Nice, I received my 2nd PSU today, I’ll be swapping it over with the unit I have been testing so that I can return that to Overtek to have the proper fan screws fitted. When I get that back it will be getting installed into my friend’s desktop. I also bought a new case from Framework recently so I could get a new rear panel to replace the one I ‘modified’ when I first received the test unit.
As for the little bracket at the rear of the original PSU. I didn’t screw this onto the new PSU. I just screwed it to the case as the foam padding on the inside of it was holding the new PSU in position. I don’t think it would have moved in any case as it’s quite securely fixed by the screws at the rear of the case.
