I an thinking of upgrading the Power supply for my K8220. As mentioned I various posts, I will be using a separate 24v supply for the heat bed. As for the rest (main board, stepper motors etc), I will also change the stock psu. There is one slight problem, I cannot find a 15v psu for the main board. Will a 12v psu be enough, Please find below the specs for both psu

I put 16 V from an old IBM laptop. It’s safe to use anything up to 20 V. With 12 V it will take ages for extruder to heat up.
