    Default PSU unit went up in smoke today and looking for cause?

    Hi,

    I had a Corsair AX1200 psu working fine for last seven years. Today after pressing power button I heard a ‘Ssssst’ sound and saw smoke. Smelled like burned plastic. I unplugged everything and used a psu tester to verify the psu was no good and now non functional. So was wondering what happened that caused the psu to fail? Power surge? Excess draw? Old age?

    Thank god my two 1080s are undamaged.. Thanks.

    Ready for the hypotheses on this mystery! Sounds like a fun investigation.

    When did you buy the AX1200? No longer under warranty? If it was, I'd suggest sending it to Corsair for failure analysis.

    But given its age, it probably just died because it's old. I mean... 7 years and the pfft can hardly be called "infant mortality".

    I almost spat my beer, while reading this. XD This is as dark as the coffee I drank this morning.

    But yeah, I could say it was the 7 years of use, I'm also counting the days before my EVGA 850 G2 die, almost the same age. u_u

    LOL! No.. They really call it that.

    A product that is not DOA, but does not last beyond warranty is said to have infant mortality.

    It's slang... but I didn't come up with it.

    Now every flagship PSU has 10-12 year warranty. 7 year of operation isn't old age at all.
    It's been a hard day's night and I've been working like a dog.

    Sounds like one of the capacitors bit the dust. The "hissing" sound is pressure blowoff from the electrolyte getting cooked and steamed out.

    Probably got unlucky with one of the KZE's being right at the bottom of acceptable quality range... A decently skilled tech should be able to save the unit, if you care to try.
    Careful what you wish for... You just might get it.

    Default Instant mortality not fun

    I bought it 7 years and 2 weeks ago. So two weeks past warranty so not sure if corsair would honor the warranty or not. I used a PSU tester to test it out and every time I plugged it in it made that 'PSsssst' sound and a let loose some smoke. Hope it didn't fail because of anything I did as far as my build goes with two 1080's, a 6700K cpu, and a few hard drives. Luckily nothing else got damaged at all.

    Anyhow got my eye on the Seasonic Titanium 1000 Watt Prime model. Only thing is read it has issues handling spikes in the current but still Jonny gave it a great review. Also like the silver bling on the fan grill though I would have to flip the PSU in the bottom of my case to show off the silver.

    Thanks

    I'm sorry I meant the review that was posted on your site. Guess it was Oklahomawolf who did the review.

    Anyhow Corsair approved my Rma but got that itch to buy new hardware so still considering the Seasonic Prime Ultra Titanium 1KW.

    What to do ...

    Thanks
