What would happen if i used Exploded PSU?

[Exaco]

Hey guys, so this is my second PSU dying ( both was faulty on arrival most likely ), yesterday while using XFX XTR2 650W ( Focus Plus/Prime rebrand ) i've noticed that PC shut down while on idle, turned back on everything works fine, thought mby it went to sleep or something. This morning PC doesn't boot, tried a bit of troubleshooting like checking cables trying different wall etc.. Nothing works.

So i wasn't sure if the PSU is dead or maybe Mobo is dead, so i took my old PP11 600W which exploded and connected it to mobo only, i know it was risky but the only way to figure out if its the PSU and with the old exploded PSU the PC booted, all fans started spinning, lights on etc.

Is there any chances the old PP11 is still fine and could be used while i wait for RMA? Well since it works normally kinda, but ofcourse has risk of second critical explosion or not?

Explosion:
Basically i heard some noise, PC turned off then i saw smoke from below ( small amount, like 1/3 of cigarette smoke exhale ) coming and i found some nasty smelling liquid leaked out on the floor and dust filter/fans and never used it since then.

I wasn't able to see any exploded caps looking through the "grill/mesh".

You're not explaining what you mean with "exploded", you know. You're not giving us anything useful to go on by.

Never ever ever should you use a PSU you think might be faulty.

That's a blown electrolytic capacitor, then. I wouldn't use the PSU, even if it seems to be working at the moment -- even if there was nothing else wrong with the PSU and you just happened to have one with one bad cap in it, your system would most likely be unstable. Then, on the other hand, there could be something else wrong with the PSU as well and then you're risking your mobo and everything connected to it.

Ironically if i ordered brand new one i might think it can be faulty  Just like these two were.

nothing wrong, you bare the risk any connected parts may blow as well

Are you using the same cables?

The modular connectors on the Pure Power 11 CM and XFX XTR are physically different.
Pure Power 11 CM uses 12pin for PCIe and single row of 5pin for peripherals. The Motherboard and CPU cables are fixed.

XFX XTR uses 8pin for PCIe and 6pin for peripherals.

While it can be an issue for some other power supplies, you'd have to get pretty creative to use the wrong cables between those two units.

I know the CM and the XFX use different cables, I was referring to the two XFX-es, the ones that died last.

Using always these that comes with PSU, since i do not have any "Mod cables".
And the PP11 wasn't modular.

Not necessarily.  Typically it's MOSFETs and diodes that flame up and smoke when the blow up.  When you see those videos where the PSU explodes and there's a large flash and a bunch of smoke, that's typically the primary's switcher.

never risk it with a psu

Yep.  Good way to kill all of your other parts.

Neither MOSFETs or diodes leave any sort of liquid behind. Also, I take it you haven't seen how an electrolytic capacitor blows up.

LOLOLOL!!! 

 

Of course I have. 

 

I do admit that I missed the part about "liquid" in the OP.  My bad.  Though 99% of the time when someone claims they've seen liquid in their PSU, it's actually just the caulk. 

 

But now that I see the sentence in the OP about liquid oozing out of the PSU, I do agree with you. 

 

Reading comprehension of forums on a phone isnt the best.

Okay now i'm curious if i was just unlucky with faulty PSU's or there's an installation problem in this 5store appartments that wasn't renovated since soviet times.

So what exactly happens to a decent PSU if there's power surge since it's the worst that can happen right?
Note: I've used OCZ ZS for over 4-5years in worse conditions such as trash case w/ 0 airflow, the PC was running nearly 24/7 and nothing happened, it all started with the new "better" ones in combination of PC platform upgrade.
