    Why does everyone want to run dedicated power lines for a computer? I'm pretty sure they don't draw that much power, and if it had anything to do with interference that wouldn't help any since the lines all go back to the same place?? I was always curious about this

    for the reason that interference can adversly affect electronic equipment (which can be expensive) and can cause data loss (which can be critical).

    un-interrupted porn viewing is a good thing

    I've got a dedicated 20 amp line for my setup, but I've got a computer,
    external hard drive, an audio rack including a power amp, lamp and monitor.

    All together, it feeds 13 electrical components, including 5 ac adapters.

    I sure wouldn't want all of that on a shared line with the rest of the house.

    In an idealized situation where I was building a new house or I had the money to bring an electrician in I would do a dedicated line.
    But I won't live in that situation any time soon and you probably don't either.

    As far as how much power your computer draws it can be more then you think.
    The CPU alone can draw as much as 100 watts. Like running a 100 watt light bulb 24X7.
    A lot of the stuff in your computer only draws power when it is active.
    Your hard drives, DVD and CDROM drives and even the floppy drive all have 12 volt connections.
    I don't remember how many volts run across the PCI bus.

    All of this stuff is terribly sensitive to power spikes.
    A power spike is when more then 120 volts run through your electrical system in your house.
    A high enough power spike will kill the stuff inside your computer.
    The best example of a power spike is if lightning hits the pole outside your house.

    But there are other ways too. If you have a malfunctioning appliance plugged into the same line your computer is on this can cause a power spike.

    Also a brown out can cause problems. A brown out isn't as dangerous as a power spike. A brown out is when less then 120 volts is running through the electrical lines. While a brown out won't break things it can cause problems like your computer locking up or your video card doesn't seem to be working right. It can even cause hard drives to stop running.

    These are all good reasons to have your computer on a seperate line.

    Like I said in an idealized world you would have that. But most of us are not in that situation. And most of us are doing fine.

    Hell, I live in a house that doesn't have grounded outlets. I have to use one of those 3 prong adapters for my PC. It is a horrible thing to do but there are no choices. I will probably pay the price some day.
