Hot plastic smell..?

[JDS]

So, I was doing what we in this forum do best, overclocking my 780 Ti. After getting my clocks to my desired speed, I ran Unigine Valley (which actually yielded me my highest score) and noticed about midway through, an odd odor. It wasn't like "something is on fire" smell, it was like "is something really warm?" Kind of smell. Anyhow, I quit Valley and the smell was gone. Then I tried to reenact the situation, wondering if it was just an oddity, well I smelled it again, but much less potent. The smell SEEMS to be going away, but I'm worried about my expensive toys. My temps never exceeded 78 degrees Celsius. My original thought was that my VRAM was cooking, considering I cranked those higher than I ever have, then I thought maybe my power supply was causing it...

What're your thoughts?

RMA it

THE END IS NIGH

 

Switch off the PC, take out the GPU and smell the motherfucker, if no returns come from that bloodhoud activity then begin sniffing other stuff (PSU) before the scent is lost.

 

Burning smells from the PC are a red flag.

Weird... a wire maybe? 

[dragoon20005]

give the PSU backside a sniff when you run Unigine

 

or take out the GPU and see if there are any melted parts

When I put my nose up to the rear exhaust fan of my PC I can smell the sadness from a chinese factory.

BUT IT'S SO YOUNG!

I'll see what I can do about the sniffing. I wanna say it's not my 780 Ti BECAUSE I didn't touch the voltages.

...and if it's not the GPU?

[dragoon20005]

i say it possible the glue on the coils in the PSU are the cause of the burning smell

 

 

smell the backside of the PSU where the heat is exhausting

@JDS as one of my posts and now 2 of this man's posts have said take a sniff of the PSU.

 

Y U NO do this lol

The only problem is that my Ti blows air back there too...

Like I said, the smell seems to be going away, so your theory would be correct in the sense that once it burns the excess off, it'll stop smelling.

the only concern is that with your GPU OC

 

you are putting stress on the PSU

 

which is why it gives off that smell

 

if it does go away, not so much of a concern 

 

but if the smell does stay, I will worry and get that PSU replaced

I inhaled as much as my lungs would allow. You should be proud considering burning plastic is a carcinogen...

Well have you found the source of the smell?

If I'm not upping voltages how is there more stress on my PSU?

[JDS]

I can't really say. It's definitely coming from the back, but that still leaves both the Ti and the PSU...fack.

more OC = more heat

 

more heat = more cooling

 

more cooling = more power

Touché. Unfortunately I have to be at work in 5 hours, so I must go to bed for now. I contacted EVGA and they said it could be some adhesive residue burning off, and if it still smells after a day or two to contact them. What other ways can I find out of it's my PSU? The smelling is inconclusive.

hmm i just did a quick google

 

CX600 are known to burn itself out and that smell the other user have and failing to boot up

try looking around for any other damaged parts

Open your case up and unscrew your PSU, put it somewhere away from your gpu and stress your system. That'll help you be able to tell where it's coming from.

You could take your psu out of your build (but leave it connected) and while running unigine hold the exhaust up to your face. That way you could seperate the air coming from your gpu und your psu to find out whats actually smelting.

That's the plan for tonight. When I'm home from work I'll be sure to give that a go.

Do we think 600 watts is enough for OCing a 780 Ti and a 4670k? If I'm drawing too much power from my PSU then I'm sure that's the problem, as already mentioned.

I'm running an i7 2600k overclocked and a GTX 780 overclocked on 500W... Made by OCZ... So you tell me if 600W is enough
