Hello, I just bought a 750 watt power supply for my 2012 dell optiplex 790. The only problem is that I can't get it inside the computer because this clip for the side panel is in the way. Can somebody help me remove it?
Are you sure this is a clip for the side panel? Seems like it too far to be something related to the side panel. It's like 2 inches from the side by judging where it is placed behind your PSU. Looks to me like a stop so you don't change the PSU yourself and make your life miserable.
Is the new PSU physically a larger dimension than the stock one? That would have been a good thing to check before buying. I guess you could break it off, but then you'd have problems with the side of your case. Maybe shave a few mm if just just that close?
