I have a 480watt Thermaltake PSU and a few months back I tried to boot my desktop but nothing would happen and then I smelt a very strong smell, that of hot metal. There weren't any sparks or noise just the smell of hot metal. I unplugged the system from the wall and have not dealt with the system til today. Is it likely the PSU is gone for good and do you think it may have affected any components in my system. My HDD is the most important in which I have files I need. I am currently about to take a old 420watt unit fromt the basement to temporarily use.
