    Dont ever open a PSU unless you know what you are doing, by the sounds of you nearly getting electrocuting would suggest you dont. (dont mean to sound harsh, just dont want a fried guru lol)

    That does sound strange but it can happen sometimes. Seasonic you will not have any problems with, i find them the most reliable.

    Yep.
    The capacitors in a PSU can take a long time to discharge, weeks even.
    If you touch anything that is directly connected to a capacitor it can give one hell of a shock.
    This can cause a deep burn, numbness, paralysis or even death.
    The larger the capacitor, the much worse.
    PC PSUs have large capacitors.

    Capacitors can be discharged with a 100 or 200 ohm high power resistor. Never use a wire because the arc can harm your eyesight or burn you with the molten metal flash.
    But you probably wont have access to the capacitors terminals until it is disassembled which subjects you to exactly the risk while disassembling that you want to avoid.
    Think of a capacitor as a battery that can release all its power in a split part of a second.


    Leave it to the professionals, the potential damage to the rest of your life is not worth the small saving.
    To clean it do as suggested earlier and use compressed air.
    Careful to not direct it at a capacitors base because they can be damaged.
