Specs:
- CPU: Ryzen 5600x
- GPU: 6800 XT
- RAM: 2x16 (32GB) Trident Z 3600mhz CL16
- PSU: Hummer 650W
- Motherboard: Gigabyte B550 Gaming X V2
- SSD: WD 850X (2TB)
- SSD: WD 770 (512GB)
- Monitor: LG27 1440p

Steps done so far:
- Disabled PBO (Stutters with or without PBO)
- Turned on SAM (Stutters both off and on)
- Freensync Premium with Enhanced V-Sync and Frame limiter in RTSS (Helped to stabilize the problem)
- Gamebar disabled
- Used a Windows 11 Debloater (didn't notice any real difference)
- Windows updated
- BIOS updated to the latest version
- Chipset updated to the latest version
- GPU updated to the latest version

Games tested:
- Cyberpunk (microstutters every 10-15 seconds)
- Rainbow Six Siege (macro stutters)
- Warzone 2.0 (micro stutters)
- Hogwarts Legacy (micro stutters)
- Diablo 4 (micro stutters)
- Call of Duty Modern Warfare (no stutters)

Context:

1 month ago I upgraded the monitor (from 1080p to 1440p), upgraded the RAMS from 16GB to 32GB (new set of RAMS), and bought a new SSD (850X). After that upgrade, I tested a few games and everything seemed fine (at least I didn't notice any stutters). In the meantime, I bought 2 new exit fans for my case and a new cooler (arctic freezer 34 eSports edition) because my Ryzen 5600x was hitting 95º degrees in games and after that, I started to notice stuttering in games. I'm not sure if the micro stuttering was already there but I have never really noticed it.
Using Afterburner I didn't notice any weird behavior besides frame time spikes (7-8ms spike to 30-40ms out of the blue when the micro stuttering happens), temps seem to be fine, and the clocks don't drop when the frame time spikes happen, so I don't really know what's the issue.
Not sure what the problem is or how to fix it.

Note1) As far as I could tell, the frame time spikes happens with a low fps drop (sometimes it only drops 5 or 6 fps, and the frame time spikes to 40ms). Both GPU and CPU usage seem to be stable but the power draw drops slightly when the frame time spikes happen. Didn't notice any other weird behavior.

---------

Note:

  • No micro stuttering before the upgrade - 16GB RAM, 1080P monitor and SSD (WD 770)
  • No micro stuttering (as far as I noticed) with first upgrade - WD 850X 2TB, 1440p monitor and 32GB Ram
  • Micro stutters started after second 'upgrade'- 2 extra case fans and 1 new cooler for the CPU

You have more than the one issue going on there but the above is of the most concern;

There is one thing that is possibly worse than using a known poor quality brand of PSU and that is using one that is unheard of, for brands of PSU to trust and brands to avoid please refer to the links in my sig, brand names differ but AMD state here a minimum of a 750W PSU is required, not just any old PSU will do either, high end GPUs need a high end PSU such as the Corsair RM range.

It's a sub-division from NOX. It was highly rated when I bought it back then and never had an issue with it so far.
I used it in 3 different rigs with no issues whatsoever and never had any issues with this PSU with this GPU.

What other issues did you detect?
 
Can I ask that you do not quote every reply as we have to read the full post to make sure nothing gets missed,, thanks.

Who are so bad that even their Gold efficiency rated PSUs only had a two year warranty and I say " had " because they are obsolete and so obscure in fact that they do not even get a mention on the PSU Tier List.

See those links in my signature, they are a good indicator that I know what I am talking about when it comes to PSUs and Nox had so little trust in their PSUs that they only gave them a measly two year warranty, your build needs a PSU with a minimum of a seven but preferably a ten year warranty.

I used it in 3 different rights with no issues whatsoever and never had any issue with this PSU with this GPU.

No idea what you mean by the above.

!00% cast iron facts here, the PSU is crap and even it were a good brand it cannot provide the minimum output that your GPU requires.

Short version, the PSU is killing your hardware and the GPU being the most power hungry will suffer first and the most, you should also be aware that you have voided any GPU warranty by not using an appropriate PSU.

What other issues did you detect?

Nothing that will kill your hardware if you don't correct it and no point in wasting time on a system that could go bang at any time.
