Editing Atari Falcon Capacitor Replacement Guide (section)

== PSU Capacitor List ==

The Falcon PSU is a switch-mode design providing +5V and +12V rails. The following capacitor list is based on the standard Falcon/STe PSU.<ref>{{cite web |url=https://www.atari-forum.com/viewtopic.php?t=31402 |title=FS: Capacitor replacement kits for Falcon030 motherboard and PSU – PSU list |publisher=Atari Forum |access-date=2026-03-27}}</ref>

=== Safety Warning ===

The PSU contains a high-voltage (400V) capacitor on the primary side. '''This capacitor can store a lethal charge.''' Disconnect from mains, wait at least 5 minutes, and verify the capacitor has discharged to under 1V before working on the PSU.

=== Notes on PSU Capacitors ===

* The replacement values are intentionally higher than the originals. This is standard practice for PSU recap — larger capacitance provides improved filtering and longer service life.
* The 400V primary-side capacitor is the largest and most dangerous component. Use a 105°C rated snap-in type.
* The total cost for a complete PSU capacitor set is approximately €7 (2018 prices).
* It is also recommended to replace the bridge rectifier while the PSU is disassembled. Upgrading from a 1A to a 2A type (e.g., replacing with a higher-rated unit) provides additional margin.
