A server at my business went down at 00h28, no load shedding.

The server is a Dell Optiplex 7040, one of those mini pc thingy majigs... Windows 7, 8GB ram, 128GB standard M.2 drive, external power adapter connecting it to a UPS.

I checked the power brick and cable and it's working 100%. The pc is dead, won't boot, CPU fan doesn't spin, no chirps from the mobo, no post to bios, nothing!! DEAD!! DEAD!! DEAD!!

Changed the CMOS battery, no difference.

What happened to it?

To add insult to injury the hardrive appears to be faulty too, no retrievable data, 'needs to be formatted before it can be used' error message, not picking it up, tried connecting to it in an external M.2 drive caddy, tried installing it on another machine, don't see the drive in the bios, nothing, nixs, dololo...

WTF has happened?!!
 
I'm so disappointed. This machine has run flawlessly for the best part of 4 years...
 
I reckon the psu shat itself and toasted the drive.

Also, windows 7, no sympathy here

Not sure if the drive is toasted if it can now be formatted?
But definitely PSU related in my opinion

Power brick of the fong kong variety I assume?
 
PSU might have had a bipolar incident and provided too much power at a few seconds

With those really cheap Chinese power bricks f#@king anything is possible.
Don't get it twisted, Meanwell a Chinese company makes EXCELLENT power bricks (can't recommend it enough), so it isn't Chinese made that is the problem.
It is the power brick that is impossible cheap and unknown/throw away brand.
