Need help with my PC's Power Supply.

[Narek]

For the last week my PC froze twice(that never happened before). The first time it froze with buzzing sound in headphones. The second time it gave me the blue screen of death and automatically restarted. I decided to check it. And when I opened my power supply I noticed one of those battery looking things slightly moved and something spilled under them. The battery is to firm to touch(feels like that's the way to be). I never payed attention to the inside of my power supply so I am not sure if smth is wrong with it or not. I will attach photos of it. So please help. Tell me what to do. Do I need a new power supply? Is it risky to boot one last time to send some important files to my other device? (In case it needs replacement). Thank you in advance.

Those black batteries are capacitors and they must not be bulging. If you see that, you better buy a new PSU for your own safety.

 

Freezing and BSOD can be caused by unstable overclock btw. So there might be a correlation with CPU drawing more power and damaging your PSU.

Those battery looking things are called capacitors. You shouldn't be really messing around with things like that, if you think it's faulty scrap it.

electrolytic fluid.

They are specifically Electrolytic Capacitors and that is the electrolyte

Never open a PSU u can get a nasty shock.

If the PSU is faulty replace it.

[RollinLower]

if you can source some new caps you could just solder them on there, tough i think just buying a new PSU is the better option here

if you have even basic electrical knowledge opening a PSU is perfectly safe. otherwise i agree.

1) Do not open a power supply unless you know exactly what you're doing, because it's an electrical hazard.

 

2) Those are capacitors, so clearly you don't know what you're doing.

That is glue that is used to reinforce through-hole capacitors. The capacitors are completely fine.

 

4) The capacitor has not moved, they are sometimes not centered on the markings on the PCB when soldered and that's fine.

You can DIE from the nasty shock. OP is really lucky if he messed with faulty capacitors without even knowing what they are and nothing bad happened

Please do not disassemble power supplies if you don't know what you are doing. These are capacitors, and you can get hurt from a shock. I wouldn't even bother reassembling it now. Dispose it responsibly and get a new one. Something like a TX550 isn't to expensive and is of good quality.

 

Edit: the BSOD doesn't mean it's the power supplies fault, most probably not. While having PSU problems PC's usually just shut off.

Thank you for your advise. But for example what should I do if power supply fan gets dusty? How can I clean it without opening the power supply?

honestly that looks like the epoxy they use to make sure the caps stay stuck to the board. left hand cap looks a little bulgey but maybe that's due to the way it's sitting on the board as it looks ok from other angles

 

OP, do yourself a favour, don't open these again in future - capacitors store a fair amount of energy and unlike a battery will release it instantaneously the moment they get a chance. those two thicc bois are most likely mains filtering capacitors and will be charged somewhere between RMS wall power and peak wall power, so they will hurt. quite a bit.

 

looking by the genera construction of that PSU it seems quite old, maybe consider replacing it

 

if a capacitor vented badly enough  to spill goop out like that, you'd hear it hissing and definitely smell it

I guess it's old. I was using it since 2013. Thx for support.

Compressed air or a bicycle pump should work. But please, do not open it.

imlearning so much from here man. Im gonna start checking this stuff everyday

no i meant checking the forum everyday its like twitter for It techs its dope

Yes, because your PSU is total garbage.

You can't "repair" it.

That's like trying to make an Opel Kapitän comply with modern Regulations. You just can't.

 

Just replace it with a somewhat good quality unit and don't bother with that piece of Pollution...

Ding ding ding!  Correct answer!

At any rate @Narek:  That PSU "may" have done you well so far, but that's an old Leadman made unit and is KNOWN to slowly kill other components with horrible voltage regulation and lots of ripple.  If it weren't for Leadman killing a bunch of PCs after a couple years of use and having to figure out why, I wouldn't have ended up as a PSU reviewer.

 

Replace it at your soonest opportunity.
