Default [CX450] Power up prevention after failure?

Hello people.

I would like to know if the Corsair PSU's (including the CX450) have some sort of "smart protection" that prevents the computer from being turned on right after an unexpected shutdown or a power outage.

I'm asking that because sometimes my PC just does not power on by pressing the power button. When it happens, the workaround is: remove the ATX cable from the MOBO; make a jumper between the PSU_ON and GND pins; connect back the ATX molex connector; press the power on. After that, I'm able to use the computer perfectly.

I noticed that it happens when I forget to shut down the line filter while I'm not using the computer (e.g. overnight). As lately there have been some power outages in the neighbourhood, I'm wondering if it could be related...

PS - The other option I'm considering is that my MOBO (Gigabyte B450M Gaming) might be defective and it is intermittently failing to start up the PSU. Could it be possible? Even knowing that, once powered on, the computer works perfectly?

Thank you.

My regards.

(edited to correct misspelling)
