Approach on LED stripe custom power supply

Hello Everyone ,

I'm starting with mounting LED lighting across my house. At the moment it all works well. The challenge I have is to make appropriate power supply.A one that is extensible with any extra connections I would like to make.

At the moment I got computer power supply that is capable of providing 12A nd 200W in total (of course it is much more than me or me and my neighbors need :smiley: ) , case for it , cables , fan etc.

What I seek is advice if design I have in mind for LED stripes (or any other 12V devices) is feasible.

My plan would be :

  1. to run cable from the lines that come out of the Power supply (PSU) into the PCB board and then to respective npn transistors and connectors. In order to use micro-controller to have control over the power
  2. Use banana plugs to connect devices to respective connections available on the box
  3. Maybe use ACS712 with LCD for current control.

Any design advice are much appreciated
