So I left home Saturday night with my computers turned on, as I normally leave them. Sunday morning I returned and saw one of them off and the other one on. I thought it was a little strange I shrugged it off and went to turn the computer back on. I heard a very loud pop when i hit the power button but didn't really smell any smoke. I put my nose to the PSU fan but I'm not sure if I could smell anything. It may have been a residual burned smell or it may have been the smell of newness coming from my Enermax Liberty 620w PSU. The PSU is less than 4 months old. Either way does anyone have experience with PSU's making a poping sound? Is this PSU done for and if you have experienced this in the past did it take out other components as well? The computer does not turn on atm.
