These are for All Amiga setups including UnAmiga ITX, MiSTix and Raspberry Pi4 and Real Amiga systems and NOT for high end PC builds.
You can use on a PC but only with 65watt TDP or lower and on board graphics. Basically, just know what you are doing if building a PC.
The PSU has a temperature sensor so it is silent until around 30 degrees C, then the fans start to ramp up slowly.
Please note this is not a silent PSU, but it has been configured as good as possible to be unobrusive.
