Nvidia RTX 5090 Melts Riser Cable

The recent report of an Nvidia RTX 5090 melting a PCIe riser cable has raised concerns among PC builders and gamers. The incident, reported on Reddit, involved a Lian Li PCIe riser cable that was stuck against the backplate of an Asus TUF GeForce RTX 5090 GPU. The direct heat contact caused the riser cable's insulation to melt, resulting in material being chipped away and stuck to the GPU's backplate. This incident is not an isolated case, as there have been previous reports of GPU power cables melting due to high power draw. The RTX 5090, in particular, has a power draw of 575 W, which can lead to overheating and component damage if not properly managed. The use of riser cables is common in small PC cases, where larger GPUs need to be accommodated in a vertical position. However, this incident highlights the importance of cautious component selection and spacing to prevent overheating and damage. PC builders and gamers should be mindful of component compatibility and heat management to avoid similar incidents. The incident serves as a warning to be cautious when building or upgrading a gaming PC, especially with powerful GPUs like the RTX 5090.
