Support the power supply with one hand if it could fall while removing the last
screw. (Such as in a tower style case.) Remove the power supply by sliding it back
and then out through the side of your case.
8. Install your new power supply by positioning it through the side or top of your case
(depending on your case style) and then back onto the power supply mounts. Check
that the orientation with the screw holes in your case is correct; all four holes must be
aligned. Support the power supply with one hand while threading a mounting screw
through the back of the case and into the power supply. The screw should thread
smoothly and should not require effort. Do not force it or you could damage the
mounting holes. If the screw won’t thread smoothly, remove it and check to ensure the
mounting holes are correctly lined up. Repeat for the remaining three screws. Do not
fully tighten any of the screws until they all have been threaded into their mounting
holes. (Note: Consider Startech part SCREWTHUMB screws for easier installation.)
