Each power has a manifestation time, which specifies whether the manifester must use an action, a reaction, minutes, or even hours to manifest the power. Manifesting a power is therefore not necessarily an action, but most powers have a manifestation time of 1 action.
Any effect that ends as the result of casting a spell, such as the invisibility or sanctuary spells, also ends if you manifest a power in the same way. If you wear armor you lack proficiency with, you can't manifest powers because the armor's bulk is a mental distraction.
Psionics are powers of the mind. As such, any effect that affects a creature's mind to prevent that creature from taking the Cast a Spell action also prevents them from taking the Manifest a Power action. This includes effects such as the barbarian's Rage feature and the feeblemind spell. The GM has the final say in which specific effects prevent a talent from manifesting a power.
