Upd - Adp-200er Schematic

: The unit is rated to provide 12V DC at approximately 16 Amperes .

A metal oxide varistor (MOV) protects against over-voltage spikes, while a ceramic fuse (typically 4A/250V) acts as a sacrificial barrier against over-current conditions.

Conclusion

The large primary bulk capacitor can hold up to 400V DC long after the power supply is unplugged. Always use a dedicated discharge tool or resistor to safely bleed off this energy before touching the board.

If the console clicks on for one second, flashes a blue light, and immediately cuts power, the PSU protection circuits are triggering.
