DO NOT OPEN POWER SUPPLY *IN HOSPITAL*

[ygoodhh]

Yeah, so the other day I was opening up a power supply because the fan stopped spinning. I thought the fan went out and I opened the PSU up. I accidentally touch on of the capacitor (didnt know they were dangerous) and now I'm writing this in a hospital.

 

People do not open up PSU unless you are super confident in your knowledge around this stuff. 

 

Getting electrocuted isn't fun don't try this at home.

[Hip]

Those warning stickers are not made out of fun!

 

I wish you a good recovery.

[Shimejii]

Yeah this is pretty well known not to fuck with the PSU in any way shape or form. When you have something with High energy capacitors and other components that can generate 500-1500 watts, best not to touch it. 

[LienusLateTips]

There's a reason why my PSU has 7 different warning labels saying "do not open unless you are professional"

Ouch, have a speedy recovery.

Dear me. 

Natural selection at its finest.

Electricity is dangerous, you know.

Why visit the hospital?

That's why you always empty the caps.

Just to give your guys a detail version of this.

 

I was fixing my friends pc after he said his computer would shut down under load with normal temps for CPU and GPU.

The case was open when we were testing I noticed that his PSU fan won't spin despite the system under heavy load.

 

I determined that the power supply was bad after I put mine in so I decided to open up the PSU to check whats wrong. He's pc its pretty old so I thought it could be dust build up or something stopping the fan from spinning.

 

MY BIGGEST MISTAKE HERE: I opened the PSU while it was connected. Of course, I found out that it was connected then I unplugged the PSU for safety purposes (I thought that was safe enough).

 

Then I grabbed the PSU in my hand to inspect, then yeah.... I dont know anything after that.

 

According to my friend (thank god he was with me) the ambulance came and they used a defibrillator on me. I think after that I was fine but I was still passed out cold they just sent me to the hospital after that.

 

This happened yesterday.

It'll kill you even if the powers off.

 

You should read warning labels, they are there for a reason.

[Quadriplegic]

Capacitors can keep the charge even if they were unplugged for a while. Louis mentioned how dangerous power supplies can be in the iMac repair video (iMac Pro has  open power supply... That's why it's not meant to be opened, not because some hipsters said so).

you are 100% right. I'm kind of an idiot when it comes to safety stuff. Once my cars jack stands failed while I was under luckily I crawled out in time. I definitely need to be more cautious around stuff with warning labels.

Never ever touch the internals of a PSU, even if disconnected, unless you abso-freaking-lutely know what you're doing. 
PSU capacitors can maintain a stored charge for weeks or even months.

 

Take a good rest and get well, OP.

(not to ride on your injury OP. I'm glad you're alive)

this is common knowledge and gets said just about everywhere whenever someone on youtube or in any guide does something with a PSU that is more than just plugging it in.

 

Capacitors can fuck people up easily and instantly as soon as you get to voltages high enough to overcome the resistance of the skin.

Agreed. People need to know that their PC can very well kill them. Even tho they are harmless most of the times.

Happens to me way before you did but not that critical.

I pretty much touch the capacitor right after it was unplugged so I guess that's why i basically died for a short while

IMO,not worth it unless you really,really know what you're doing. Even then it's just better to spend $40-50 or so on a new PSU instead of risking serious injury.

when i did it .i did not open because it was not working .

I did it out of curiosity .

I havent watched that video yet. If I did before I opened up that PSU I probably won't end in the hospital...

maybe this is different somehow but i di this once an was fine half an hour later or so. same situation fan made rateling noise opened it to change the fan. was just about to test if my replacement fan would work and shocked myself and triggered a fuse.  still.. put it back together after that since the psu still worked perfectly fine. mayb i got less power in my shock? idk

I think by that time the capacitors weren't nearly as charged as right after they are unplugged. You got off easy man.

[SImoHayha]

Common knowledge is if the fan is dead in a PSU you get a new PSU period my professor who works in the IT field said just get a new PSU instead of trying to replace  the dead fan it because this will happen to you. Lucky you had your friend or you would be dead on the floor for about a couple of hours.
