I bought a Rosewill Power Supply from Newegg.com. It didnt work on my desktop despite being the same model as what I ran for little over a year. Tested it on another machine with only tower plugged in, turned right on. Got a new tower and plugged it in and it went out with a series of 5 pops. Destroyed over $760 worth of computer components and they refuse to cover the damages because they claim they are not liable. MOBO destroyed, RAM destroyed, Processor destroyed, Video Card destroyed. And they claim they are not liable because they did not install the Power Supply. DO NOT BUY FROM THESE PEOPLE!!!
