Dell Optiplex SFF power supply to ATX adapter

Adapter plate for mounting a power supply from an SFF Optiplex into an ATX case.

Printing

Printed in PLA with 4 outer walls and 20% infill. The power supply can sag a little with these settings (see image), so higher infill is advised when mounting the PSU in the top of the case.

Mounting

4x 6-32 screws (standard ATX PSU screws) screw directly into the adapter plate and the Dell PSU screws can be reused to mount the PSU to the plate. Note that you need ~23 cm of clearance to fit the PSU in your case.
