I had the random reboot issue awhile ago too with my 5 year old EVGA 850W G2. Ironically, it happened mostly on idle or very light workloads (youtube and twitch). After trying several things with no solution, I end up letting a friend borrow the card and he ran it fine for a week. I contact EVGA customer service and got a replacement PSU and it has been 3 days since I replaced the PSU. So far so good but I will continue to monitor it until the end of the week to ensure stability. 
 
So for those who has those random reboots issue, my guess would to first put your gpu into known working system to make sure its not the GPU, follow by contacting your PSU manufacturer to send you a replacement.

 EVGA or Nvidia has no control over what the PSU manufactures do or don't do or how they design their units.


 
There are tiers of PSUs based on cost and quality just like everything else in the world today.
 
So just saying a X wattage PSU is recommended doesn't mean anything, it's the actual model of the PSU that matters. EVGA and all others sell total crap PSUs as well as good and then excellent ones as well.
 
There is a lot more to a PSU than just the wattage, efficiency rating or brand name. 

I have an EVGA 3090 FTW3 on the way. What else should I consider on PSU choice other than wattage and efficiency rating. I feel like I haven't been thorough enough with my research if there's a lot more to it than just those things.

 
Get a HIGH QUALITY PSU, 850W or 1000W or higher if you want more room.
 
A few examples:
 
Corsair RMX 850 or HX(i) 850
 
EVGA P2 or T2 850

I would just like to add, I have a rmx 850 2018 ver. And my 3090 red lighted during, I think blaming the psu might not be the play.

In the same Boat:
 
EVGA 3090 FT3 Ultra
Motherboard ASUS ROG Strix Z490-E 
CPU Intel Core i7-10700K 
Memory Ripjaws V Series 32GB DDR4 3600MHz CL16 Dual Channel Kit (4 x 16GB)
Heatsink Corsair iCUE H115i RGB PRO XT
PSU: EVGA SuperNOVA 1000 G5, 80 Plus Gold 1000W
 
Updated Bios
Crashes in Chrome watching YouTube and in some games. But mainly Chrome
Screen goes black; PC does a post beep; hangs. Then either sits till I reboot; or it boots into the bios.
 
Event log throws the following error most of the time.
BugcheckCode 278 
 
PSU has 4 ports for PCIe power. 
I'm using ports 1-3, each on its own cable.
 
Updated bios, Windows, ran DDU
Turned off OC switch on card
Updated the OC bios on card
 
can't think of anything else. 
 
Oddly it seems more stable running benchmarks then watching YouTube.
 
Any known issues with the PSU: EVGA SuperNOVA 1000 G5, 80 Plus Gold 1000W PSU?
 
I can attach any logs needed; Just let me know what log and how to get it :D
 
Do you think it could be the power cable to my UPS from the PC, was too lazy to swap it out with the new 100W psu cable ? Seems unlikely tho. 

Already been said, but its definitely a PSU capacity issue.

I just buit my new system and waiting for the EVGA 3080 FTW3, noticed this issues and just wanted to clarify if I will have the same problem with my Seasonic GX 750W? The list says it's ok, just want to be on the safe side. Thanks.

Seasonic GX750 or the old version?

I am not overclocking my CPU  and my Seasonic focus gold 750 psu is shutting down on a basic power test with the FTW ULTRA 3080.

I really don't think it's his power supply specifically. I have a seasonic 750w which is a quality brand but it's also shutting down. It's evident that a 750w PSU isn't enough for both the 9900k and 3080.

Certain PSU models can't handle the transient power spikes of the 3080's and 3090's.
 
Even some 850W units are shutting down....
 
We know the EVGA GA and some Seasonic Primes and Focus also shut down.
 
The ones we know work are, so far:
 
EVGA G2, P2, T2;
 
Corsair RMX, RMI, HX, and HXI.
 
 

Corsair AX not on he list?

Hello everybody,
 
I have question regarding my PSU.
I read that many of you had issues with RTX 3080 and Seasonic Focus 750w Gold.
Unfortunately I have same PSU and now I'm worried because of shutdowns you were mentioning.
My PSU is about 6 months old and I'm afraid that it may shutdown my PC while playing very graphics intense games.
Here are my full PC specs:
Desktop:
OS:Windows 10 x64

-------------------------------------------------------
PSU:Seasonic FOCUS 750 Gold
-------------------------------------------------------
Case:SilentiumPC Signum SG7V EVO TG ARGB
-------------------------------------------------------
 
 
I have connected my PSU with my RTX 3080 via 2x PCIE cables,but I was thinking if ordering another third party/universal PCIE cable would help?
That way I would have 3x separate PCIE cables in my GPU (I'm not sure if universal PCIE cable would work although being universal).
 
Also,I haven't been playing anything yet,but I ran OCCT stress test for PSU for 5 hours SSE and it passed.

What model of GPU do you have RTX 3080 or 3090?
Did you play any games with it for more than 4 hours and what stress tests did you do?

I have an Seasonic GX 750W, 2 Month old....it works with the FTW3 so far 2 Direct 8pin+1 in daisychain. I'm still stress testing the GPU to see if I will have some problem, so far it's good.

I will definitely notify you here if I encounter any problem.
I was thinking of underclocking too,but I don't know how many FPS would I lose in games like Cyberpunk 2077.
I don't have discord unfortunately :/ but I will report any issues here ASAP.
I have Evga RTX 3080 XC3 Ultra Gaming.I still haven't play any games,but I heard people had problems with graphically demanding games like Borderlands 3,so I'm going to test it with it in next few hours.I'll get back with results once I'm finished.

I have 3080, I played for about 5-6hours for now..Call of duty MW. I used 3DMARK Extreme test and Unigine. Can you please notify me here on this forum if you will have any problems? I'm thinking also to underclock at least 50hz Boost, cause the Cards pulls about 380W.
You can add me on discord, so we can discuss it further.

I have the 3090 FTW3 Ultra paired with a EVGA 850W GA.
 
I have not experienced any shutdowns or restarts. I have not updated my bios to anything but enabled to OC switch. I've done some overclocking with a stable 120+ Core / 1000+ Mem. Highest I've seen was 453W.
 
Even with that, no issues have yet been discovered. I'll let you folks know when it does happen.

What CPU are you running?  I had no issues with my i7 6700k but ran into shutdown issues once I upgraded to the Ryzen 9 5900x. 

I have a Corsair RM1000X. I get shutdowns (and eventual restarts) unless I downclock the card slightly. My system usage during gaming minus the GPU is around 200-250 watts. While it COULD be a bad PSU, I'm wondering if something else is up here with so many people having issues. The voltages for all my connectors are in spec.
 
Looking at that graph in a previous post, it looks like the GPU has spikes that can exceed 600 watts. I am wondering if maybe there is a peak above that for certain cards. In my case, it sounds like a PSU auto shutoff trigger. I've been trying to get some solid logging going on, but with the system shutting down so abruptly it makes it impossible to see what the total power draw is when the shutdown happens.

I have a 6 or 7 year old 750W G2. No card yet since I have no luck at queues, but hopefully I don't run into the issues you guys are having.

I had a 6 month old AG750w Gold and it wasn't enough, but now way to know until you try it

I overclocked the 3900x and the 3090 Hybrid XC3, and when I started to play Cyberpunk, shutdown! I dialed back the overclocks and it works fine now. The 750W PSU just isn't enough. Its only a year old.
