“When I was squatting in the toilet, I suddenly heard the cat keep screaming, and when I opened the door, I saw the smoke and smell of plastic,” the user explained.
While the cat’s alert likely prevented a worse outcome, the incident highlights an issue that has followed NVIDIA’s flagship GPU since launch.
The RTX 4090 has been plagued by reports of its 16-pin 12VHPWR power connectors overheating or melting under certain conditions. Investigations previously suggested that improper cable seating or uneven power distribution across pins could lead to dangerous heat buildup.



Not only that, but a cheap PSU can also fry your other PC parts due to power surges when it breaks.
