ASRock B650E Riptide - Kernel Power ID 41 - New

Hi Folks,
I build myself a new gaming pc with the following specs:

- ASRock B650E PG Riptide WiFi ATX AM5 AMD B65
- AMD Ryzen 5 7600X - 4.7 GHz   
- Enermax LiqMax III ELC-LMT360-W-ARGB (wei?)
- CORSAIR Venge. DDR5 32GB kit 6000MHz CL36
- PowerColor Radeon RX 7900 XT - 20 GB
- fanxiang S880 2TB PCIe 4.0 NVMe SSD M.2 2280
- be quiet! Pure Power 12 M - ATX 3.0 - 850W
- CableMod PRO Series ModMesh - White
- Montech SKY TWO, Midi-Tower - wei?

Now, the problem is that my PC sometimes reboots out of nowhere. It sometimes happens on the desktop whilst doing nothing but surfing, and it mostly happens in Apex Legends.
The LOG tells me kernel power ID 41 has happened.

- I have already tested my ram with 1 stick at a time, still reboots at some point.
- I have tried stresstesting wit AIDA and other benchmarks.
- My pc won?™t reach windows/reboots if I fixate my ram to the 6000mhz, or try setting different PBO settings.
- No BSOD

And the weird thing is, I can have a session for 8 hours and nothing happens, and now yesterday it happened 2 times within 2 hours - it does not feel like it happens more frequently, and I can?™t force it.

The PC runs very well, super smooth - but I am so lost to what I could be. My Guts tells me it?™s the motherboard ?˜¢?˜¢?˜¢

Thanks in advance!
