The rapid clicking thing is the give away. Especially with your partially recapped psu.

It's the caps on the output side of the psu.
Basically the psu is starting up, but then when the full load is applied it shuts down, then starts up, and shuts down etc etc

Each time it starts up it energises the relay, and each time it shuts down it releases the relay, which is the clicking you're hearing.

Do the full recap and your problem will vanish.
