so its "ok" to over power fit a ship? ive been avoiding it cos i did it once and everything shut down and scared me! I guess I can de-prioritise like you say the FSD and Docking Computer and keep the combat stuff liike you say. Thanks for the advice
Yep, it's a bit more advanced but common enough on certain ships that are a bit underpowered. When you think about it, it makes perfect sense to divert power from things like your cargo hatch to your weapons during combat, it's just more efficient. However, you'll want to trial-and-error your setup before going into heavy combat, and remember that if someone shoots out your power plant, you can have even less power available sometimes. Everyone/every ship will be different, but here's an example of how you might set up your priorities:
1. ESSENTIALS - thrusters, maybe FSD
2. WEAPONS - lasers, cannons, etc.
3. DEFENSE - shield generator, cell banks (I also put life support in here)
4. NON ESSENTIAL MISC - warrant scanner, power distributor, etc.
5. NON COMBAT - Fuel scoop, cargo hatch, etc.
Some people put their FSD lower down their list, but I prefer to keep it online at all times so I can escape if need be. I have mine set up so that when I deploy, anything set to level 5 will power off. Then, if things go wrong, 4 will be turned off and if things go really bad, 3 will be turned off. When 3 goes off, life support goes off, so that tells me when it's time to get the heck out of the situation. Reason being, if your level 3 gets shut off, that means they've already gotten through your shields.
But each to their own, like most things in the game, there's a lot of different "right" ways to set up power!
