Question PSU Energy starvation

[Rekyeme]

Hi everyone!
So, I'm having some issues with my machine and I have a feeling it has to do with the PSU. So, after some time playing Cyberpunk 2077 (around 1,5/2 hours)the pc just shuts off and reboots immediately. What I think that it is, is exactly what is written above in the tittle...But I'm not THAT deep into hardware to be 100% sure. To explain exactly what I mean by that I'll use cars as an example...More specific competition cars. Some of them have like 2 fuel tanks: the main one and a smaller one; If for some reason the fuel pump on the main tank is unable to pump fuel or there isn't enough fuel in it, the second tank will cover that problem until the main one can operate again. In this case since the PSU might not be able to "pump" enough energy it will starve for some milliseconds and come back again (since there is no secondary energy pool to take from) , causing the system to shutdown and reboot. I also had taken out the RAM and did all the proceedings I had to in case (I even re-installed Windows 11 two times thanks to this 🙁 ) I also searched the web and found 0 about this...
OBS: This might be me tripping very hard about a simple trouble with a simple solution, but I can't really find any other possibility for the issue.

PC Specs:
CPU: Intel I9 10900KF (Currently running at 8C/16T, if the problem persists I might reduce it to 6/12)
CPU Cooler: ThermalRight Assassin X120 Refined SE
Motherboard: Asus Prime H410M-K
RAM: 32GB 2666MHz
SSD: 1TB Crucial (SATA)
GPU: SPARKLE Intel® Arc™ A750 ORC OC Edition, 8GB GDDR6
PSU: Hummer Alpha 600W Bronze
Chassis: Idk, some generic thing
OS: Windows 11 Pro
Monitor: LG UltraGear 32GS60QC-B 31.5" LED VA QHD 180Hz FreeSync

that a low quality psu

and low quality motherboard to be using a 10900kf

Another explanation is your local AC mains supply might be prone to occasional short-term drop outs (too short to notice apart from a possible brief flicker of overhead lights in the same room).

If your Hummer PSU has a very short holdup time (it should be at least 17 milliseconds) and my theoretical AC mains glitches are longer, your motherboard will be starved of power and reboot.

To use your analogy of car fuel tanks, low cost PSUs "cheap out" on the main bulk electrolytic capacitor that store charge from the rectified mains supply. Too low a value and the hold up time is reduced down to 10 to 12ms. Really good (expensive) PSUs sometimes come with sufficiently large bulk capacitors to keep the PSU running for 25ms after the mains fails, well above the ATX spec of 17ms.

Personally, I'd fit a better quality PSU from a well-regarded manufacturer, e.g. Seasonic, Corsair.
