What are the capacitors on the motherboard for?

In layman’s terms, a capacitor is a tiny electrical component soldered to the motherboard. Capacitors perform a couple of different functions. First, a capacitor conditions DC voltage to other components (e.g. the video card, hard drive, sound card etc) as a way to provide a steady stream of power.
