Well ima try the evga 1000w titanium psu on Friday. If that doesn’t fix problem I’ll give the evga 1600w titanium one from micro center a shot. After that ima just rma the gpu, but im like 90% sure it’s the seasonic psu, and that they don’t require a flip switch.

 
It's a known working unit so you will be fine.

You just told me it’s not my psu though? Now I’m even more confused. My pc instant restarts. No windows “restarting” and it only happens when I increase power limit to max on afterburner/precision x1 30 series version. Something is triggering some instant hardware turn off (or I guess by your definition HARD restart). I guess you are saying that it’s the gpu and psu? I’m so lost.

 
What I ment was that PSU, the 1000W TI is fine.
 
And that was all.

I have the same issue with my 3080 FTW3 Ultra as well. Running on an EVGA Supernova G2 850W that supposedly "high quality." I have been using this PSU for 5 years with my 6700K and 980ti and it was fine until now. GPU ran at stock speed and cpu has a slight OC at 4.5ghz while memory is running its default XMP profile. 
 
Been dealing with restarts for about 2 weeks randomly. Most of the time, its under light load (youtube, twitch)...that's the sad part. Under stress test - no reboots. When gaming, it happened once... I believe Windows Event Viewer says that I have about 9 reboots in the past 14 days. I tried re-seating the cables, running it on stock, running an undervolt..and etc. Even monitored the 12V rail with HWinfo64 (fluctuating between 12.192 and 12.096V under load and a constant 12.228 idle).
 
Next stop is to try another replacement PSU. I am contacting customer support for this. Based on Nvidia's recommendation, the FE card is running at 320W and requires a 750W psu. By that logic/ratio …the FTW3 ultra card which runs at 380W - 405W (for me), would need around 900W to 967W PSU. But then again, a lot of people are running their 3080 fine on 750W and 850W. Well, done ranting...will continue to troubleshoot and good luck to everyone in the thread.
 
 

I might be mistaking, but I read somewhere here on this forum, unless I'm confusing with different model that EVGA G2 has issues with these cards

Ya I thought of G2 been like one model..DD tbh. I don't even know what PSUs EVAG makes I only heard G2 so I assumed

It's the GA that's the real issue for the EVGA PSUs.
 
The G2 was one of the best PSUs on the market before they stopped selling them.
 
 

Well unfortunately for me that's not the case. Maybe 5 years of use took its toll on the PSU.. I am hoping it is the PSU and not that actual GPU ...but at this point who knows? . Only way to find out is if I get another PSU to check. Hoping EVGA would cross-ship me a replacement to check.  FYI..the error i get is the typical kernel power 41 error - "sudden lost of power". This system been stable for 5 years until the gpu upgrade.

Kernel 41 could be a number of things, but it is normally related to the PSU or the MB.
 
See what EVGA can do for you.

 
Yep, thats why I am hoping its the PSU. I would assume everyone else who ran into this reboot problem would have the same error in event viewer. I've been troubleshooting with EVGA for about a week. Do you think this has anything to do with the x16 PCI-E slot? I did notice that my pcie slot no longer "clicks" in like it used to..maybe the retention clip at the end wore out but that shouldnt affect the card too much as long as it seated properly in.

i have a 
EVGA 220-G5-0750-X1 Super Nova 750 G5, 80 Plus Gold 750W

Are those ok?

Honestly, not too sure. There are no reviews on that PSU in particular so its hard to say. Some people have success with 750W and some don't. Some have success with 850W and some don't. I'd say u run it first for a few weeks. If you don't run into any problem such as the computer powering off/rebooting then you should be fine. This card alone draws about 380W to 400W which is over half of your psu capacity itself. You may have to undervolt it to lower the power consumption. I have a friend running a 3090 undervolted on his 650W just fine.  It was originally drawing 360W for him, and undervolting it reduce consumption by about 100W.

I'm just curious, why people undervolting their cards?

I cant speak for everyone, but generally it is to maintain the highest stable clock speed with the lowest amount of voltage. Typically, when you first put load (aka doing anything graphic intensive such as playing games, video rendering etc) on the card, your card will initially run at say 1995 MHz. Your core voltage will jump up and down automatically from say .800V to 1.062V base on the load condition to make sure that the card is stable and does not crash. Higher the voltage = higher thermals. Higher thermals = thermal throttling = your core clock not being able to maintain the 1995 mhz and automatically downclocking itself to say 1935 to maintain good thermals. So people who undervolt would rather have a stable clock at a constant 1900 mhz at significantly less power consumption and minimal performance loss versus having the gpu fluctuate its clock from 1995 mhz back and forth to 1875 mhz all the time. 
 
Also, for the 3080 since there is no real overclocking headroom, therefore increasing power consumption for a 5% boost is kind of pointless unless you are chasing a top 10 overclocking score on 3Dmark. Dropping the voltage down to around .825 will reduce your power consumption from 360 to 220W ish for minimal performance loss. You could watch some guides of how to do so if you are interested.

Very good explanation, thank you sir.

I also am having this issue with this card.
My system:
Intel i9-9900k@3.6GHz, RTX 3080 FTW3 ULTRA 10G-P5-3897-KR, 32 GB [16 GB x2] DDR4-3200 Memory Module - GSKILL Ripjaws V, GIGABYTE Z390 AORUS ULTRA, Thermaltake Toughpower Grand RGB 850W 80 PLUS Gold, Full Modular
I am monitoring gpu temps with Precision 1 and cpu temps with MSI Afterburner and have no high temps while gaming, but having repeatable reboot occurrences while gaming.
No overclock of CPU or GPU.
Should I RMA the card or is a fix coming?
I have even changed my Windows 10 power option from high performance to balanced and it does not help.  

Seasonic is sending me a Prime TX-850 as replacement. I will report back to see if this fixes anything.
 
So far my findings have been pretty consistant: the shutting down --- restarting only seems to happen in heavy ray-tracing games with power slider going over anything above 101%. It is definitely power related.

Will have to provide power supply model number tonight from home, but I am being advised by Thermaltake tech support that since I was previously running a RTX 2080ti with no problems and the only thing that has changed is the new RTX 3080 GPU, it is related to the card and I should RMA. I am able to put my 2080ti back in and it runs fine.

The 2080Ti is not a 3080.

3090 gobbles up way more power than 2080Ti ever will.
 
Sounds like lazy customer service to me from Thermaltake. Seasonic acknowledged this problem immediately after I submitted RMA inquiry.

I did look into the EVGA power supply power meter questionnaire.
Upon completion, it recommends a 650 watt max. power supply.
I have 850 watts, so I am thinking I have ample power.

3090 and 3080 have power spikes in the duration of milliseconds and THAT can be really high. See Igor's lab's review here
 


 
 
Mind you that is only the GPU. Plug in your CPU and other components, you are looking at a huge spike of power draw. Although most PSU can handle AVERAGE rated power draws, those huge spikes tend to trigger the PSU's surge protection. Which is exactly what is causing all these problems.
 
Older power supply and some newer PSU are simply not built to handle these short spikes.
 
 
Quoting igor himself:
 
Peaks with intervals between 1 and 10 ms can lead to shutdowns in very fast reacting protective circuits (OPP, OCP), especially in multi-rail power supplies, although the average power consumption is still within the standard. For this card, I would therefore calculate at least 460 to 500 watts as a proportion of the total secondary power consumption of the system with a normal OC with up to 400 watts as the power limit as the graphics card load, in order to have enough reserves for the worst case scenario. A short excerpt with higher resolution shows us now the 20 ms measurements (10 μS intervals), as I let them run automatically for value determination:
