CPU: 6700k @ 4.5 GHz
Mobo: Asrock Z170 Extreme7+
PSU: Seasonic Snow Silent Platinum Rated 1050w (5 years old)
 
Installed the 3090 with no issues. It was replacing my FTW3 1080 ti.
 
Card was mounted in the top x16 slot, and case was open to keep an eye on things because I'm paranoid whenever I install new hardware (heh...) So plenty of breathing room for it. Ambient temp in my room was like 72 F / 22 C. 
 
Updated to latest Nvidia drivers, installed Precision X1 and updated the firmware when prompted to. Changed the RGB color but didn't touch OCing or fan control. 3090 was idling around 30 C.
 
Ran a few games and tried rendering some stuff in Adobe Premiere. No issues and performance seemed great. Highest temp I saw was 63 C.
 
I'd had the card in for all of 4 hours at that point. I was idling on the desktop while chatting to a friend on Discord when suddenly... The screen went black, I heard the fans on the 3090 ramp up to jet engine mode, and I could faintly smell burnt plastic/electronics. Quickly powered the PC down and gave it a few minutes to cool off.
 
Powered back up and the card had a single red light with no RGB.
 
I was able to get into bios and windows using my 2nd monitor plugged into my mobo using the igpu. The 3090 wasn't recognized at all. Tried running DDU and reseating the card. No dice. Flipped the OC bios switch while powered down. Nothing.
 
So my brand new, $1800, not even out of the box for 24 hours GPU is a brick. I reinstalled my 1080ti and it's working just fine.
 
I called tech support last night and the guy I spoke to was great. Started the RMA process, went with the standard option so I just gotta ship my card back to get the replacement. Hopefully it was just a random lemon from the bunch and not indicative of a larger issue with FTW3s. But there's been several other threads, and this guy's video which all pretty much describe the same issues: (edit- can't post links?) youtube dot com watch?v=qUVdJxdqUNY
 
I'm also skimming these other threads talking about certain PSUs not being able to handle the 3090's transient power spikes. My PSU is a bit older now (Seasonic Snow Silent 1050w) but it's got more than enough wattage, and Seasonic isn't known for being crap... And never had an issue when my 1080ti was installed. So people saying "x PSU (doesn't) work with a 3090" seems like pretty worthless data, unless they've personally tested multiple PSUs with the same card.

Are you using custom power cables, or the cables that came with the PSU?

All 3 cables came with the PSU.

dang, sorry to see your card has failed
 
Did you run it at all before installing the X1 software ? 
 
X1 updates the MCU -- have to wonder if that is related to the failure, though we really wont know unless EVGA releases information about cards that fail

Starting to see a pattern here, imagine the amount of Dead cards we don't hear about, because the user is not on the forums.

There is a pattern - older power supplies, power supplies that are known to have problems with the 30 series, or newer power supplies that don't have those issues but they used custom cabling.
 
Now, that's not the case for every one that has problems - but a good portion of them (about half from my own tally).

so, how do you explain the custom cables not killing the users old card?

450W card vs 250/280W cards.

Then again, I've spoke to Seasonic yesterday and explanation on cabling with new or older cards and he said.. Unless custom cables weren't created with org. PSU specs that might be a problem and that would pretty much apply to 24pin as some PSUs have monitoring and dynamic voltage adjustment, other then that  that really wont make a difference

Wire gauge thickness makes a difference if power draw is higher over the same cable. It will heat up the cable a lot more - which is where I surmise the problem is coming from for custom cables that are thinner than the original PSU manufacturer's cables.
 
However, I'm not an electrical engineer - just an old school ground radio repair dude with a passion for computer hardware.

Have to be very careful when getting a custom cable kit, make sure they actually do meet the specs of the OEM cables that came with the PSU. I am talking about wire gauge here and the pin outs match.
 
Not even going to go into extensions, not a good idea for a lot of reasons, best to get the replacement kit.

How old is that PSU?

How old is that PSU?

5 years.

OK, that's the older model.
 
Might want to upgrade to a newer model and it is getting close to end of warranty, 7 year warranty.

Welp. Looks like I'm gonna buy a new PSU just to be safe. 
 
I'm actually gearing up for a 5950x build. Was hoping my Seasonic would last through multiple builds, but better safe than sorry.

 
The one you have now has a 7 year warranty so not not really as they need to be replaced once they get close.
 
The new Primes for example have 12 Year warranties so yeah, that's different.
 
 

Oh boy now this is getting even more concerning as I await my opportunity to order a 3090 FTW3 Ultra...

This is a proof that one big batch of 3090 FTW3's are all faulty. They need to figure out from SN and send a warning.

Man this is getting concerning. My Seasonic is 7 years old and I am hoping to pair a 3070 with it. Hope such problems do not come to the 3070 being a low wattage card
