To replace caps or not to replace...

My PSU has 2 caps that are bulged on the top and liquid was coming out. Its now dried up but both caps remain in the system. i was thinking of replacing the caps because it would be much cheaper than replacing the PSU that btw with 2 damaged caps still works. I do know how to replace caps but I have never done it myself. Should I replace the caps? I think it would be a fun little project but i do have to do something about the thermals inside the PSU because the caps died from overheating because both of them are right next to some heatsinks that get very very hot due to my GPU pulling more power then the PSU was originally meant to give out. So far i can't find anything wrong with the unit other than 2 bad caps some some hot heatsinks. if I can replace the fan with a better one for cheap and replace the caps for a few cents that would be fine with me because i don't have 80$ for a new PSU.

Replacing caps are easy, if they blow you may as well replace them.

Just replace it, get a 80 Plus 500W/600W PSU From someone like corsair or Seasonic, you can find then for around 50$

 

Caps are cheap as dirt.

Still won't be worth it, because that PSU is probably going to die or die very soon

Other the the 2 bad caps everything is 100% fine.

Touching caps can kill you?

 

If it's charged or something

Only big caps are a problem the tiny ones discharge pretty quick and aren't really dangerous at all.

So you may as well try to fix it to get the rest of it's life out of it.

The caps are failing becuse you have over strained your PSU, in doing so you may have damaged other components so this PSU is now unsafe, please replace asap, also running it with damaged caps, means it cant possibility be outputting a clean signal so god only knows what its doing to your hardware.

The caps are bad because they are nearly touching a heatsink thats gets to hot and they are swelled up not because the caps are overstrained

 

That's what I'm thinking. If the caps are in this state, just imagine how the other components are.

Everything seems fine I haven't actually probed anything but visually everything seems not burnt xD

Your PSU is connected to all your lovey hardware, why risk it?

If they have swelled they are failing regardless of the cause... if yoiu overstrain a cap it gets hot... same outcome different cause...

If you can do it then great replace away!

 

But, you really need to figure out why those caps are bad, not just replace and think all is well, they can just blow again after a short while if the issue that caused them to blow is still there. Not that you have other issues but need to check things out while you have it open.

I roll with sigs off so I have no idea what you're advertising.

 

This is NOT the signature you are looking for.

I always advise to not try to replace caps in a PSU. If you do, leave it unplugged for a day because the residual charge in the caps can give you a pretty hefty zap.
