    Can someone please explain to me in a simple yet detailed way exactly what a power supply in my computer does?
    Also, there are labels on it that say 120 VAC and,
    12, 5, and 3.3 VDC. What do they mean?

    Thanks :)

    It's function is to provide varying voltages to the motherboard and other components that make a PC function. The voltages are 12V, 5V and 3.3V. My understanding of VDC is variable direct current. By the same token the 120 VAC refers to Variable Alternating current....that enough?

    Power outages in the form of variable supply from electricity supplier? or issues with supply variations in your house?

    If you are looking to protect your PC from power cuts - then you need to source a UPS (uniterruptible power supply) - type in "UPS for computers" in Google. If you want to maintain clean power that doesn't fluctuate - try Monster - surge protector and power cleaner. Expensive but damned good - can add significantly to life of electrical goods protected by it.

    Should have checked with wiki on definition! - my apologies on VDC and VAC - V is for Volts not Variable! (Thanks Brite750).
