a bad memory chip could cause this issue? 

 

Here's a little history.  The motherboard I am using is an EVGA X99 FTW K with a 6850K CPU.  I also have a PCI-ex sound card.  Since I did not want to reduce the lanes on either of the video cards to 8x, I needed to use the 1x slot next to the top 16x slot.  To be able to use that slot, I had to remove the DVI connector on one of the cards.  So since I removed the DVI connector, that of course voided the warranty.  I mainly wanted to make sure I don't repeat any mistakes.

That's the sound of a PSU going bad. I'd probably not turn the system on until there's a quality PSU in there, like an 800W Corsair or Seasonic unit.

 

edit for a while it said Seagate instead of Seasonic. derp

Ye ole' train

What PSU are we talking about?

If you have a multi rail PSU make sure every connector comes from a different PSU rail so you don't hit overcurrent protection. It may be as low as 17 amps per rail in some units, so a 1080 alone would trigger the OC-protection instantly. 

 

Grab manual, see if this is your case. You could be sharing the cpu rail in one end too.
