The story originally surfaced on a Taiwanese forum similar to Reddit, before being picked up by tech outlets.

“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.

this was not the case, but it is important to know this

i always use an external voltage regulator box too, it's been a must for me since the 90s

i think so, sorry if there is misunderstanding, 'voltage regulator' is just the literal translation i could make from how we say it in spanish

So would an UPS fulfill this role?

No, I'm just asking, in general.
