Question Crash/Freeze problem with RTX 3080Ti... maybe?

[Dweagar]

Installed an ASUS ROG STRIX RTX 3080Ti a couple months ago, ever since, been having random freezes/crashes. This only happens in a game, never while doing anything else. When it freezes, I have to power off the computer and power it back on. After the post-freeze power cycle, the computer operates normally.
PSU is sufficient to support the GPU.
Power is stable (new home, stable breaker, surge and power protected)
Card runs under load well below max temp (typically around 50c)

CPU: i7-8700k
RAM: 32gb
PSU: 750w

What make and model is the psu? There are 750w PSU’s that are adequate but there are some that are a hazard.

Are you using a pcie riser cable?
Are you using extension cables for gpu power?

Some RTX 3080 cards cause even good PSU's overcurrent protection to kick in due do very high transient power spikes.
Do you have Afterburner installed? You could try lowering the power limit a bit.

My GPU power is as low as I can set it, GPU target temp as low as it goes. I've left GPU voltage at defaults to reduce the odds of creating instability.

You really need to answer the power supply question.

Which question was that? You asked if I used Afterburner.. I use ASUS GPU Tweak II, which does everything Afterburner does.

But if it were a PSU issue, why does the issue not manifest after a post-crash power cycle?

 

[John Chesterfield]

You were asked earlier in the thread in the very first response which exact power supply because 750w might be cutting it fine with the card you have.

This is a relevant question, especially if you have an EVGA power supply or some cheapo thing.

If you can provide that answer, great. Google 30 series transient power spikes and you'll realise why you're being asked this question.

In that regard, it is highly likely that this is a "cheapo" PSU. It was a best buy purchase under a cyberpowerpc brand name, I doubt they put that much thought and consideration into their PSU brands.

I actually pulled the PSU out and looked at it.. says its a 800W PSU made by "High Power" , which according to other posts on this website, is made by Sirtec.
I removed the card from my computer and replaced it back with my old 1080Ti to see if I get any of the original issues with the 3080Ti.. so far, its been stable.
