An ATX PC power supply has multiple voltage outputs. If yours is following the standards (most do) the Blacks wires are Ground, the Red Wires are 5volts and the Yellow wires are 12 volts. You should have several 4 pin Molex connectors (like this https://tinyurl.com/ydggtwsl) You want to connect your Motor to the Yellow and a Black on one of these connects - and dont forget to include the relay in the circuit so the arduino can activate it.
Also, you may not be aware that you need to make sure that your ATX Power supply is ON.
Just look for the green wire in the cable from the PSU and follow it to the 20 or 24pin ATX plug.
Then use a piece of wire to jump this Green wire to any of the Blacks on the same connector.
Then just tape it in place now the power supply will always be ON when plugged in (remember that and be careful) I like to tape off all of the connectors that I am not using just to be extra safe.
Nicely done. Thanks for sharing!
