Question Need to replace failed psu- recommendations b/c not sure is 12VO

[kslibra]

I believe my psu has failed because it started making a noise, then a waivery sound, and now it doesn't seem to have enough power to stay started or power the monitor.

Acer Predator P03-600UR18, using Liteon 500w DC5001B004

I've been told on the Acer community forum that I have 12VO but it seems to me that I do have a 24pin connection to my mobo.

I've images from the manual* and would like to know if a "normal" psu will work or if I have to pay double for the Liteon psu THX!

* How do I post them???
