Hang on, the computer power supply is still plugged into the motherboard? Well, there is your 5V load.
I still use my motherboard for now because it's the only way the power supply starts but I'm trying to make the power supply start without it.
I tried with a 10 Ohms 10W resistor I bought this morning but surprisingly it's still not working. As you can see on the photo, I plugged the resistor with a red and a black wires and I also have a jumper wire from the grey wire to a brown wire. When I plug the green wire with the white one, the power supply starts for a second and stops. I don't understand what's wrong, probably wrong wiring. Someone as an idea?
