I recently built a new PC featuring a 5070Ti GPU, 9800AXD processor, an X870 motherboard, and an 850W power supply unit. However, I've encountered a troubling issue: just a month after my purchase, my GPU began to black out randomly, even when it was idle, and would emit a loud noise. After bringing it into the store, they diagnosed a failure during the OCCT test and replaced it with a new one that passed testing at the store.
Unfortunately, that replacement GPU also started failing after just a week. Here are some key points:
* Under heavy load, the system runs smoothly but then suddenly disconnects with a loud noise. My monitor connected directly to the motherboard continues to work, so I can restart without trouble.
* There are no spikes in HWMonitor before a blackout, and the software continues to run.
* The event log shows no errors.
* The new GPU also fails the OCCT test, although it passed at the store.
* I've connected my PC to a UPS.
* Lower resolutions don't help; the OCCT fails without any error message.
It seems unlikely that I would receive two faulty GPUs with identical issues. Does anyone have suggestions or insights into what might be wrong? Thanks for your help!

It sounds like your PSU might be the culprit here. Even if it's a brand like Inwin and has the 80 PLUS Gold rating, there's a chance it could still be causing issues. Power supplies can develop faults that aren't immediately obvious. You might want to consider testing with a different, higher-rated brand or a more reputable model.
I'd check the specific model of your 5070Ti and see if others have reported similar problems. Some batches could have defects that aren't fixed even in replacements. Also, try running a few different stress tests beyond OCCT to see if you can replicate the problem more completely.
Thanks for the tip! I’ll look into other users' experiences and try additional tests to better diagnose the issue.
That makes sense! If the PSU isn't consistently delivering power, it could definitely mess with the GPUs. Maybe I should swap it out as a next step.
