My power supply looks a lot like the Mega Watt one listed above, but I bought it on amazon for around $30. It’s a 12V, 40 amp power supply that is adjustable. I usually set the output voltage at about 13.8 -14V. You can either connect it to the downstream post of your master relay, which takes the master relay out of the picture and powers everything on your master bus as soon as it’s plugged into the wall outlet, or connect it to your battery and use your master switch to turn it on. When you do it this way, your master relay will be powered all the time it’s on (like when you’re flying) consuming a small amount of energy, but the battery, which is a large capacitor, smooths out the input from the power supply. I have a PC680, so it also charges the battery. This will charge my aux battery (12V sealed lead acid/8 amp) if the master switch is on. Aux bus is powered from the switched aux battery, isolated from the main bus by a dedicated one-way Schottky diode. This is a very handy way to power things up even after your IP is built. Updates, configuration, troubleshooting, mods, etc..
