It really should. Are you actually having things shutting down when you deploy weapons or are you just hearing the "power capacity exceeded" message? If the latter then it's normal. If the former then there's something strange going on as that loadout should be fine.
No it's not shutting down,(did did the first time but I dropped the life support down to the C, was B) so just the message, I was trying to figure out, why there was a difference in what is displayed, vs the actual usage.
