Question Faulty PSU?

[K3nt14]

Hi guys
I have a seasonic SII-550W 80+bronze(2021), about 3 months ago it started to do random reboots, in event viewer showing kernel power 41. I switched the PSU from another pc, everything works fine with xmp on/off, but if i run xmp on my psu the reboot comes back. Initially i thought it was a ram problem, ran memtest 86 and i found out that one of my ram sticks were bad, but even so the reboots continue with the xmp on/off, the moment i set the ram at 3000mhz it restarts, but if i let the ram run an maybe 2933 or base speed 2133 everythings alright. I think the problem here is the psu, i don't think its the ram
What do you guys think?

41 will pop up for any unexpected shutdown, not just bad PSU.

Does Event Viewer show any other event ID? I would expect to see some things coming up for that issue with higher RAM speed.

What are the complete specs of this system?

If this is a Ryzen system 2933 has history of being more stable than 3000.

So the complete specs are this way
Amd Ryzen 5 3600-3.6ghz
1650 4gb
16gb ram ddr4 3000 (8gb at 3000 atm)
One m2 and one sata(both kingston)
The event viewer doesn t show any other error, but i think its the power supply because when i moved my psu to the other pc, the other pc had the same problem

Since i got the pc i ran it at 3000 mhz until i found it my old cpu(Ryzen 5 2400G) didn t support 3000(not a big difference but still). It ran this way until i change my cpu. In july i didn t open the pc for like 2 weeks cause i was gone and when I came back the problems slowly appearing. I didn't had performance issues with the problems, just restarts, crashes and bsod(bsod showed corrupted files and that's when i suspected something was really wrong)
