Starting PC made PSU go up in smoke

[Ertishop]

A few days ago I woke up and wanted to play some more diablo, when I hit the power button I just heard a pffffffffttt sound and saw in the back of the pc how a bunch of some got blown out(literally as if someone was blowing smoke out) I directly unplugged the power cable and then I started recording, I was looking if it will catch fire so I throw the case out or rescue my GPU inside but afterwards nothing happened, after that I didn't touch it, my first unprofessional guess was my PSU is broken and hopefully nothing else I ordered a new PSU and will try it in a few days, I also was using a power cord plug that protects from electricity spikes (don't know the English name).

Update: My new PSU arrived, MSI PSU MPG A1000G PCIE5 1000W 80+ GOLD i was gonna change the PSU and all the cables that come from it but then got too lazy, left all cables inside just replaced the PSU first boot it kept restarting but after removing the ram and plugging it back it works fine now. the old PSU had some oily liquid leaking out of it.

I'm here now to hopefully get a bit educated and ask why could this have happened was it any bad practice i had or just bad luck, what inside the PSU made all this smoke and in general what even happened really here

everything except the AIO was bought august 2019, AIO was beginning of 2023

 

In 2019 when i bought this stuff it was literally more then 10 months worth of my salary in the country i live and i have an okay salary, now this year just the new PSU was a bit more then a quarter of my salary, tech stuff is very expensive here, thats why i went with a bit cheaper one this time 

 

these are the specs if it helps with anything

Did you just leave all the old cables inside? Hopefully just extension cables and not the modular cables from the corsair PSU. If it works, then you're just lucky thats it's wired the same way and therefore works (same OEM). My guess is that you didn't clean your PC and dust was shorting the PSU. i would advise buying a electric air duster, like this one for example: https://www.amazon.com/XPOWER-Inflating-Detailing-Performance-Eco-Friendly/dp/B086WRHRSJ/ref=sr_1_11?keywords=electric+duster&qid=1687437114&sr=8-11

You used the Corsair psu cables for the MSI PSU?

 

Your not going to like this but i would suggest a rebuild to make sure any of the old PSU liquid you found is nowhere else in the case and clean it out regardless

 

Do not mess around (looking inside it)  with the corsair psu dispose of it safley and i would just use the msi cables for peace of mind.

 

As for the cause? Its very unlikley a PSU would blow up like that unless Gigabyte made it. Is the power source stable in your country? Lots of black outs?

PSU really blew up, pretty rare with Corsair RMx PSU !

They have a 5 year long warranty period, check if you can get a replacement (if you don't need it resell it)

 

Pls change all your cables they may not be really compatible and work for a time then melt or whatever, something  bad will happen

yes all cables didn't remove one of them just the Psu itself

yes i live in a very dusty environment

and yes i got one of those electric air dusters but hadn't cleaned it since a few months

didnt replace any cables

i checked for liquid and cleaned the bottom up

but will later replace them according to your suggestions

 

to be honest i tought all these cables are the same and just the psu itself is a different brand, my tought was all these custom made cables that get advertised have to work somehow so i guess all are same, but good to know then nothing happened again

I see, then I shouldn't even be that bad. I wanna clean my PC now XD. Yeah the issue is that the connectors is sometimes the same, but wiring is different.

so you guys scared me enough that i opened up the case and changed the cables of GPU, Motherboard and CPU but sata cables and peripherals i still left coudnt be bothered to be honest at least i have half of a peace inside of me now, atm everything works fine
