Hello!
I have a X470 GAMING PRO CARBON and bought an ASUS TUF 3090 OC and experiencing power downs (no reboots). For example at the beginning of a work unit of folding at home. Or when I set max settings in Metro 2033 Redux. I get a guaranteed power down.
I've already updated to the newest BIOS (AMI BIOS7B78v2I2022-08-05) and loaded default settings in the BIOS. Same story.

Then I checked the compatibility list and the 3090 is not in the list. Does that mean it is very likely that the board can't take this card?

Thanks in advance for any help!

Chris

Also turn off all that extraneous BS, Folding@home, whatever. Not worth it and constantly using and heating your GPU.

I would probably start with checking windows logs (aka event viewer) to see what the system shut down for, if it even shows anything.
Outside of that, it might just come down to a power issue.
How are you connecting all the power cables? Are they individual cables, or are you doubling up connectors on a single cable?
This GPU is known to take ALOT of power, and using a single cable to power 2 of the PCIe power inputs probably isn't going to end well.....

Hello!

Thanks for your reply, but how is turning off folding at home helping to find out what is going wrong? Isn't it an appropriate stress test?

Best regards,

Thanks for all you helpful replies so far. I'll try the event viewer. Maybe it is a software problem. The card is furthermore connected to two separate cables. I also try to get some spare parts to find out where the problem is.

Another thing of note: The "be quiet! STRAIGHT POWER 11 1200W Platinum", while being a very good PSU, is a multi-rail 12V design, with the four rails being split up into 24A, 24A, 38A, 38A respectively. So this might not be the ideal PSU choice for a 3090, which can have short peaks (called transients) of over 500W of power draw (source), that's >41A at 12V, which might be enough to trigger OCP in the PSU and cause a preventative shut-off.

From your RAM listing (grau), i know you're probably German (like me), so here's the important section from the source above:

If you want to try any spare parts, with a problem like yours, the only one that makes sense is a different PSU. Other than a graphics card that draws less power, of course.
Again, your PSU model is very good, but they really put the focus on the protection features by going with a multi-rail design, and a 3090 might be slightly too "triggering" already, therefore a PSU model with a powerful single-rail design might be better suited for that GPU. For example the "be quiet! Dark Power 12" can be switched to single-rail.

Thank you very much for the Igor's Lab info. I've read about these transients and also watched some videos since I started the post. I'll try the mentioned PSU and see if that helps and report back. Another one that seems to be recommended is the Corsair HX1200 (Gamer's Nexus).

Gamer's Nexus is extremely biased, and personally, the host is a moron.....

But I digress. The Corsair HX1200 is a pretty good supply, and should easily handle the system and that GPU, if I'm honest. Just keep it in single rail mode.
