On April 24, 2026, the renowned hardware repair outlet Northwestrepair posted a repair video for the RTX 4090 FE public edition, unveiling that NVIDIA had executed at least one PCB design revision during the RTX 4090's production run, where a chip initially included in early production batches was omitted in later iterations. The graphics card submitted for repair couldn't be powered on. After a thorough diagnostic process, the repair technician employed a thermal imager to trace the fault's origin to a small chip that was overheating near the memory power supply circuit. Upon further inspection, it was discovered that this chip was missing in newer batches of the public edition graphics cards, substantiating that NVIDIA had indeed revised the PCB design and removed this particular component. Ultimately, Northwestrepair procured a replacement chip from a Gigabyte graphics card and successfully restored the unit to working condition.
