Burning smell coming from the case after installing a brand new GTX 650

As the title suggests, I installed this GPU and got the weird smell. I checked it for stability and temperatures in furmark and it never went above 65C. Could this be a PSU problem? I have 400W PSU and here's my non-power hungry build:

Intel i3-540 not overclocked (this chip is about 4 years old)
Samsung HD 120IJ
Asus P7H55-M LX
2X2GB Hyperx blue

  1. What brand and model of PSU?
    "weird smells" are not good
  2. ALFA P4-400W ATX
    230V-50Hz/60Hz 3A
    +5V -5V +12V -12V +3.3V +5VSB
    16A 0.5A 21A 0.5A 17A 2.0A

    It might very well be the PSU: Cheap units usually fail to deliver their rated output so the new card may be overloading it. I think a replacement would be a VERY good idea...Look for 450-500W from Corsair, Seasonic, Silverstone, XFX, EVGA, Antec or FSP.
    The other possibility is that the new card is just settling in, most cards will give off a sweet 'metallic' smell when new, in which case it will go away after a few days.
    according to this site you are barely ok, but even if you weren't I'd wouldn't expect a burnt smell unless it is really a horrible PSU with no protection whatsoever (they are known to exist). Try really hard to locate the smell, who knows what's up?
  5. 21 amps? that is only 252 watts on +12

    Not good at all for a "400w" PSU
  6. Hey, thanks for your answers! I just noticed that the smell is coming directly from the PSU. That must be it then, I must find time and money to buy a new one. In the meantime do you think I should remove the GPU and switch back to the integrated graphics?
  7. I would, otherwise you are risking blowing things up.
  8. Did you get a new PSU and if so, how's it going?

    I hope you don't mind me asking, it's just that I've had exactly the same problem and the PC I've been using has a GTX 650 with a 500W PSU. Actually I checked the recommended minimum electric power for the PSU and it came back as 500W (even more if I have a device or two I'm unaware of (I'm a noob on PC hardware)). I have been told that PSUs which only meet the minimum power requirements can have problems.

    Here's a link to the question I asked about it on
