I bought this PSU half a year ago even back then it was making a high pitched noise although I decided to ignore it. Now It's much worse, my PC turns off spontaneously every now and then most likely due to my PSU crapping out on me.
I boot my PC by holding the power button until the HDD starts spinning and then I have to wiggle the 24 pin connector a bit to get the other components to start up.
Once all the fans are spinning after multiple attempts I turn it off and wait until the high pitched noise goes away.
Then I promptly boot it up again hoping it will do the trick.
I hope I can fix it myself, since I bought the all components overseas from Newegg.
