Hello all,
 
First time posting even though I've signed up as a member here in 2010!  I putting together my first build. I've always had a friend help me before but I wanted to do it myself this time. I tried to find a thread in the forum about the same issue I have but I couldn't find it. 

Here's my build:
3900x wraith air cooler
MSI x570 tomahawk wifi
32 gb gskill trident neo
EVGA RTX 3080 ftw3 Ultra
EVGA 850 G5
be quiet 500 DX. 5 fans. 3 intake 2 exhaust.
Mushkin 2TB nvme m.2
 
Test Bench. I wanted to see if it post and check components. Everything was found (I think) but got "Device changed (cpu or memory) or cmos have been cleared." I figured it should run since this MB should have the bios to run a 3900x. I looked it up, and it was something about the MB battery. I didn't think it was because this is a new board. I can't remember if I pressed F1 to run setup or F2 to default. It might have been F1. But I pressed "Delete" after that or restarted and It went to bios. Everything was good and kept it running to read up on what to do next for Windows install. About 10-15mins after starting, Long Beep and I smell burning. MB VGA led debug light was on. The GPU fans were not running. I remember the 3080 fans and led did turn on at the start, but it stopped. I quickly turned it off. The card was hot and smell burnt. I thought it might need the GPU drivers updated after Windows and drivers installed and updated. I let it cool down for ~30 mins. Started it up and was successful installing Windows. I was about to do the updates when the Long beep went off again. I went to windows shutdown.
 
The switch on the EVGA 3080 is set on Normal, not OC. I did check that. It has 4 old capacitors and two new ones (from the YouTube videos I saw. This was an issue of overheating with 6 old capacitors).

The GPU fans should run even on the test bench Right? Or at least turn on when it gets hot. I didn't touch any settings in my MSI bios. The MSI MB doesn't have the same codes as my old z170 EVGA board for my 6700k. Just led debug lights.

I did submit the same question to support. I think I may have to RMA. I have registered this Card. 

Thoughts?

On the Normal VBIOS switch, the fans don't turn on until the GPU core hits 60C.

On the OC VBIOS switch, the fans run at a minimum of 33% all the time.

Quick note - you have to restart the PC for the GPU to load the new VBIOS, or switch it when the PC is off.

You might want to install a GPU temperature monitor program of some kind (Precision X1, Afterburner, etc.) And check out what the GPU temp is. Also, a program to monitor the CPU temps.

Edit: you might also want to double check that any cables aren't laying over high temperature components.

Edit2: if your motherboard loses settings after being off and unplugged, the CR2032 (CMOS) battery is the likely culprit. They have been known to be dead/dying even with brand new boards - a bad battery batch, or the board sat for a couple years and the battery slowly drained.

I will try switching it to OC VBIOS while it's off and see how that works. I was planning on loading MSI Afterburner and GPU-Z as I have them on my old computer. 

I think I will change the battery since that was the first issue I came across when I first started it. 

All of my cables are nicely tucked under. They are not touching any hot components. Thanks!


 

I finally figured out the problem. The Long beep sound was from my Backup Battery/Surge Protector. Lack of power caused 99% of the issues. 
 
I did change the CR2032 battery on the MB because of the first issue I had. Better safe than sorry and I think it helped, and I switched my GPU's VBIOS to OC keeping the fans running at 33% constantly. Thanks Arestavo! I wanted to time how long it takes for the beep to occur. 5 mins in long beep and then it turned off! So, that was a good sign. I decided to try updating Windows until the long beep goes on again thinking it was an overheating problem (sort of). And loading up the drivers could clear up the issue. First round of Windows update needed a restart. After screen goes dark thinking it was ready to boot again, the Long beep sound, and the computer never restarted again. Crap! WTH happened? The Long beep sound is still on but the power to the pc is off! I unplugged it. Still on! It was weird. So I decided to check online what could be the issue with my old computer. Then I realized it was Shut down as well! LOL  I looked at my Battery/Surge protector and pressed the reset button. It turned off the Long Beep. I plugged my new PC into a Surge slot, not the battery side. Turned everything on and problem solved! Dude, I was laughing so hard in Relief! 

But looking back when I first put everything together on the Test Bench, the overheating of the GPU was because it wasn't getting enough power. Lack of Power from the wall, not the PSU. I have 3 outlets to my Battery side: my old computer, monitor, and plug the New computer. I never had an MSI MB before. So after 15 mins on the test bench and a long beep sound turned on, I thought it was the MB sound and the VGA led debug light was on. The old computer has a Z170 mb and it has debugging codes and beeping sounds. Apparently MSI MB's don't have beeping sounds (that I know of). It could have been the PSU. I have heard of stories with people's 3090 GPU's. Their EVGA 850 psu wasn't enough. 

I did get to run Heaven Benchmark 4.0. 
But on Ultra settings
FPS: 310.8
Score: 7829
min fps: 43.8
max fps: 526.6

What size UPS do you have? I would suggest ensuring you have one that is 1.25x the size of your PSU, don't plug anything else in the battery side, and if you can, get a Pure Sine one, not a simulated sine.  It should help performance a bit and reduce "noise" from the dirty wall power. 

The noise you're referring to, is that why the PSU is making a humming sound? I never heard of using a UPS. I'm checking out a Pure Sine. Thanks!
