I am aware that it is my power supply for many reasons because my almost 2 year old 480w PSU was powering a 660 Ti and I smelled the PSU and it smelt burnt! I just ordered my power supply and am curious to how likely my other components (Mobo, GPU) are to have survived. I unplugged my PSU and turned it off within 5-8 minutes after it died. I would really hate to have to buy another Mobo and or GPU. The PSU was an Artic 480w with my computer being turned on 85% of the time for about 1 3/4yrs. So if you could answer the likelihood of my other components to go out I would much appreciate it. I am a novice computer "builder" and have never had a power supply go out.
