How do I connect this crane machine motherboard to my power supply? What connectors do I need for the power supply header pins?
Obviously, these spade connectors (the forks) can't fit onto those pins. I suspect the company sent you a power supply from a bin full of power supplies and didn't check whether it actually worked for this product. This is what you get when you buy cheap things on Ali Express!
But, oh well. I assume you can't get a refund.
Usually, this kind of cheap product does work somehow - they aren't trying to scam you, you just get what you pay for. The good news is that you have a power supply that has the right voltages on it (and also 48V which the motherboard doesn't need). The bad news is it has the wrong connector.
So, here are some ideas. You can decide which one is easiest for you. I can't guarantee that any of these are particularly good ideas, but they are ideas.

Figure out what kind of connector fits onto those pins, and cut the spade connectors off the cable, and attach the cable to that connect instead. Then plug it in. I think this is the most reliable option. The only downside is that you have to find the right connector.

Cut the spade connectors off the wires and strip the wires. Wrap the stripped wires around the pins as tightly as you can, then add solder, then add copious amounts of hot glue and electrical tape just in case.

Take apart the power supply (caution - possible high voltage - discharge capacitors - they probably won't be charged but discharge them anyway) and remove the connectors. Then, solder on different connectors, or solder the wires directly. Put it back together. Make sure the connection doesn't touch the metal case underneath the circuit board.
This idea has a bit more risk since you're modifying the power supply. And perhaps you can't take apart the power supply, in which case you can't do this.

Buy another power supply. Also low risk, but the downside is that you have to buy more power supplies. You might be able to find one that outputs 24V, 12V and 5V, but if not, you could get more than one, and connect the grounds together. They usually come with screw terminals on them, so you shouldn't need to modify the cable.


The worst things that could go wrong are that you blow a fuse, make the power supply go bang, and/or fry the motherboard.
