RX 590 not maxing out custom power limit

Hi, thank you everybody for reading. The short version of my problem is, that my graphics card doesn’t utilizes the maximum power limit if it is over the default power limit. In essence this is a refresh of an older topic of mine with additional trouble shooting. Power limit with CoreCtrl

So, i like to overclock. I use CoreCtrl to OC my Asus ROG Strix 590 8GB. This works fine to change voltages, clocks and fan curves. I also have the option enabled to modify the power limit, unfortunately changes to this parameter are not really applied by the card.
The default power limit is 185 Watt which responds to 175-180 Watt real world usage. If I lower the 185 to 165 for example, this change is accepted and power consumption will be capped. Any number greater than 185 has no impact.

I’ve confirmed that the value that CoreCtrl assigns is applied at the usual place. According to this Arch Wiki article, power1_cap holds the maximum value for power consumption. CoreCtrl does indeed change this value to the right amount as specified.
I’ve also checked if power profiles have any influence, but they don’t. I got the same results in the profiles 3D_FULL_SCREEN, VR and COMPUTE.

To see if this is a Manjaro specific issue i also tested this with a Kubuntu 21.10 Live System, using the Unigine Superposition benchmark as a means to max out power consumption. The behaviour is the same as with Manjaro.

For confirmation that this is not a hardware issue I tested the card with Windows. Using the official AMD tools I was able to raise the power limit and the card does indeed consume more power as monitored with RivaTuner and through actual performance. Temperatures are also well within specs, ranging from 65-80 °C.

I tried changing power1_cap_default but this action is not permitted.

I would be interested if anyone has experienced a similar problem to this, or maybe has a solution or another aspect to this. To me it seems like there’s a bug somewhere in the system, maybe the amdgpu driver. If so, where and how could i create a bug report for this? Searching for it didn’t give me some clear information to this.

Methodology:
For changes in power limit settings:
CoreCtrl, manually with

echo 227000000 > /sys/class/drm/card0/device/hwmon/hwmon2/power1_cap

To provoke power bottlenecking:
Cyberpunk 2077, The Witcher 3, Horizon - Zero Dawn, Unigine Superposition benchmark

Maximum OC settings are:
GPU 1590Mhz@1,15V
Memory 2000Mhz

Appended is an inxi output for my system.
Thank you all very much for your help.
