Guide 12 volt to 24 volt using buck converter

[chungus]

My 24 volt power supply in my ender 3 pro died. I have a 12 volt server power supply with breakout board which I use with buck converter as a bench supply. So I'm thinking if I can use that buck converter to power my ender 3 as it gives up to 30 volts at 3 amps or the amperage is too low?

Amperage is low, the original supply wattage is around 360W, so with your buck converter you are nowhere near to that.

Amperage is low, the original supply wattage is around 360W, so with your buck converter you are nowhere near to that.

Oh yeah just checked it needs around 14amps, I have two of these power supplies, I think I'll connect 2 of them in series to get 24volts.

In that case make sure that your 12v power supplies are both rated for at least 180W, because 15amps will be drawn from both of them @12V at peak times, because of the series connection.
