PSU OCP? Or GPU Issues?

CPU: Ryzen 9 3900X
AIO: NZXT Kraken Z73
GPU: PNY GeForce RTX 3080 10GB XLR8 Gaming EPIC-X RGB Triple Fan
MB: ASUS TUF Gaming X570 Plus WIFI
RAM: G. Skill Ripjaws 32GB 3600mhz CL16
PSU: EVGA SuperNova G3 1000W

I have been having this issue with my PC for the past 5 days. The PC turns off and the power button becomes unresponsive until I flip the PSU switch. This looks like an OCP issue and has happened to me before with the same build on an EVGA SuperNova GA 850W unit. My current PSU was working fine for the 6 months I have had it with no problems. Now the PC turns off while idle and with load. I could be typing an essay or playing a game and the PC turns off. I have tried to undervolt my GPU and reducing its power limit to 70%. I also ran both Heaven, Furmark, and OCCT. I have also ran memtest86 and my ram came back with no errors. I am on the latest NVIDIA drivers, BIOS, CPU Chipset drivers, and Windows 10 version. No matter what I do the PC turns off and I have to reset the PSU. I also checked to see if any of the cables were loose and everything was connected properly. I am currently thinking of upgrading to an ASUS Thor 1200W PSU or a BeQuiet! Dark Pro Power 1200W PSU.

So this issue has occured on two separate PSU units? Any OC your CPU or GPU? Are you using a UPS? Can you swap out the GPU for another unit?
 
Do ASUS boards still have their voltage/protection systems? If yes, have they improved them? I remember seeing stuff like this way back with ASUS boards.

I bought the board back in September 2020. No clue if they still do I might have to RMA the board as an incase if anything as well

Yes, this occurred on 2 different PSUs. I don't have an UPS. Both CPU and GPU are running stock. The only other GPU I can test with is a 1060 but I do not think that will cause the spike but will try

Yes but your spiking at idle and running MS Word, what is the RTX 3080 pulling in those scenarios 10-20w? I think you need to test every PC part even something as simple as the PSU cord if you are re-using the same one. How old is the electrical wiring in your home? Any thunder storms in your area just before the issue re-started?

No thunder storms in the area for a while, and the wiring I am not sure how old it is. Do you think my surge protector could have too much plugged in? It has 2 monitors, an amp for my headphones, some rgb lights, and 2 logitech speakers. The odd thing is that I am spiking at idle because on the old PSU it would only be on games. I just turned on my PC and simply opening event viewer made it turn off.
 
Probably the PSU, again, need another one to test though. The fact you're having to reset OCP with switch is telling.

I've also had very similar issue with an EVGA SuperNova PSU before.
 
I am planning on testing a 2070 on my current setup to see if that trips the PSU
 
Have a look at the event viewer, big red X entries, also look at a couple entries before those happen. If it really is a PSU issue you will have kernal power faults, mostly error 41.
 
Can you test your gpu in a known good rig?
Being that youve gone through two power supplies already makes it unlikely to be a power supply issue. The odds of your getting two bad units in a row are highly unlikely. Especially if they are exhibiting the exact same symptoms. Rather it sounds like a mb or gpu issue. The next time it happens try clearing the cmos, or pulling the battery vs flipping the psu switch.

I did have an event viewer critical error 41. Which again makes me suspect the PSU is failing me

I will test it on my friends rig who basically has the same build besides having a 2070.
 
That's also normal for CPU core temps exceeding the limit set by AMD, IIRC.
 
If you google around, you'll find quite a few instances of EVGA SuperNOVA PSUs having these kinds of problems. Be interested to see a TPU review teardown of the newest EVGA SuperNova range, not sure who manufacturer actually is? Mine only lasted a few days. Tripped out first during Firestrike ultra, then would randomly shut off regardless of PC load, with OCP reset via switch needed, got RMA'd.

Might not be the problem here of course. See how you get on with the 2070 in anyway.

Would love to see a teardown as well. Hopefully EVGA respond to my rma request as I think switching out the PSU is a smart idea regardless due to the amount of issues that have been reported with it and a 3080 combo.
 
Hello, trying to build new PC with RTX 3080 Founder's Edition and also saw that it is possible to have issues with some PSU (power supply unit) when it turn off when using with RTX 3080 (OCP - over current protection probably).

Owners of RTX 3080 please write the exact model of PSU you are using with RTX 3080 without any problems/issues. It will help me a lot. Thanks to all who will decide to answer.
