Got home from work today and my wife mentioned that the server was off and she had to turn it on, but it never fully came online. It was stuck on a 04 code on my ASUS Pro WS WRX80E-SAGE SE WIFI II. This is a “PCH initialization before microcode loading” step for that board. 
 

I had to turn it off, unplug the power cable, and hold down the power button for a while to drain residual power, but it worked and the server came online like nothing ever happened (besides a parity check due to an unclean shutdown). Not sure where to start on the troubleshooting side of things. I have a decent amount of drives, but my power supply is 1300W and I don’t think those would be maxing it out (just replaced two drives that had smart errors which are connected in unassigned disks so I can run extended smart tests on them). 
 

With those two new drives, I added an LSI-9300 8i HBA with the stock cables. 
 

Any ideas or help would be great!

Server shutting down by itself is almost always a hardware issue, unless something/someone initiated a shutdown, enable the syslog server and post that if it happens again.
