When did you contact seasonic?

if you're going with a ftw3, scraping by on your other components should not be an option. your PSU might not be handling it because you have no headroom for the sudden spikes you're likely encountering. whatever the minimum specs are, if you want to be safe you should AT LEAST go 100w over that...and that's just to get by with what you might have now. if you're likely to upgrade anything at all in the next year or so, you'll probably hit the wall again. unless CPUs all of a sudden stop using 200+ watts.

I'm trying to read up on the thread but wanted to add 2 cents.  My issue actually involves a 3080 FE rather than EVGA, but I'm spontaneously rebooting with a Seasonic 1000W Prime Ultra Titanium.  I feel like I should be good here but it reboots itself under load 1-2 times per day at stock speeds under load (Folding).  Underclocking/undervolting helps for sure but doesn't fix it.  Raising the power threshold reboots more frequently.
 
Nvidia has offered to replace the card and I was pointed here by enthusiasts so looking for data mostly.  I think the issue with transients is more general than a specific brand, obviously.
 
I reached out to Seasonic and awaiting response.

 
Yeah, rebooting is different than the PSU shutting down. I mean the PSUs literally shut off completely, the OCP kicks in and shut down the PSU so you would have to flip the PSU switch off then back on again. The Prime Ultras work fine with the 3080's etc.
 
Likely a card issue in your case.
 
 

Seasonic responded:
 
Your PSU is likely affected by our older models not doing well with high power graphics card's transient loads.
 
Yeah I have the SSR-850TD which seems to be affected.

Wow...kudos for Seasonic as that's the first response from a PSU maker/distributor that I've seen that specifically stated transient loads killing their older PSU's.  Linus also mentioned the transient spike issues briefly during his 3070 review and pointed at EVGA specifically.  I wonder if EVGA will release a statement...?

Yup... 
 
That's the Older Prime, non Ultra.
 
I still have an old Prime Ti SSR-650TD in one system, it will never see a 3000 series card so I am not worried.
 
The SSR-750TR works fine though, I tested it, that's the Prime Ultra Ti.
 
The new Prime TX's also work fine.
 
Seasonic will take care of you.

I hope. So far it looks like I will have to go on for several days without my PC. Their guideline says I need to mail the current one back to their NA HQ. They will have to test it somehow. They ship me either a repaired or replacement unit. I do wonder how they are going to repair it?

More like replace it...

Well I am hoping for the best, but given the current PSU shortage, yeah...

TLDR at the bottom.
 
Edit: When I says shutdown I mean the shutdown and reboot. Errors from the windows Event viewer.

Ok, I know a lot of people here are blaming your PSU. I also have not read through this whole thread, so maybe you have figure it out by now. I have also been getting random shut downs. I have only been getting while not gaming. I'm usually on reddit or something and then, bam, random shutdown. Only change to my system has been the upgrade to a EVGA RTX 3080 FTW3 Ultra.
 
My specs: 

• CPU: Intel Core i7-8700K
• Motherboard: ASUS ROG Maximus X Hero Intel Z370
• RAM: G.SKILL TridentZ Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3200 (PC4 25600) Intel Z370 Platform Desktop Memory Model F4-3200C16D-16GTZSK
• Storage 1: Samsung Evo 970 - 500gb
• Storage 2: Samsung Evo 850 - 2TB
• Storage 3: Micron - 2TB
• PSU: Corsair HX750i
• GPU: EVGA RTX 3080 FTW 3 Ultra 
• OS: Windows 10 - Build 2004 

 
I called EVGA support a few time while trying to figure out the issue. Their first assumption was I was not getting enough power and I should upgrade my PSU. I have a Corsair HX750i which you can check though the iCue software for output wattage. I was not hitting near 750W even under load. Anyways I found a Corsair HX1000i and placed an order it would take some time for it to arrive. In the mean time I tried the following:
 

• Update windows 10 to latest version
• Uninstalled then reinstalled Graphics drivers
• Tested RAM with MemTest86
• Cleared CMOS and updated BIOS
• Update Precision X1 from 1.1.0.9 to 1.1.0.11 (which did a firmware update of the GPU)

None of that worked. I got the 1000W PSU a few days ago and installed it right away. I fired up my system and a few mins after booting up I got a random shutdown... so it was not the PSU. I don't think it's your PSU. At this point I have an RMA in the works, but it has to be my GPU or Windows 10. I am not getting and BSOD or any other error messages. My guess is I got an unlucky GPU, but I have some time before the replacement GPU shows up I figured I would trying and find out if some software was causing the issue. I have been getting random shutdowns everyday all not under load (not a single shutdown while playing games). That is until yesterday. I normally keep Precision X1 running, but I exited the program after gaming yesterday and no shutdowns at all yesterday. As a test today I just finished up gaming with some friends and I left Precision X1 running. A few mins later random shutdown.
 
I think there might be a bug in with Precision X1. Again I am using version 1.1.0.11, but I experienced shutdowns using version 1.1.0.9. I suggest you try using your system without Precision X1 running and disable it from running on startup. 
 
TLDR: I think there might be a bug in with Precision X1. Try using your system without Precision X1 running and disable it from running on startup.
