+# Power-Supply
+
+The MAMI needs a fitting ±12V Power supply. This obviously depends on the size you are going for. Anything up to 10x10 should be able to be powered by the [3WPSU](https://code.hfbk.net/sdiy/3wpsu) with a  USB-B Phone Charger as one output module should use about 10mA (to be verified) and the 3WPSU is able to deliver up to 125mA per rail.
