    Hi,

    I'm thinking about building my own PC, but I don't quite understand what anti-static precautions should be taken. Obviously, nothing will be plugged in, but is there anything I'm missing or not understanding?
    Also, are anti-static wrist bands essential? Also, would carpet work as a good working area?

    Thanks

    Anti static precautions are vital, you can do permanent damage to the internal hardware.
    A carpet is not ideal as this can increase static in the body just by walking on it.
    Personally I use antistatic mats and wristbands, I just dont want to take a chance on damaging anything.

    Basically just be careful. I always make sure I'm physically touching a metal part of the case as I install/connect things. I do use an antic static band and they are a good idea, but half the time it will pull off the case and I'm working with it dangling loose. Carpet is more likely to generate static than an uncarpeted surface. Remember a modern case/MB will have power to it if plugged in and the back switch (if there is one) on. Something you will probably remember when you assemble everything, but can be forgotten while troubleshooting.

    Thanks, do you know of any work surface other than something I would have to pay for?
    Thanks

    When you earth yourself does that mean you touch a metallic part of the case?
    Also, when you build your PCs do you have the PSU plugged in but not on at all times (except for when you boot and things are complete)?
    Also, how do you turn off the actual PSU? Is there a switch?
    Thanks

    Working on carpet is not a good idea, I'd try to do it the kitchen. You don't need any special surface, a table will do fine.

    Touching the case is indeed a good idea.

    Most power supplies do have a main switch on the back. There's no need to have the AC plugged until you done assembling the computer.

    Oh okay, thanks for the help, and thanks for the help I think you gave me previously (a month ago maybe).

    Touching the case really does not do anything unless the power supply is installed and plugged in [however not on]

    I ground myself to something like a light switch or wall socket screw. This will remove any static charge from your body. I agree; try to work on tile, hardwood, etc just not carpet.

    I do confess that I have assembled systems on carpet, however I do ground myself each time I handle a part.

    Actually touching the case does do something. I am a microminiature electronics repair technician from the Navy (Retired) ESD is an extremely important issue. Touch a bare metal portion of the casse Brings you to the same potential as the case there for no further Static Discharge will occur. This is not a fool proff method but it is better than nothing. No the powersupply does not need to be connected to the wall for this to be effective.

    I have seen microscopically, what damage can be done to a micro circuit and it looks like an atom bomb has been dropped on a city.

    I think we are referring to two different things. Touching the case will normalize you with the case, however it will not remove the static charge from your body. Touching the case with the ps plugged in or touching a wall socket / light switch screw will remove the static charge from your body. Using a wrist strap will do this also [although I cannot stand the things]

    In any case try and not touch the connectors of any parts; hold them by the ends of the board.
