ARC powered Power Supply Unit

For my projects I needed a power supply unit. There are lots of PSUs you can buy und even more models to DIY. But for me they are not fancy enough. They look so boring and they do not have feature overkill. So I designed a PSU myself. With these features:

- Direct connection to a wall outlet (220V or 110V)
- 2x USB QC3.0 ports
- 1x 12V / 3A port
- 1x adjustable port 0-32V
- Some fuses
- Active Cooling
- Fancy looks
- Lights inside
- STARK Industries logo
- Powered by an MK I ARC Reactor (...ok, it is fake...)

These are the parts I used for this PSU:
