After starting by mounting the power supply, I actually noticed a problem with the two negative voltages of -12V and -5V. 

Both of these power supplies have a small design error. Nothing very bad but this implies on the one hand not to mount the two regulators concerned, as can be seen on the previous picture, and on the other hand to make the corrections to the printed circuit board.

This considered, nothing prevents continuing to build what will ultimately only be a prototype since a final version involves making corrections :


Nice board however!
