Nearly 2 and a half years ago, I started building a PC, nearly complete when life happened and that stopped. I parted some things out for money. What i have left is the case, the motherboard and the PSU. I'll be getting a new MB but my question is about the PSU. It was sitting, installed in the S340 elite, in the basement storage of my apartment for the last 2 and a half years. Clothing that was sitting beside it for the same time period were thrown away for mildew when i moved a month ago. Would this still be safe to use? The PSU in question is a Seasonic SSR-750RM never used.
