Ouch! Terrible to hear, hopefully ONLY the PSU was damaged! Ultra does have a quick RMA service, but they like to charge you card while they wait on the faulty one to arrive, but sometimes they ship out a new one with no hassles.
Please try to find a friend or family member, who will let you test or test for you, so you can test your CPU and memory to be sure they did not get fried. Also, if you can test your board somewhere too just to be sure it's OK
