Does the PD board Output 12v Stable?

No, he means the regulated 12V output can only support up to 20 watts; which is enough for the wireless bridge. The other power distribution outputs are limited by the circuit breakers (20, 30, 40 Amps.)

Errr... How is the regulated power supply relevant?

You wanted a clean 12V supply for your custom electrics. The only clean 12V supply is provided by the regulated 12V output for the wireless bridge. Eric mentioned that for your application the regulated 12V supply does not offer the 90 Watts you need; only 20 Watts, and it's also by rule exclusively for the wireless bridge.

In the end, if you want a regulated (clean) 12V supply you will have to provide it yourself by attaching to the unregulated outputs (the ones with circuit breakers you add in yourself.)

The question was meant to address how regular the power was when taken from the unregulated outputs - I'm not planning to plug the wireless bridge into the unregulated power supply, even if it's regulated power would have supplied a high enough wattage to power the motherboard. The main point of the question was to determine how variable the current/voltage was when taken directly from the unregulated supply. Thx everyone for fully answering the question

If the voltage vs time graph were a road, and you were to drive on it, you would lose your lunch. It is a very dirty, very bouncy thing.
