power use

If I keep the distance between each strip to around 3cm the light is pretty diffused on the acrylic when they're placed 2cm away (thickness of the steel frame). Each LED needs 60mA, which totals to 6.24A with 8 strips on the bottom plate. I think if the distance from the tank is more than 2cm (around 5-6) i could decrase the amount LEDs by alot.

The motors need a running current of 900mA and a start current at 2.5A. So i need at least 7.2A / 20A to power 8 servos.

The micro control unit needs at maximum 800mA.

So in total i will need at least 27.24A to power all the lights, servos and the MCU which is a lot of current (this can't be right can it?). In this case I think i should seperate the ligts from the servos / MCU so that maybe i could use one 5V 15A for the servos and one 5V 10A for the lights? Alternatively power the lights with something like this instead?

A standard computer power cord is usually rated for 15A so i could maybe use one for each PSU? Then find the correct AWG size cable to wire from the PSU up to the servos. I feel like my calculations here are way wayyy off. Can a wall socket even supply this much since i need double to power both objects?
