yup 2a power (always an A class.. the class determines heat efficiency, Size the amount of power.
Then put the biggest fsd and power distro on it , distro for fast boosting, especially from pirates
Make everything else D class to shave off weight for that extra jump range, ditch the docking comp and scanner and get 8 tons more space,and ditch the weps for more range imo.A cmdr will kill it in seconds so not worth fighting, and u can submit, boost and fsd from an Npc easy.
If u insist on the weps and dock pc, set ur cargo hatch to a low priority as u will be slightly over power when u deploy, (2%) and that hatch is 6% power draw u dont need.
Edit, at the bottom of the shipyard look at the % thats power use, the top on is with hardpoints retracted, the second is with them deployed, untick boxes next to items that arnt needed ( E.G cargo hatch is not needed in combat) to simulate disabled modules (u can turn them off in the right panel, or set a lower priority ( ironically a higher number is a lower priority,so dont get confused) for unneeded modules n the right panel as well
So to show u, check my vulture, its set for both use in a RES and a CZ, u will see with hard points out its draws 111% power

now for a Cg i dont need a kws, rather i want more sheilds so i manualy disable the KWS ( go ahead , un tick it now) so now its only 109%... but i also dont need my cargo hatch,fuelscoop or FSD during combat in a CG(switch them off to now), now u can see im at 100% (tbh if im jumping into a CG, i will turn off my cargo,scoop,kws manualy before i enter, and set my fsd to lowest prioity (just remember if u need to bail out of the zone fast to close the hardpoints asap, it takes about 7 seconds for the fsd to come back online

))
Now for normal bounty hunting, i dont really need both sheild boosters running,but i want my KWS, so turn off one of the boosters, and the cargo hatch, and reactivate the rest and u will see yet again im at 100%.
Hope that helps explain a bit for you
