I had a spare 450w no name brand ATX PSU, so I turned it into a Bench PSU for projects.
It is a standard setup with non variable outputs for 12v, 5.5v and 3.3v

Removing the PSU board from its original enclosure is extremely dangerous. Becareful please.

I have included a Fusion360 file, you can edit the mount posts on the panel to fit your own PSU board if it differs from my design.

The switch hole on the fan panel was made to fit the standard mains switch found on most entry level ATX power supplies.

Below are links to all the components used:

Opening a power-supply is dangerous. Even if the power supply is off and unplugged there is still a very good chance that the capacitors have a very high charge stored in them.

By modifying, removing the PSU board from its original enclousre or using my designed enclosure is done so at your own risk.

If you are not sure on how to handle the psu board safely, please do a little research first for your own safety.
