电源升级解决了本地 LLM 用户 GPU 断开连接的问题

Reddit r/LocalLLaMA 子版块的一名用户发现,一个持续存在的 GPU 断开连接问题,最初怀疑是 PCIe 延长线、Oculink 线缆或 GPU 本身的问题,实际上是由电源单元 (PSU) 供电不足引起的。尽管使用了信誉良好的 450W 电源,但在加载 AI 模型和传递提示时,系统仍会崩溃,并显示“GPU 已脱离总线,设备已从总线丢失”之类的错误。通过升级到 550W 电源解决了该问题,这表明供电不足是根本原因。 AI

影响 确保运行本地 LLM 的稳定硬件配置,防止崩溃并改善用户体验。

排序理由 用户级别硬件故障排除建议,用于运行本地 LLM。
