New PSU not working

[Atoss]

I am having a problem with my new rig and it's PSU. To give you a little background, it's an AMD FX-6300 on ASRock 970DE3/U3S3 and a Asus GeForce GTX660 with factory OC. The first PSU I had was some cheap Chieftec, and I managed to kill two of those before I realised I should have gotten a better one. The next PSU was a 570W Gigabyte (bought it without any research, turned out that it would most likely be unable to handle the GPU). I used that just to confirm that the CPU and mobo weren't dead, and they were all OK. Now, the main problem - I bought a Corsair CX600 V2, which I had seen some decent reviews on, and by all parameters, seemed enough for the rig. I hooked it up (without the GTX660, I was afraid to kill it. Had an ancient S3 GPU in the PCI slot instead) and expected it to run. However, what happened was - the fans span for a moment, then stopped. All this time there was no output to the screen, and the power (I guess) LED was constantly on.

Any help on getting the machine running?

I'd say yank that S3 out and try booting with the Corsair unit. 500W is plenty for a GTX 660.

Also be sure to follow the sticky for troubleshooting:

The results I got: smoke, smell of fried silicon, and a dead GPU. Not exactly sure if I should have done that .
