I just recently installed a new EVGA GTX 780 ti inside of my gaming PC and I'm getting a strange smell from my case but only during the first 4 minutes of gameplay. Then the smell goes away. I monitor my computer CPU's and GPU's temps like an eagle. My CPU and GPU temps always stay below 72 degrees as long as I have Vsync turned on. I am using a temporary 600watt GPU because my primary one went bad. This back up PSU was kinda dusty before I took an air compressor to dust it out. But I could not get all the dust.

EVGA phone support told me that I have enough watts from my back up PSU but I will be replacing it very soon.

Do you have any idea why I might be experiencing this strange smell?

Something is burning, from your description sounds like it is something close to a heat producing component and starts to burn quckly, but once something else nearby gets hotter (assumption) the PC increases fan speeds to $part and it keeps the temps low enough that the burning stops.

With all the new parts (and admitted amount of dust in the PSU) it would be hard to narrow down exactly where the smell is coming from... but you could try to remove the PSU from the case while keeping the MB/GPU/HDD plugged in and see if the smell comes from the PSU or the case.

Umm, smell the air being blown out of the PSU - if it isn't in the case and smells of burning - there is your problem.

I didn't say to stick your head into the case and get within an inch of the motherboard. Just isolate the PSU (as the most likely culprit) and see if it is blowing smoke.

I pulled the PSU out while it was still connected to everything and ran a quick benchmark test. Although the smell was less apparent it did help me to believe that the smell's most likely culprit was my PSU's fault as the same smell was still there even though it was less apparent being out in the open air like I had it. Never the less still there. I have horrible luck with PSU's. Thanks for the suggestion "Menetlaus", that was a good idea. Sometimes the simple answers are the best answers! Cheers!

Just waiting for my new PSU to show up in the mail and trying not to punish the one I am using now.
