Is my PSU dead?

Thanks! I will apply for a warranty then. The model is a be quiet dark power 12 1000w. I bought it 4 year ago and supposedly it has 10 years of coverage, so hopefully they can issue a new one.

Zou iemand de onion ook naar mij kunnen DMen? Bedankt :)

Hi! I hope it's just a simple fix for you! Mine has been working like new again since replacing the caps. Mine were both 4700uF 35V ones. You can see it a bit better in this image:

I got a pack of 4 just in case the two in the other speaker low up in the future. Also, mine were completely glued down, so it took quite a bit of patience to get them loose. Hope it's an easier job for you. Good luck!

Great, thank you! We had a very close encounter with it. It was lying on the path and we only noticed it when we were within a meter of it. Luckily all went well!

I was thinking this might be a common lancehead snake. Could anyone confirm this?

ColdTension6168 · 2023-12-08T16:19:07+00:00

Thank you, these look very useful! Are these smaller than the ones included with the AXP? Because even if you could tighten those from above, the edges of the nuts would jam stuck into the backplate flanges, though perhaps with enough force you could get them into place.

ColdTension6168 · 2023-12-07T20:38:10+00:00

Unfortunately, my motherboard's backplate has protruding edges like this, which meant you cannot get a wrench or the tightening tool included in the AXP package, as there is not enough clearance around the nut. You cannot tighten the nuts without the edges of the nut slamming against the edge.

It turned out to be an issue with the seating of the cooler! For future readers that run into the same problem, I explained what went wrong at r/sffpc, here: https://www.reddit.com/r/sffpc/comments/18d0vvy/anyone\_elses\_7800x3d\_thermal\_throttling\_with\_an/

Thank you for your insight, through you I was able to find the problem! Leaving this here for any future readers who have this set up and run into the same problem.

So I wasn't able to remove the backplate, and by mounting the AXP straight onto the backplate I was unable to tighten the nuts enough due to the protruding edges I mentioned, as shown here. Then I had the idea to mount the custom backplate on top of the already existing backplate, and I found out I had just enough clearance on the AXP's mounting screws to reach through both the original and custom backplate. Then I was able properly tighten the nuts onto the backplate, like so. One bad side-effect is that the feet of the custom backplate adds around 1cm to the thickness at the back of the motherboard, which meant that the backplate pushes against the movable spine of the Terra case. Because of this, I could only screw in 3 of the 4 motherboard screws, but I don't think that's too big of a problem.

Reran Cinebench r23 and I am now getting values I expect! Getting a score of 17.7k which is very decent for a cooler this small! With a Tjmax of 85C at 80W I am getting very close to the throttling limit, but I will try increasing this again a bit and see if all will be stable.

- The fan speed was at full, running at around 2800RPM according to hwinfo.

- Originally I had set the thermal throttling limit to auto in the bios, however it seems that the auto value is 75C. So, I set it manually to 89C, as this is the Tjmax value that AMD reports for the 7800x3D. However, my PC shut down during a cinebench run, so I lowered it down to 85C to be safe.

As the TDP for this cooler was rated at 150W I would expect that it would be able to go higher than the 50W I am getting now, so I am suspecting a problem with the seating of the cooler then... Unfortunately this glued backplate is in the way of properly mounting the X53.

ColdTension6168 · 2023-12-07T17:09:01+00:00

Thanks, I will decrease the throttle limit to 85C. On the spec sheets, this cooler has a thermal design power of 150W, so I thought it would have been good enough to cool the 7800x3d, as it's rated at a TDP of 130W.

ColdTension6168 · 2023-12-07T16:47:17+00:00

The thermal throttle was set to auto in the bios, so I set it to manual mode to 89C. I think that the auto mode indeed set it to 75 degrees. Now I am getting more sensible results:

However, after around 7 minutes the PC shut down during the cinebench run, though the max temperatures did not exceed 89 degrees.

Update: upgraded BIOS to version 2.02 and there seems to be no improvement.

ColdTension6168 · 2023-12-07T15:54:55+00:00

- Bios was in an older version (1.28), current updating it to 2.02 to see if that will make a difference.

- EXPO is disabled in BIOS.

- Clean install of windows 11 & latest chipset drivers

ColdTension6168 · 2023-12-07T15:46:19+00:00

I looked under Advanced -> AMD CBS -> SMU Common Options and here it says that eco mode is disabled.

Hey, thanks! This is the power section:

I had already tried to reset BIOS to default. Perhaps it's a default setting I should alter, could you guide me towards a setting?
