The picture up above is not the project, but a thought about what it might look like. The power supply has an input of 12vdc and 1.5 amps to 10 amps in. The power supply has 2 spst relays, 1PC fan, 1 fuse, 5 LEDs (2 internal green LEDs for a glowing feature, one red external LED that is hooked up to an external battery that tells you that there is no power whatsoever, one yellow LED that is to the right of the red LED that tells you that there is power availuable, but not on, and, lastly, a green LED that tells you that the power is on. The last three LEDs that were explained, only one can be on at a time. That is why there are two spst relays). The power supply unit also has two voltage dividers with individual heat sinks for each one, a power supply module (MB102), resistors for the LEDs, and the original power supply unit case. The power output is 12vdc, 9vdc, 5vdc, 3.3vdc, and a USB port.
The Schematic is in the Gallery because since I have a Chromebook, Circuit Maker doesn't work so instead, I used EasyEDA.
The printed cricuit board design is in the Gallery also.
The printed cricuit board picture designs are also in the Gallery now. I will soon buy the PCB and build the power supply unit and see if it works good.
