A few days ago, after adding in my 1TB drive, I turned my pc on only to see smoke and smell of burnt plastic. After I removed the HDD and cut the burnt cable, I waited 2 days and turned my computer on again. This is what I see. Now, I'm pretty sure that 12v is supposed to be around 12v. This is practically an entire volt higher. Should I replace the PSU, or is the voltage within some "safe range"?
