Nvidia’s RTX 5090 received glowing reviews at launch because of its explosive performance, with many citing its FPS-crunching numbers as what young people would call “fire.” Unfortunately, to extract that kind of performance, the card pushes a lot of power through a connector notorious for its tendency to melt. We’ve just seen the latest case of a 5090 reportedly catching on fire, and it did burn, but this time the situation is a bit different than what you might think.
A Taiwanese Gamer.com.tw forum thread, first spotted by UNIKO’s Hardware, tells us the tale of a Zotac RTX 5090 AMP Extreme that allegedly caught fire mid-game during a Battlefield 6 session. The original poster, york4517, says the machine was a store-bought NZXT prebuilt. While playing Battlefield’s open beta, the screen suddenly froze, a flash and burning smell appeared, and that’s when the user noticed a flame inside the PC. The fire, coming from the GPU, lasted roughly ten seconds and left the 5090 heavily charred. The motherboard and SSD were also damaged, and even the liquid-cooling tubing smoked black.
The photos attached in the forum post show concentrated scorching around the lower edge of the PCB where the card meets the motherboard. Uniko pins the origin of the fire to the MSVDD rail—the memory-subsystem power line—and suspects a MOSFET short or phase failure in that area likely caused the burn, noting that section had no dedicated cooling. The pattern in the photos suggests a rapid, localized power-delivery failure that arced and burned through traces and nearby components, so the card appears to be a total loss.

Nvidia RTX 5090D falls victim to infamous 16-pin melting issue
The RTX 5090 is no stranger to failures, and this just adds to a long list, including an Asus ROG Astral 5090 with a suspected capacitor or VRM-phase blowout that scarred both card and board while leaving the 12V connector intact, and multiple reports of 16-pin / 12VHPWR connectors melting or showing severe heat damage despite seemingly being properly seated. This time, though, we cannot entirely rule out user error, as the card was confirmed to be undervolted first. But that’s nothing extraordinary and certainly doesn’t set the stage for the GPU to burn up.
