Hi there, I would guess that trying a new power supply is a sensible first step. They are the most frequent failure point and a power outage is often the point where they no longer get to their feet because of the startup stress that they haven't had in a long time of constantly being powered. However, I cannot guarantee you that this is all you need to do. If the SB3 still fails with the new PSU, it's likely that the situation is similar inside it, i.e. capacitors needed for a clean startup and to filter ripple are no longer able to do their job and cause the system to be unstable or even unable to boot at all. Replacement of the internal SMD capacitors is my step #2 in this situation usually. I hate to give you more worries but eventually it could be CPU death which is not recoverable no matter what. All we can do is hope that it's only one or both of the other two options mentioned. Let me know if you need more detail or advice. If you are inside EU, you might consider sending me the unit to Germany for a full diagnosis (free of charge). I'm in good training regarding the replacement of SMD capacitors and testing power supplies. I could not cure CPU death but a lot of other issues.
