I'm going to be rehousing a PSU soon and I am aware of the dangerous voltages that are in the capacitors inside. Instead of just being careful not to touch them (which will be difficult), is there a way of discharging them to make them safe to touch? Thanks!
If its plugged into your computer, keep pressing the on/off button. if its not, connect the green wire to the ground on the atx connector (i think its green anyway, check it).
keep it plugged into the mobo, shut down the computer, or restart into DOS if you can do it easily (I think the xp command prompt will work if you get to it by hitting f8 while booting), unplug the psu, push the power button, it may come on momentarily, wait 1 min and push the power button. The caps should be pretty empty by then. Without a mobo, short out the green wire on the ATX connector to a black one and wait for a minute or so. Some one should sticky this or another one of the PSU discharging threads.
Just as a test...I had two psu lying around so I powered them up and by the time i got the case off as fast as i could the caps were discharged on both psu's.
That isn't too healthy Most of the times, you can turn the comp off, unplug, hit the power button, wait a few minutes, hit it again, and hit it once again another minute or two later Any shock after that shouldn't be much more of a tingle (trust me, you don't want to get hit by a strong capacitor, I still have two burn marks from when I was playing with a camera and accidently touched the capacitor)
Why not? Yesterday I cut off mains to the house when my puter was on, then i turn mains back on and power up the PC no problems at all.
there's a reason windows has had either an exit or a shutdown option since the beginning. windows tends to put stuff on your hard drive, i.e. temp files and such and not shutting down properly leaves that stuff there. there's probably other reasons as well.
