Player > Starships > Power Core
If I don't have to have enough PCU to power everything on a starship at once, when do I decide what to power?
Outside of combat, you can choose to change what systems are powered freely. However, you have to decide what exactly is powered on your ship as combat begins and you can't change it during combat, as it requires too much fiddling with wires, switches, programs, and such.
The power core is the most important system on a ship, as it provides power to every other system. The table below lists the ship size each core is designed for, as well as the PCU it provides and its cost. Each Large and smaller ship has room for only a single power core by default, but Medium and Large starships can be fitted with an extra power core housing (see Expansion Bays on page 298). Huge starships can have up to two power cores, Gargantuan starships can have up to three, and Colossal starships can have up to four. Though some ships are exceptions to this standard, they are rare in design. A power core typically has a backup battery system for use in emergencies that can provide limited power—enough for life support, gravity, and comms (see page 430), but no other systems—for 2d6 days.

Supercolossal ships have massive power needs. They also have enormous space dedicated to power systems, allowing them to use power cores that won’t fit in other vessels. A Supercolossal ship can mount one of the power cores of Supercolossal size shown in the following table. If a Supercolossal starship has a Supercolossal power core, the vessel can have up to four backup cores; those cores must be designed for Huge or Gargantuan starships. If a Supercolossal starship does not have a Supercolossal power core, the vessel can instead mount up to five power cores designed for Colossal ships.
