A few weeks back I built a new Centos 7 server from a 4 year old workstation PC, and a brand new HDD.
This PC had no prior problems other than it ran Windows 7. Thew new HDD is because I'm planning to also use it as a Bacula storage device.
For the moment is purely an AirPrint server, using CUPS and Avahi so is ide 99.9% of the time.
My priblem is that twice now it has turned itself off, the last time being at 7:40am today. There is nothing I can find in the logs prior to it going off, just the normal start-up entries when it's turned back on.
Can anyone suggest why i may be happening, or how I can diagnose it. The server is in a UPS protected cabinet in locked room

First thing I would do is check the temperature. In my experience, excessive heat is the main reason for unexpected shutdown operations.
I'm using the nifty Glances utility (available in EPEL) to do basic monitoring. If your server overheats, you'll gradually see your temperature indicator turn from green to purple and then to red. I know there are other utilities, but this is good for checking this sort of stuff in real-time.
Cheers,
Niki

I have had this in the past where either the CPU or PSU fan had died. I'll check both of these next time I'm on site, but I believe the PSU is fairly new anyway.

I installed Glance and had a look, but the sensors didn't show, even when I pressed 'S' as per the help page.
Also, as this is a headless server, can anyone suggest a non-GUI monitor app?

The lm_sensors package is required for the sensors module of glances to work. After installing lm_sensors, run sensors-detect. The sensors command will show the sensors detected and their current values. glances should then display the sensor readings.

Somewhere tucked in the back of my mind a memory is screaming no. Wasn't there a problem with lm_sensors where we were all told to remove / not install it because of serious problems with the package possibly even breaking things.
Presumably that's no longer the case

If there was such a problem it is very far in the past or it only shows up on hardware I don't have. I have never had any problems with the lm_sensors package breaking things and I have been using it for years.

Glances *is* a non-GUI app.
The banner of my blog is a screenshot of Glances in a terminal:

If the PC turns off and stays off it could be a power supply issue
If you cannot put the old disk back, try to use another power connector for the hard disk
