Hi. My mtboard: Aorus Z490 Pro Gaming
psu: Seasonic Tx-850 Prime Titanium


I went into the BIOS and changed the setting "AC BACK" to "always-on", which works when I plug the cables in and out, turn off the power via the PS button or when flipping my power strip switch. However, when there is a real power failure, the PC would not power itself back on until I physically push the power on button, I have tested this twice and got the same results.


I am not sure what is going on and how exactly can the motherboard distinguish between a power failure in my house and me just pulling the power cord, does anybody have any idea what is happening?
