Power Supply exploded out of the blue

[cheeyc]

My power supply exploded for unknown reason, other components are working fine...from what I guess from the photo, it look like a fuse exploded for me,

can I send for warranty to be replaced? Why main fuse, sub-phase fuse,3-pin plug, surge, all no blow but the fuse inside exploded

It exploded the moment I turn on the PC...no raining/thunderstorm. It sound like those electric mosquito racket when killing mosquito but 4x louder. I've highlighted the parts that blow out, can anyone tell me what is that? My 2 cent, dun buy anything from Aerocool, even my OEM delta still holds up well for 10 years, this unit just lasted 8 months . I did research this model from techpwerup, mostly positive feedback from the site thou. Could it be the PSU not compatible with Haswell system? In fact, I just upgraded the system a month ago.

Update: (close look)

It appear that another chips also burned, according to techpowerup review, it write"The standby PWM controller is a TNY280PN IC: the flagship of the TinySwitch-III series. The diode that rectifies the 5VSB rail is a PFR10L60CT."

Looks like a cheap capacitor in the build exploded... or possibly a resistor or fuse yeah, cause that's a funky looking capacitor.

Warranty is your best route... But I assume you have now opened it? I hope it's not noticeable...

PS: If you're in USA, I can make you a really good deal on a superbly reliable PSU...

Just be happy the fuse blew, and not your motherboard etc.

I never cheap out on PSUs since I'm paranoid of these things and I also want clean power to my components...

Glad it didn't take any other parts with it!

This is not cheap at all, it cost around US100/MYR300, for this money I can get Seasonic 520W or Cooler master GS series, I bought this because it has gold certified and modular design

 

[Deleted member 24505]

RMA it if you can, if not, throw it in the bin and rejoice at not having to replace anything else.

 

[R-T-B]

Yes, often times power supplies do bad things to other parts. That does look like a fuse at second glance though so you SHOULD be ok.

Ah well that might be why it didnt take any parts with it! You might just been unlucky

 

[R-T-B]

n-ster is right. I've had supposedly reputable brands blow up, even seasonics (1 anyhow), but the good ones almost never hurt the rest of the system.

Bad luck though...

 

[Deleted member 24505]

My mate bought a seasonic ages ago that let out all it's magic smoke on the first power up.

 

[R-T-B]

Not the magic smoke!

I do have Belkin surge that feed the whole system, that fuse did not blew out instead... now I not sure still want to use or not after return from RMA, or ditch this PSU and get other brands

 

[R-T-B]

Well, I can't be certain, but as said every PSU manufacturer has a bad day. As much as I want to tell you to buy a new one (because I happen to be selling one, hehe) I'd say try your luck with RMA process.

 

[Deleted member 24505]

Ditch it, and get a Seasonic or a Corsair.

Well... looks to be labeled "L 250U".
So, I would say it is a 250 micro henry inductor.

 

[Relayer]

It might just be the angle of the camera but it looks like the main cap is bulging too.

You shouldn't have open it. It might affect your RMA (as in they might decline to RMA it if they find out). If it's under warranty just take it back to the shop and let them deal with the RMA.

This. or any Sea Sonic OEM.

This is the closest photo I can get...it look like some glass debris inside the tubing. It written 250V not 250U, if the position is correct, I think Z1 mean zener diode/ F1 mean fuse...just my opinion

I am curious to know what happening inside, if I take to RMA only then it might happen again...no point to RMA

That's why your better leaving shit on 24\7 as it avoids the surge when you do turn things on. Good to hear it did not take any thing with it.


RMA it and hope they don't notice you opened it and sell the new unit if you think it happen again which the new unit might be a revised version and could of been just bad luck..

It make me some what weary of it as i like to stick which the actual company that makes the good PSU and not some one who uses parts of another like Corsair which in fact do not always use say Seasonic insides.

Might pay $20 or so for a Seasonic branded PSU but you can be rest assured it's what it is.

Aerocool isn't known for making quality PSUs. Seasonic and Enermax are.

I lose more quality PSUs on my server which runs 24/7 (not sleeping either) than any other computer which is turned off every night. Instead of refusing to turn on, they unexpectedly turn off. In terms of data, the latter is much worse. In every situation I've lost an Enermax PSU, no damage was done to components.

 

[Bo$$]

Yeah Aerocool isn't exactly top stuff. You should definitely RMA

I just had more stuff die when turned on then being left on..

Actually, if you don't know how (or wish to learn before working with electric circuits) to diagnose what caused the flow of increased current through the inductor and caused the failure; then, you can try the rma or toss it and get a good, quality PSU.

That inductor looks to be on the high voltage side of the transformer. And, is probably being used in a circuit to filter out unwanted HF on the AC.

You should know and use proper practices for handling electricity, before working with it; otherwise, your playing with it and playing with your life.

I would encourage you to take a course.
