ATTENTION: proceed very carefully during this step. Use reasonable force and don't rotate the printer. We need to adjust part of the frame, which might affect the overall geometry.
The new black PSU has mounting points in a different place, we need to rotate the short extrusion by 90 °.
⬢Start by releasing and removing M5 screws on both sides of this extrusion. Together you need to remove 8 screws. Note that four screws aren't visible in the picture (green arrows).

⬢Insert all eight screws back (from both sides), but first screw them in just slightly, stop about 1 mm from the surface.
⬢Remove the rubber foot by turning and pulling from the side and place it from the bottom, like the rest.
⬢Now, start tightening all the screws. ALWAYS tighten on a diagonal!
