Put a fork in it and buy another one... not a Diabotech. A new PS. It had a three year warranty if you want to play with the company. But the reviews of this supply are 39% five star and 33% one star.
I'd go with an Antec, Corsair, Thermaltake, Seasonic, Coolermaster or Rosewill.
Good news is that you bought a single rail supply, so 90% probability you didn't damage your MB or components.
You should spend at least $50 US and get a Single rail 80+ Bronze supply at a minimum and use an UPS to protect it.
