端口集成温度传感器
guru3d新闻稿：
Power supply manufacturers have recently been addressing issues related to the RTX 50’s power distribution. The main technical challenge involves an uneven load across the pins, which can lead to overheating and even connector damage. In response, some companies have introduced cables equipped with temperature sensors. For example, FSP has developed a 12V-2×6 cable that incorporates a thermistor. This sensor monitors the temperature in real time at the GPU connector, and if it reaches around 110°C, it triggers an automatic shutdown of the power supply.
However, this solution comes with some limitations. The sensor in the new cable only measures the temperature at the GPU connector, leaving the power supply unit (PSU) connector unmonitored. As a result, even though the GPU may be protected from thermal damage, there is still a risk that the PSU connector could overheat and possibly melt. This partial protection means that while the new design can reduce some risks, it does not offer a complete safeguard for all components. With systems like the RTX 5090 and RTX 5080 potentially being affected, industry experts are cautiously evaluating these developments. They are considering whether the solution could inadvertently lead to unexpected shutdowns or other issues in high-performance configurations.
Looking forward, it appears that more manufacturers might consider integrating similar sensor-based protection into their power supply cables. Although this approach represents a proactive attempt to mitigate overheating issues, it is clear that a comprehensive solution will likely require additional measures.

电源制造商最近一直在解决与 RTX 50 的配电相关的问题。主要的技术挑战涉及引脚之间的负载不均匀，这可能导致过热甚至连接器损坏。为此，一些公司推出了配备温度传感器的电缆。例如，FSP 开发了一种集成热敏电阻的 12V-2×6 电缆。该传感器实时监控 GPU 连接器的温度，如果温度达到 110°C 左右，就会触发电源自动关闭。
然而，这种解决方案也存在一些局限性。新电缆中的传感器仅测量 GPU 连接器的温度，而电源 (PSU) 连接器则不受监控。因此，即使 GPU 可以免受热损坏，但 PSU 连接器仍有过热甚至熔化的风险。这种部分保护意味着，虽然新设计可以降低一些风险，但它并不能为所有组件提供完整的保护。由于 RTX 5090 和 RTX 5080 等系统可能受到影响，行业专家正在谨慎评估这些发展。他们正在考虑该解决方案是否会在无意中导致高性能配置中的意外关机或其他问题。
展望未来，似乎会有更多制造商考虑将类似的基于传感器的保护功能集成到电源线中。虽然这种方法是缓解过热问题的积极尝试，但显然全面的解决方案可能需要采取额外措施。 |
