This is my saga as of tonight.
 
Bought my 3090 FTW3 Ultra in late November.  I used it in my existing PC at the time, and it worked without any problems until this new build.  That PC has a Z370 Asus Prime board (not Z390 that I claimed earlier) with a 8700k and a EVGA T2 1600W PSU.  I build the new PC using a EVGA T2 850W PSU I already had on hand.  I acquired a Aorus Ultra X570 board when I bought a Ryzen 7 5800X.  I could name all the other parts, but these are the important ones.  I moved the 3090 to the new PC, and with the 850W PSU I got only a black screen.  I moved the other PC next to the new one, ran VGA power from that PSU, and it seemed to run okay; everything looked normal. 
 
So I concluded I needed more juice and acquired an Antec Signature 1000W Titanium PSU and installed it.  No more black screen, but most of the time the PC would start up with integrated graphics and while the lights and fans would turn on, the 3090 GPU would not power up.  If I attempted to restart a bunch of times, it would occasionally power up and the PC could run all day, run benchmarks, play games, whatever, but restart it, and you would be back to integrated graphics and restart roulette.  When it was running well, there were initially some AV issues while streaming video, but this seemed to go away disabling Nvidia HD audio.  I use audio over SPDIF or USB, so I did not care about that. 
 
Now frustrated, in disbelief that it was still a PSU issue with 1000W, I removed the 1600W PSU from the other box, set it up outside the new box and powered all of the components from that PSU, and it behaved exactly the same as the 1000W.  I monkeyed with some BIOS and Windows power management and Nvidia power management settings, and there may or may not have been an improvement.
 
Just to keep from going insane, I took the 3090 back out of the new PC tonight, installed it in the old one with the original 850W T2 PSU, and it worked just fine with the Z370 board.
 
So I still have a few days to return this motherboard, and I will.  It may be this one board is bad or something unique to Aorus boards.  It may be the X570 boards are problematic, or it may be that the 5800X is problematic.  It seems like some form of incompatibility.  I don't know, but I can still return this motherboard and try a different one, so I will.
 
That's my story, and I'm sticking to it.  It's not the damn PSU.  Thank you for listening.
 
PS I will add that a 2080Ti works on the Aorus board with all three PSUs.

I can't quote my own post, unfortunately.  But with a new motherboard, the PC starts up as expected, at least several times in a row, before calling it a day and night.  Also unfortunately, I can't be 100% certain of the bad variable.  I received a new MB today, Asrock Taichi X570 (Razer Edition of all things, for the three hyper M.2 slots).  Got it all rebuilt, started first with the 2080Ti, because the 3090 was still in the other box.  Seemed good at first, then replace the 2080Ti with the 3090, and after the first reboot with the 3090, I had no signs that the 3090 was still alive some black screens and audio crackling with the speakers turned on.  Had some frustrations trying to update drivers and BIOS and rage quit.  Went downstairs, lifted some weights, used the treadmill.  De-stressed now, I took the PCI riser and vertical mount off and direct slotted the 3090.  Still nothing.  Found the correct BIOS, flashed them, then the chipset drivers and I was going to be able sleep without rage, because it fired up, 3090 was running and the display was not flashing.  Turned off, connected the second display and restarted.  All good.  Restarted a few more times for grins, and everything looks okay.  Unfortunately, I don't know if my problem was the extension connector for the vertical riser.  I will have to sort that out, because without the vertical mount, my GPU won't fit with the radiator in the normal position.  I can probably come up with a 90 degree bracket for the radiator, maybe get it cerakoted to match the rest of the chassis and modify the coolant tubing, and make it all work and still look good, but it will be a lot of work.  It looks ridiculous now, with the radiator half sticking out the top, held on by two screws, and the power supply just sitting out on the bench (end table).
 
In the end, it's not the power supply.  And I've had my fair share of black screens and fear the 3090 was fried.  The ability to stick it into another PC to verify it was still alive is all that kept me going.  I can't imagine the outrage had I RMA'd the thing prematurely only to have the same problems over and over.

I'm still on my first Asus Strix 3090 OC. No QC here. Plus the design is of better quality. It is my first Asus card in 15 years. 

Strix 3090 its by far the best card to date, no doubt.

Hello oldjsteinhauer! I wanted to let you know I sent you an e-mail to see if we could offer any further troubleshooting or if you had any questions.

It would be nice for you list your system specs and what resolution you play the game at and game settings. I too play 3 older games than you with Skyrim, DA2 and DA:O but I play them at 4k and I override all of the game settings in the NVIDIA control panel with max setting as much as possible. I have had my eVga 3090 FTW3 Ultra for over 4 and half months now and well 1000+ hours in gaming and at least 75+ 3Dmark benchmarks and I also use it for folding at home also when I go to work and when I sleep. I went from a air cooled card to a hybrid card and now watercooling it.

My first 3090 died playing Halo MCC, and the second playing Alien Isolation. Both died within seconds of starting a new game and the system being mostly idle before playing. First 3090 lasted from October through December, second from December until last week. 

It’s too bad. I said several months ago to those that were bragging about their cards working perfectly fine that just a matter of time and It might even take months, but getting EVGA FTW is absolutely wasting of $. Spending $1500-$3000 on a card that will die before even warranty expires is very sad and could even become depressing due to investing all that money just to see it next to go south.
 
I would say to those owning FTW...sell them when you still can and get different brand, save yourself $, but most of all your nerves
 

Does this mean that all evga 3090 ftw or hybrid models are factory defective?

In other words, my RTX 3090 FTW3 ULTRA Hybrid is going to break down ... I hope the evga signature in Europe is good, I have paid a lot for this card and that outside this brand it was very important to me. 
Maybe if my graphics card has not broken it is because I play at 1080p and 60fps. But I imagine that when I play on my future 4k TV it will break down.


Has anyone had a rma in europe?[/code]

For many of us, the answer is simply yes, some are more fragile than others, but ALL are defective at a hardware level.
 
Those of us will continue to believe this until EVGA does the right thing and addresses the problem publicly and honestly with a genuine plan to address the issue permanently for ALL owners. That said I have zero faith evga will do that anymore, they are too busy trying to keep quite and ignore it while simultaneously admitting its an issue by directing CS reps to just instantly approve an RMA as soon as red light is heard or read without any troubleshooting.
 
Still trying to snag a FE card from best buy so I can sell this FTW3.

So, although the FEs seems solid and not prone to dying, keep in mind that they have significant coil whine. I have no idea how much coil whine the FTW3 cards have but from their spec they seem to have more power stages than the FE cards.

Maldita sea, la gente devuelve sus 3090 solo para obtener otro LOL Rip restaurado ... todavía parece que no podré copiar uno.

But are we sure that all evga 3090 models are defective ???
