Powering my mirror?

That should be enough for all if you don’t have more than the LCD, Raspberry Pi and the step-down module. You should check the power consumption of the LED strips, if you’re planning to use some. If not, you should be good with 30W.

@MadScientist
Will both the LCD and the step down wire to the same wire? Will this lower the 12 volts from the lcd? -
You split the 12V output of your power supply. One set of wires (plus and Gnd) goes to your LCD controller board (check polarity!) and one set to your step-down-converter, which is regulated to 5.1V for the Pi.
-
My point is that all the power supply’s under 80W only have one set of output wires.
-
Just use luster terminals.
-
@MadScientist sorry for so many questions. But won’t I need to solder them in a “T”? Or get a T splice?
-
Don’t be afraid to ask…
Pic says more than a thousand words…
You can solder the wires together but that’s not really needed.
-
@MadScientist ok awesome! That really did help I wasn’t thinking of doubling them up in the terminal.

This converter isn’t adjustable and it’s only 5.0 v would this work? -

should do. They are adjustable via a potentiometer. Iam using the latter one for a Pi Zero but the 3A are enough to power a Pi3 easily. You should check aliexpress.com since most of the low priced parts already come from China. They will be even cheaper and are the very same product.
