pci-e slot minimum voltage

I keep having issues with cards I test. AMD cards will just crash after 5-10 minutes, powered or unpowered. 
Nvidia powered card will go forever
Nvidia unpowered card will sometimes crash, I had two crashes so far on the card I just got, but then it seemed fine for over 30min.

 

I'm trying to track down potential issues, and I have noticed the pci-e slot power dips to 11.7-11.8 in games and a fairly steady 11.6 in furmark.
I didnt notice this before with other cards because none of them report this info in gpu-z. 

But I cant seem to find info on if this is in spec or not.

What board do you have, and what PSU?

I'm not actually trying to be as grumpy as it seems.

Why is the 5800x so hot?

oh i guess that would work too, I was more wondering if nvidia or amd had any specs of their own. 
by that chart I'm still within spec by a small margin

ATX specification is ATX specification. Nvidia and AMD go by ATX spec. 

What GPUs are you using? You said Nvidia powered and Nvidia unpowered? They'll all take power to work. What enclosure are you using?

I meant powered as in takes external 6 pin/8 pin/whatever

current card I just got is a gtx 1650 straight out of a prebuilt dell with the shittest cooler you could ever imagine, past card was a 770 which is pretty solid but not as elegant of a setup. 
I've tried a heard of GCN era amd cards and they all just disappoint and I didnt want to waste money trying newer ones. 

the 1650 works so far now so it could have just been maybe temps, it never got over 75c much on core but maybe memory/vrm get hot. All I changed was increase fan speed and maintain 65c I still need to test further I guess as I only just got the card a couple hours ago. 

 

enclosure is some akitio thing

It was voltage related. 
I switched to a different power adapter and the problem sort of went away. 
 

The issue is in the design of the enclosure itself, even using a 200w power supply adapted down to the barrel connector would sag the voltage just as far so I think I need to replace the socket with a higher current one and run additional wires or sand back the traces and thicken them up with solder. 
The disconnection was something to do with the enclosure's controller hitting minimum voltages.
