Wraith - when I received my 3090 FTW3 Ultra I was having the same issue with a 1000w Silverstone Strider PSU that had been fine with my 2080 TI FTW3 Ultra. I thought no way it could be the PSU but as a last ditch I bought a new 1000w eVGA PSU and it has been solid since.

I hope you figure it out.

So I just got my 3090 a few days ago and I have experienced some hard pc crashing. I have to toggle the PSU switch in order to boot after a crash.

Specifically playing Escape from Tarkov. I don't have any rtx enabled games as I just upgraded from a 1080ti FTW3.

System Specs:
ASUS Rog Crosshair VIII
Ryzen 3900x - no oc.
NZXT Z73 Kraken AIO
2x 16gb 3600 DDR4 CORSAIR VENGEANCE running xmp settings.
Thermaltake Toughpower Grand RGB 850W 80+ Gold(pushing 4 years old now)

9x Corsair LL120 120mm fans
CORSAIR RGB LED Lighting PRO Expansion Kit

Storage:
2x nvme ssd
2x samsung evo ssd.

peripherals
Corsair Void Pro headset
Corsair Strafe keyboard
G502 Lightspeed mouse
Amazon basics speakers
Lian Li Strummer Plus 24pin
Sabrent USB 2.0 Sharing Switch

Side note: I ordered some custom pcie cables from CableMods for the 3090. I got 3x pcie 6+2 cables for my PSU, based on their cable generator.

So I got my card on Thursday, got it installed and using the new cable mod cables. Once installed I power up with no issues.
Made sure my Nvidia Geforce drivers were up to date. (I don't have the super latest that Jacob posted about yet)

Installed PX1 and did the firmware update. Right out of the gate, I tried the oc scan, and It just failed. So I ignored that for the time being until I had more time to research into it.
Ran a few raids in Tarkov, no issues.

I used my PC all day Friday for work (rdp to another work station) no issues.

Later in the night, I played Tarkov for roughly 3 hours. I started running into the crashing when I attempted to load into the hideout. Just instant shutdown. No sensor warning/beeping, nothing. Just off. The power led on my case was still illuminated. I had to toggle the PSU switch before I could boot again.
From there, anytime I loaded Tarkov and went into the hideout, full system crash. I tried to have HW monitor and gpu-z open and watch for anything but just instant shutdown. So i rebooted again and shut down like normal.


Today, I booted up, jumped into Tarkov and was able to get into the hideout multiple times with 0 issues. Ran a few raids and hit the hideout each time with no issues.
So I decided to try the OC scan again, and it completed as expected and gave me a suggested oc +200mem +114gpu. So I set it and ran the OC again. Passed with no issues.

From there, I set the power target to 80% and ran a few raids. No issues at all. But I only played for about 2 hours.

So I am concerned and kinda stumped.
I am not sure now if I should be looking into a new PSU with a higher power rating or what.

So now here I am asking the masses. What do you guys think of my situation?

I was having the same issue with an EVGA 750w GA Gold. Sudden shutdowns. I bought today a NZXT C850 Gold, no a single issue since I put it on my build. There's another thread with people reporting what PSU are working and which doesnt.

 
 
Here is an update for everyone, and hope it helps.  
I ended up replacing my original PSU with a Corsair RM 850x and so far I have not run into any more issues.  It's only been two days but I have had no crashes since switching.

I’m having issues as well. Kept crashing in games and wondering what was going on. DDU, etc didn’t help. If I run OC scanner my pc just shuts off and reboots.

3080ftw ultra and an 850W GA. Apparently I bought the wrong psu. Literally bout it a month ago planning for the 3080. So frustrated. Can’t return it now either. So what, I’m out all the money because it can’t handle the wattage it’s rated for and need to buy a new PSU?

If you guys still saying this is related to PSU, that means you have to work around 3000 cards. So, all those reputable brands PSU's were and are really useless. I don't believe this is much related to PSU and If you get new PSU that supposedly will work, I'm wondering how long will take before you will be dealing with something else.
 
All this is hit and miss lucky if you get OK card otherwise blame something else like PSU
 

I did. I kept thinking something was up with my PSU and this thread made me feel more confident. Haven’t heard back yet so will see what happens.

Maybe it’s not the PSU and it’s the card, although there is another thread here somewhere and OP had same issue. EVGA told him this GA psu and some combinations, ie 10900k cause power draw issues. Which sounds like they are aware and won’t fix. They basically said, “it’s a GA which is an entry level psu”. Not cool.

Could be the card. But this is at least the second thread with same issue using same GA power supplies. That and considering my entire pc ****s down and reboots as soon as it starts raising power/voltage during an OC Scan, and crashing flouring my games I feel it’s safe to assume it’s the psu

NO....
 
Just certain models of PSUs are having issues...
 
There is a thread with a list of known working PSUs.
 
https://forums.evga.com/W...-WORKING-m3118557.aspx
 
The EVGA GA is one of the models that do not work, can't handle the transient power spikes.
 
The PSU is much more important than people think, getting a high quality one is important.
 
I tested my 3080 FTW3 Ultra with 4 different PSUs myself.... 4 of them and they all work fine, no shutdowns.
 
HX 850W, HXI 850W, Prime Ultra Ti 750W, and AXI 1600W

Try to get an upgrade from EVGA (pay the difference).  850w G3 or better.  Avoid the G5 series.

Looks like they discontinued the G2, that was a huge mistake. Rock solid platform too..
 
Was one of the best Gold Rated PSUs on the market, actually better than the G3.
