    ok, ive read over and over again on the forums about how you should never work on a psu when its plugged in (duh!) and about how you should fully discharge the capacitors before attempting to mod it.....

    im shortly gonna be modding a psu to see how many mobo's a single psu can power ( see here ) and i see many different ways of discharging a psu.

    im a newb, and i dont own a dremel ;) so whats the best way to discharge a psu? maybe some modder would like to build a 'psu discharging tool' and post it as a project log or something?

    im guessing the easy way is to basicly attatch a bulb to the capacitor pins and wait for it to stop glowing, thus no more electricity is in the cap, but it would be a good tool for us newbies to have, something that we know will discharge the psu properly. can i just attatch a 'normal' light bulb, like the one i put in my lamp? or should i use another kind, i did see one guy mentions a christmas tree bulb, is there really a difference?

    any more experienced modders want to comment? even just to say "yes, that will discharge the psu and you wont fry yourself" would be nicely re-assuring :thumb:

    unplug the power from the back of the PSU, leave the 24pin connector in the motherboard and press the power button, that should discharge the unused power from the psu by trying to start the system devices.

    I beleive thats how you do it.

    Yeah just like Carbon said is how I've always done it. When you push the power button your fans will try to spin a little and then that's it.

    Of course I'm always still very careful and don't just go poking and prodding everything inside the PSU. No point tempting fate. :hehe:

    you could hold it in a bowl of water for a few seconds, that will most probably discharge it.

    <DISCLAIMER> that is a joke, so if there are any idiots out there and they want to discharge their PSU don't use this method! actually, if you're an idiot and you know it, stay away form PSU's alltogether. dremels and jugsaws too no that I think of it. actually, just don't mod! </DISCLAIMER>

    Sticking a flat headed screwdriver into the thing and moving it around until you hear the big zap and your good to go ;)

    so the plan is....

    so as far as i can tell the plan is.....

    grab the psu with both hands and dive into a bucket of water whilst grabbing a screwdriver in my dripping wet hands and prodding the shiny bits inside at random..... thats bound to work! :grr:

    oooor..... i could have at least some sense of self preservation and just try to start the pc whilst its unplugged. :clap:


    i think i'll go with the second option :thumb:

    conect a wire to the ground pin and plug it into the ground of the wall. If i have to explain which is which, don't do it. Let it drain for a day, as well as pushing the button. Not doing this has shocked the crap out of me at least 3 times as well as burnet a whole in my floor. :sigh:
