Automatically turn on homelab after power restoration

[sakibsadmanshajib]

I have a home lab which I use to test software, host websites, docker containers, and serve media files using Jellyfin. It's an old gaming rig with the following specs:

CPU: Core i7 6800K
Motherboard: MSI X99A Godlike Gaming
RAM: 16 GB DDR4 2666 MHz (2* 8)
GPU: GT 710
PSU: Thermaltake TR2 S Series 550W

I am running Ubuntu server OS.

During the summer season, I am facing some extended power outages every few days in the week. I want to make sure that my server automatically turns on after power is restored. I was thinking of building an electrical module with a relay switch and connecting it to the power supply and the power switch pin in the motherboard. But I am not an electric engineer, so I am not sure if this will work. I am asking if anyone has a solution using off-the-shelf components first. If not I would love to get some directions on how to build the module.

N.B.: I do have an 2000VA offline UPS, it can't provide enough backup.

Most BIOSes have a feature to turn on after power loss, wander around the bios before dumping money into this problem.

^^^ Came to say exactly this, you should be able to set it to auto-power on again after power loss, costs $0 cash and... maybe some in time, depends how stupidly or not your BIOS is layed out and what your time is worth. 

 

Also, is the computer just cutting off when the battery on the UPS runs out?

I found the BIOS settings for it. I feel so stupid to not look through the BIOS before seeking some hardware solution. Thank you the issue is solved.
