So my last print job just finished without incident, not even the 99% completion bug. I decided to open the power supply and I confirmed that the enclosed unit was identical to

So I decided to order this one that has 30 more watts of rated power:

It will be here Monday and I will report if there are any issues but I don’t expect any as it is a an exact physical replacement from what I can see. It is also only $28 shipped. I know it is only 30 more watts but that may be difference between a failure once in a while and a failure never which will be worth it.
One thing I don’t like about the power supply design is that the fan for the enclosed unit is covered and seems to try and flow the air from the front of the unit into the PS and then out the back. I wonder how effective it is and also the fan is loud so I wonder if the way that the unit is designed is amplifying the noise. I would think about a new case that holds a larger silent computer fan to blow air into the unit to reduce noise and improve the effectiveness of the cooling.
I also exported the logs and could not see any indication of an issue. I found the section of the log where the incident occurred and did any see any magic message:

I can include the entire log if requested but it showed nothing interesting in that section. I am looking at the rest of the logs for how it behaves in a power outage recovery mode versus what happened here…
