So tonight after dinner thought I'd fire up my gaming rig and play a bit and after an hour I decided to take a break and walked away from the pc for about 10 minutes. I came back to my unit and after a couple mouse clicks I got a BSOD with a Faulty Hardware stop code. The pc then tried to fix itself and rebooted but I heard a bunch of beeps and I quickly shut down the pc. I turned it off then tried to restart the pc and now no posting happens. Regardless of what I try nothing is working but I can see motherboard lights are on. A friend of mine suggested the power supply probably died but as I put in the title this is a less than 1 year old 850w P2 Platinum. I've never run into this before so I have no experience to go by on it. Is there a testing procedure? How do I tell if its the psu or something else? Sorry just not run into this before. 

Try starting the system with your video card removed from the system.

If you are seeing lights on the motherboard it's probably not the PSU since the PSU is giving the motherboard power to turn on the light. It is possible it's still the PSU but I would focus on something else.
 
What I would do is try to make the computer as basic as you can to run windows. Remove all but one stick of memory and unplug all but the C: drive. Check all cables for a secure snug fit to make sure nothing is loose. If the motherboard has on board video use that and remove the video card. The idea is to rule out what could be the issue by having the least hardware in the system and seeing if you get any light code display on the motherboard or what the beep code sounds like. You can also try moving the RAM to other slots or try putting in another stick to see if it's a memory issue.
 
In the event you get the system to boot to windows you can then add hardware in one piece at a time and see if the system boots into windows. You will likely run into the issue doing these steps.

Wow, really weird that mobo doesn't have any video connectors (HDMI, DisplayPort, DVI, VGA) on it so that you can take out the 2080ti and use the built-in CPU graphics in the i7-9700K..If you have or can get an known-good video card, try that..Or try yours in another PC, or take it to a PC repair shop for testing.
 
But clear CMOS and see if that matters.

I have a good EVGA 1080 FTW in a box that I can use I guess. However I can't even get the pc to boot to go to safe mode. 

Definitely worth a try..That could be the problem.

Confirm the outlet or surge suppressor has power - where your plugging in your PC
 
If it is the GPU, then just removing it could allow some power to flow to the MB (if PSU is shutting down for safety reasons)
 
 

I'd test with an old GPU .... again, if your remove the existing GPU ... you can test if PC starts to POST ...this would point directly to the removed GPU
 
cause if your MB or other item has a short ... no reason to put the another GPU at risk

well it isn't the power supply or the gpu..I tried the 1080 and it did the same thing as before and won't post. Guessing that leaves me with a motherboard failure. 

Not exactly. It could be a cpu problem.
 

I'd try removing the cpu, and then see if the board will start and get stuck on a no cpu post code.
