罕見發出聲明稿,但實際上問題還是得從根本的設計上進行改善。

NVIDIA GeForce RTX 40 系列導入的 12VHPWR 接頭在全球發生超過 50 例的熔毀事件,對此 PCI-SIG 在近日發出公開聲明,要求所有 PCI-SIG 會員採取一切適當措施,確保使用者的安全性。

在此公開聲明之前,NVIDIA 就因為 12VHPWR 接頭熔毀一事,在美國加州被使用者提告。

PCI-SIG 的完整聲明如下:

PCI-SIG wishes to impress upon all Members that manufacture, market or sell PCI-SIG technologies (including 12VHPWR connections) of the need to take all appropriate and prudent measures to ensure end user safety, including testing for the reported problem cases involving consumers as alleged in the above-referenced lawsuit.

Members are reminded that PCI-SIG specifications provide necessary technical information for interoperability and do not attempt to address proper design, manufacturing methods, materials, safety testing, safety tolerances or workmanship. When implementing a PCI-SIG specification, Members are responsible for the design, manufacturing, and testing, including safety testing, of their products.

聲明中可以清楚知道 PCI-SIG 並沒有針對熔毀事件做出任何正式回覆,但 PCI-SIG 發出類似聲明是相當罕見的事情。

就我們知道,PCI-SIG 協會成員已經針對 12VHPWR 接頭進行「Change Proposal」,這裡面主要是修改 Sense Pin 與 PWR Pin 的接觸尺寸,至於是否有幫助或通過協會成員的認可,這還有待後續觀察;此外,我們也確認 NVIDIA 已經要求 12VHPWR 接頭主要供應商 Astron 針對相關接頭進行修正,這次修正主要是改善使用者不易插到底,而讓接頭溫度升高將接頭熔毀的問題。
