Did I kill my PSU?

I was having fun with some case modding, and I took a second PSU and hotwired in about a half a dozen fans that I took from old broken PSUs. But while I was doing this, an open wire touched the case while the PSU was on. I believe it was a 5V line. Sparks flew, and the PSU shut off. When I tried to turn it back on, the fans moved about 2mm, and moved back that same amount when it was turned off. Is it truly dead, or is there something that I need to reset to make it work?
 
Why did you have the psu on? I dunno if its dead but iv heard of simular stories when the next day it just starts to work again.
 
1.Try replaceing any [insert word here that I cant remember]* if there are any.

2.I would undo everythinh except the connection the the mothboard and try it, sound's like something is reverse grounded.

*They are ussaly little tubes, they they will blow out to help protect electronic's from blowing out themself's.

Hmm

A simmilar problem came across in my case. There is some short protection or whatever it is called. In my case, the PSU got "back on track" in about 3 hours :))

I had it on to run the extra fans because i did not want to hotwire my main psu

are you talking inside the PSU? And what is the definiton of a little tube? If you are talking about a fuse, then I know where that is.

It is not connected to the motherboard, and what is reverse grounding?

That is what had always happened in my experience.

Well I will see if the fuse is still intact, but if it is, does anybody else have other suggestions?
 
Well either the fuse is intact or it does a really good imitation job. ;) When I turn it on with the case open, I get a sllight buzzing noise that seems to come from the big yellow thing (I think it is the transformer, it has tape-ish stuff wrapped around it) like it is trying to turn on, but just can't. All the connected fans move, but two move forwards and one moves backwards. The fan inside the psu does not move at all.
 
Hmmm

Man I hate to tell you this, but I think you really did mess up something. I thought it would be working after some time, but there must be something seriously wrong when what you are describing starts happening.

I don't really care if the PSU dies, I am just trying to learn by taking things apart. Do you have any idea what happened? This is an ancient PSU, only 200W and 8A on the 12V rail :eek: so I don't care if it is broken
 
Lol

Cool.... I would not really play around with the insides of PSUs if I were you. The capacitors can still hold considerably strong charges even after the UNIT has been shut down. I say give it a bit more time and if that does not fix it, then I guess noone will...:)

haha I took apart a capacitor once:D and if I have to choose how to die, this is it. Just a few (dozen) years from now:)

and heehee I found a PSU with 3.5A on the 12V rail, and it only turns on when i shut it off :confused::eek: maybe I will throw that one out

but anyway thanks for your help, but no matter what you say, nothing can stop me from taking things apart. At least I know what being shocked feels like all to well
 
200 watts? are you serious? seriously, like, unless you were doing this out of boredom, it really doesnt seem worth it to just not buy a new psu. i tend to think this was just an undertaking inspired by curiosity.

No, this was definitely curiosity. My computer does not need 9 80-120mm fans cooling it :D but this is what I like to do, so I do it. And I am not going to buy a new one, I will see if I can get that 145W one to work:cool:

LOL! So do i...For mostly the same reason, the first time was with a electric lawnmower though...I ran over the cord LOL then bascily curoisty touching thigns while taking them apart....
 
He he he, i took apart a HBB and plugged it in, those platters really do spin fast, you can have som much fun dropping things likie staples onto it when its at max spin, he he he, but dont touch it, they hurt....
