So all of the printers run on either 12v or 24v. All of the printer mainboards will take either. The heaters are meant for 12 or 24v but to be honest we can tune the PID loop controlling the PWM circuit driving the heaters so that is really a non issue and the heaters while saying 12 OR 24v can be used happily in either scenario. The fans on the other hand as well as lights you may have on your printer might care about 12v or 24v. Otherwise there are different wattages available but all of these 3d printer power supplies are 12v or 24v. Your ender 5 has a 24v power supply that is no more than 350 watts but might be as low as 270watts. Either way it is fine for any mainboard or electronics you want to throw at your printer.
