Overview
- A Taiwan PC owner reported smoke from an RTX 4090 after their cat’s loud meows drew them back to the room, according to a post on the PTT forum picked up by multiple tech outlets.
- The computer kept running and would not shut down, so the owner pulled the plug from the wall after seeing smoke and smelling burning plastic.
- Photos and the account describe a melted 16‑pin power connector that fused to the graphics card, preventing the cable from being removed.
- The user said they ran an MSI RTX 4090 Gaming Trio with an FSP HPT2‑1000M power supply using a direct 16‑pin connection without an adapter and claimed the plug was seated and checked regularly.
- Reporters note this is the latest in years of melting reports linked to the 12VHPWR design, where small pins and poor contact or uneven pin load can cause heat build‑up, and they reiterate common advice to ensure a firm seat, improve airflow around the plug, or reduce peak power draw.
