6700xt display port no signal

I switched GPUs today from a 5600xt to a 6700xt. 

I'm stuck with a black screen. It seems like a common problem but the videos I've watched and things I've read seem to not help. Most of them are still able to see their monitor and update drivers/mess with bios etc. Mines just a black screen. It works when I swap back to my 5600xt. 

My specs are as followed. Any help would be greatly appreciated.

AMD Ryzen 7 3700X 3.6 GHz 8-Core Processor

AMD Random 5600xt

NZXT Kra ken X73 73.11 CFM Liquid CPU Cooler

What was the solution?  This could be a learning experience for another builder.  Was the Display Port cable good?  Did you have several Display Ports to plug it into on your new video card?

As Albert Einstein said, "I could have done so much more with a Big Al's Computer!".

User error.  First time swapping to a GPU with two PCI-E ports. I thought the PCI-E cable thats split would work for both ports. Figured it served that purpose when it doesn't at all. 

Had I read the first line in the book that came with the GPU I would have realized power issue. 

Ran another PCI-E cable from my PSU to GPU. Booted right up 0 problems. 

I felt so dumb its embarrassing.

I don't refer to it as stupid, you experience humility.

As a network administrator I had the same identical situation with a new D-Link network card.  Just installed it and connected the cross-over patch cable and NOTHING.  It wouldn' see the network and the network wouldn't see it.  Just prior to returning the card I thought, maybe I had better read the manual.  Sure enough there it was in the first sentence, "a straight thru network card".  I still get a laugh out of it.  Those are what you call "lessons learned".  Everyone on this forum has experienced them.
