Burning plastic smell from pc

[JamieF]

Earlier today I noticed one of my hds were not showing after upgrading to Windows 10 so I opened my computer and checked the power connector and it was unplugged, easy enough. Later I noticed a burning smell coming from the computer. I've never smelt it before but it was very strong. So I shut it off and opened my computer again, I figured it would just be a cable touching something and burning since my cable management is terrible, so I fixed it and closed it up again. That was about an hour ago. I switched it back on and after a while it started smelling of burning again. The smell is coming from inside the case because the smell is coming from the fan pushing air out of the case. But when I touched the back of the psu (outside the case) it felt extremely hot and smelt of burning too. Someone also had a look and said it smells like its coming from the back panel as well as the psu and fan. Time for new power supply?

 

Specs:

 

4770k

gx 660

550w Fatal1ty psu

26gb ram

2 hds (had 3 but removed one today)

 

Thanks.

 

Edit: When I switched it back on after fixing cables temps were normal.

Get a new PSU ASAP, that thing is about to blow

[Knaj]

Take out the PSU and plug it in, disconnected from your computer entirely. Turn it on, and if it smells, theres your problem

 

EDIT: Do this insanely quickly and in a safe place. If it is the PSU disconnected it ASAP and get it out of the house.

[TheAmazingCookieFromSquare]

Yo change that psu As Soon As You Can before your house burns down.DON't TURN YOUR COMPUTER ON WITHOUT PSU CHANGE IM WARNING YOU.

And yeah, be very careful with it and do your best not to inhale ANY fumes. And after you do what I said and it is the PSU, get a new one ASAP and put the old one out in a safe place where if it did start a fire it wouldn't do any damage, or not much at all.

 

But yeah, probably is the PSU

[JamieF]

Thanks for the help Any suggestions on new ones? going to be upgrading graphics cards soon.

Seasonic or XFX

GS 550/650W would be fine, most of the time it's around the CX price range but has better build quality and higher power efficiently.

Alright thanks, i'll have a look

[JamieF]

Quick update, turns out the psu fan had jammed some how and thats where the overheating and burning came from. Gonna buy a new one and send this one back under warranty

[Bordermick]

I have a rule when I build PC's that I feel everyone should follow, Never cheap out on the psu.

 

The PSU you got isn't too bad though Probably just a defective unit

[monaka25]

ASRock Makes PSU'S? Well that would've matched my motherboard.. but it isn't as reliable as my CX600M(I bought refurbished, nothing wrong ). BUT JUST, IF I HAD THAT ISSUE, I WOULDN'T DARE TURNING MY COMPUTER BACK ON.

 

BUY

 

A

 

NEW

 

POWER

 

SUPPLY

 

PERIOD

 

I say maybe a 800W psu for upgradability, and depending on how big your GPU upgrade is. I say something like a CS750M psu 80+ Gold, modular, and 750 WATTS, and from a good brand Mines a CX600M, modular, 80+ Bronze, 600w
