Any recommendations anyone has would greatly be appreciated.  I bought this system back at the end of 2018 and it really sat for almost a whole year before I started playing and using it.
 
Right now it is hit or miss but I can go a couple hours or an evening with no issues, but other times I can be playing for 30 minutes and will have to do a hard reboot of my computer to fix the issue.
 
I currently have firmware version 90.02.0B.E4 installed and updated to the most recent driver.  This still seems to occur quite often.
 
My P/N is 11G-P4-2383-BR
[SN REMOVED]

Current Temp - Idle 34-35 degrees celsius
Will update under load later

Driver 445.75 - 3.23.2020 release (Just installed today, previously had last 2 drivers with same issue)
 
Power Supply Unit - LEPA G1600 1600W 80 plus gold modular power supply
Graphics - EVGA Nvidia geforce RTX 2080 ti xc ultra gaming 11gb gddr6
Memory - 64GB ram - GSKILL 16GB DDR4-3200 trident z x 4
Memory - 32GB intel optane memory accelerator M.2 PCIE NVME
CPU - I9-9900K 3.6Ghz 8/16 16MB Cache LGA1151 95W

Attached pictures showing how I am currently connected.
 
If I traced right, I am seeing the single connector from the power supply for both connections to the back of the graphics card.
 
Are you recommending I use one plug from the one I am plugged into, and a separate cable from the one next to it, to match 1 for each of the connections going into the graphics card?  
 
I am also going through what look like an EVGA powerlink cable management adaptor
 
I am currently using HDMI output.
 
 

Done, going to give it a whirl.

Ironically it worked last night for about an hour so I thought everything was now good to go.
 
Today I installed the most recent modern warfare and back to the same issue with the game freezing to a white screen or screen freezing and artifacting.
 
If I do a quick reboot, the screen will continue to artifact and load to the OS or eventually just freeze before fulling booting if I do not shut it completely off, wait 10 seconds and then boot it back up.

Unfortunately I do not have a separate system to test it in, nor the means to financially replace it at this time.
 
I think I do not have any other options than to replace the card at this point.  From my purchase date, I have tech support from where I bought it but based on the part number it only had a 1 year warranty :(.
 
Is there any program at EVGA I can send it to just so they could perhaps determine whats wrong that would help them prevent any similar failures in the future?  Happy to donate it if it could help others.
 
Do you think having it on a single rail to begin with could have caused it to fail over time?
 
Appreciate all the help.

Nope.

My 2cents: wouldn't it be easier to pinpoint a graphics card issue vs some other component in the system like mobo or PSU by using a benchmarking software that can target specific components? You can tweak the amount of load applied on the component and then slowly raise them to the point of failure.

I think testing the card by a local PC shop would be the fastest way to determine card failure.
