If capacitors on the PSU fail, does it continue working with bad voltage regulation?

[LOST TALE]

If capacitors fail on a PSU, does it continue working whilst providing bad voltage (high jitter or w.e) to the components?

It would depend on what capacitors failed, if it was a capacitor in parallel with other capacitors it could still work. But if the capacitor that failed was in series that part of the PSU would stop working.

What's most likely? PSU fails or PSU continues to work providing significantly damaging power (causing 7 years gpu to last only 2 years)

Most likely it would stop working or if it does it would just turn of randomly once in awhile. If it is damages you would want to replace it because it could kill your other components.

So it could shut off at a gpu load of 180W but then stay stable at 250w for days? Meaning would it be inconsistent and hard to diagnose or easy to trigger?

Would you kindly look at these images and opine? I'm not sure about that big capacitor in the middle. Is that glue or a leak? lol

That's not a capacitor.  That's a transformer.

 

The lamination is cracking and that's why you're getting all the noise you're getting.  You're hearing the copper from that transformer vibrate without any insulating material.

If a primary capacitor was bad, the PSU wouldn't work.

If the secondary capacitors were bad, then they would not properly filter ripple and this can kill your components downstream.

The crackling noise only happened during a Wargame Airland Battle at 110w. Runs quiet at full 250w gpu load on other games.

It's also been well maintained with a fan filter at the bottom (though it would have been clogged a little sometimes but if the fan is temperature instead of load based, it would have been fine.

 

So is the way the transformer bad for power delivery?

Power supplies operate a different frequencies with different loads.  That's why it would make the noise at one load and not another.

 

You don't want a transformer to fail.  Another reason not to use a 7 year old PSU.

What happens if the transformer fails ? XD

Google it.  I'm done here.

You get 300V right through your expensive components
