You might want to start grabbing system info to see what's going on prior
to the shutdowns.

I have a script called sys_stats.sh you could look at. I haven't in a long
time, so it might be out of date...

https://www.LuftHans.com/unix/

My script doesn't capture temperature info. gkrellm will do that for you.
I think it has a 'save the info' option.

I believe there's a debian package that has tools for stuff like my
sys_stats script. Probably better than my script, but I didn't see the
package with a quick search.

Turn up the syslog output and capture at the lowest level, debug.

Is there anything else plugged in to that UPS?

When plugged in to the wall was the UPS unplugged?

Causes I can think of:

not enough juice ( the 500 W power supply should take care of that )
overheating ( the extra fans should help, but maybe cpu fan is on funny )
buggy mboard or ram ( install one of the memtest packages and test )
buggy UPS
someone keeps rebooting it ( leave the keyboard there, but unattached )

The last one should be causing syslog output.
