Therefore, the cause is likely tied to a bridge rectifier failing to properly convert AC to DC, or a MOSFET failing to chop voltage into pulses so it can be stepped down to the 12V, 5V, or 3V rails by the transformer. Either would lead to a short internally, which is why we saw sparks before flames in the footage. We can't confirm any of this, of course, especially because the video is so low-quality, but it's our best guess.

pjmelect I often repair power supplies and I have had my share of power supplies blowing up, but I have never seen one that was capable of blowing holes in the case of the supply. Reply
Dong1995 Your view is fair and objective. Unfortunately, many other media outlets and content creators distort or even fabricate information just to attract attention and traffic. This power supply is clearly not brand new. It has been resealed with tape, without the original factory seal or protective foam. It could be a defective unit or one that was previously opened and repaired, yet they are presenting it as a brand-new power supply that caught fire. My view is that independent media and content creators should report hardware-related information fairly and objectively, rather than distorting the facts. The manufacturer should also carefully investigate the product and determine what actually caused the incident. If the problem is on their end, they should address and correct it promptly. Reply
