So I added an EVGA GTX760 today, and instead of booting as normal, my PSU made about 5 clicking noises and then emitted a puff of white smoke. The clicks were about a half of a second apart and the hdd activity and power lights at the front of the case blinked with them. My build is as follows:
NZXT Phantom 410
NZXT Hue
5x Cooler Master Sickle Flow 120 mm fans
Corsair H100i
Crucial Balistix 8gb 1600 RAM
Asus z97-ar motherboard
Intel i5 4690k
PSU (emitted smoke) - EVGA Supernova 750b 80plus bronze
GPU (added today) - EVGA gtx 760 superclocked

After this happened I unplugged everything as fast as possible. I then tried to boot using a different power supply that I know works and nothing happened. The PSU that smoked then worked for another system without a graphics card. I was wondering if anyone has had something similar happen, and if so what did you do. I know the motherboard is done but do you think that the GPU, CPU, or RAM survived? Thanks so much.:(

Are you sure it was the PSU?

That's a great power supply.

I am sure the smoke came from the power supply. The problem might have been in the gpu but it was one of the two. The system worked flawlessly before the new gpu.

After further inspection and thought, it probably is the gpu because there is no signs of damage in the psu. Why would a GPU short out my system like this?

Is your power supply a B1 series or B2 , the great one is the B2 made by Super Flower.

If it's NOT THE B2 it could still be the PSU.

Even quality PSUs can fail. You could pull the GPU to see if it boots
but if you want to be safe you could disconnect all your components and do the "paper clip test" and voltage test it with a meter
