I'm using a computer PSU to power several controller boards and sensors. To be more precise, I'm using the 24pin ATX connector wires to power everything.
There are two 12V+ wires coming from the connector. I've noticed that one of these wires is connected to a ground wire via a capacitor. While the other wire is just a stand alone 12V+. I assume the capacitor is to smoothen the power supply on that wire?
Can anyone explain the reason for the capacitor?
