Could under-rated wires inside the case be contributing to the low power as well?

I don't know, can you connect the power supply without those cables and test it like this?

On a side note. do you know of a good place to get a 3.5mm to RCA Composite AV Cable that works with the RP3?

Alas, I don't know that either, because I didn't need such a cable in my household, yet. The value of such tips also depend very much on where you live. I live in Germany; since it's 9 a.m. here and you posted about 5 hours before me, I doubt that you do, too. ;)
