A few days ago I bought and installed a new power supply (http://www.newegg.com/Product/Produ...9005&cm_re=corsair_650-_-17-139-005-_-Product). After turning on the computer and verifying it worked, I leaned over the case to tighten the case screws, inevitably breathing in the exhaust from the power supply. It had a metallic smell. The next morning I had a slight cough. Today, the cough has gotten worse. I don't feel sick, but I have a moderate dry cough. Do you think this could be caused by the power supply? Or is it just a huge coincidence?
