I've printed and tested a version that has a thicker side bracket and where that side bracket is cut shot to remove the part bellow the first row of screws.
This version does not sag and works very well mechanically. Also the face of the screw holes is flat.
I am printing a new moded version whose top part ( the one with the two big holes ) is significantly shorter. It doesn't have to be that big I think. Will test it and comment.

- The original part you designed does not work well with pastic, as the vertice takes all the load and the piece starts bending outwards at the vertice.
- most of the side bracket can be removed as it does not play any mechanical function. All the mechanical load from holding the PSU straight is taken from the top screws up. So, from a space saving point of view, it can be removed.
- I also think the top bracket can be shortened alot. I am testing this.
- I still have no idea how the bracket secures to the case.
Hopefully you can redesign the bracket with these findings in mind.
