So a few days ago, I was using my desktop when all of a sudden i heard a click sound from inside the case. Immediately upon clicking the computer turned off. I then smelled the lovely but horrifying smell of burning electronics, at which point I unplugged the computer. After I while I tried plugging it back in and seeing if it would turn on. It didn't. Pushing the power button did nothing. So, at this point I figure either the power supply is shot, or both the power supply and the motherboard is shot. Is there any way to determine which scenario played out short of buying/obtaining another power supply to test it with? Also the power supply in question is an Antec True Power Quattro 850W. I'm assuming a high end power supply like this should have some sort of protection, right? Thanks for any help. Also one last question. This particular PS was on the damaged rack at a local store. I bought it less than 3 months ago though. So is this something that would typically fall under warranty? Or am I basically screwed? I'm not quite sure on Antec's RMA/Warranty policies.
