RTX 4070 Burned Out Right in PC — Due to Low-Quality PSU Without Protection
On the YouTube channel DIY Repair Hour a video of the demonstration has appeared a badly burnt RTX 4070 graphics card from Palit. Unlike cases of fire caused by external factors, this GPU burned right inside the working PC — the culprit was a power supply without overcurrent protection (OCP), which allowed the fire to spread.
The channel's author, software developer and enthusiast Patrick, reported that the card was used with a power supply previously used for mining. It was the lack of protection that allowed 12V HPWR power connector overheat to the point of catching fire. The owner said he was alerted by a "terrible smell" and then turned off the system.
According to Patrick, the fire originated in the area of the power connector, which again raises questions about the reliability of NVIDIA's new compact 12V connection. However, the main culprit lies with the use of an uncertified power source.
Despite the serious damage, GPU- the chip remained "alive" - Patrick tested it with a multimeter. Among the components saved were also memory modules, VRM, ports and even BIOS. However, the functionality of the entire card can no longer be restored.
This incident highlights the importance of choice quality power supply and proper assembly - after all, even the latest video card can become a victim of saving on basic safety.
