早前被大家熱議的 NVIDIA RTX 4090 顯示卡接頭 (12VHPWR) 接頭燒燬事件終於有官方回覆了，NVIDIA 正式發表聲明：「主成因是接頭沒正確連接所導致。」
NVIDIA 在聲明中提到全球有 50 起相關的案件，主因來至於顯示卡端的電源線接頭沒有正確的插入插座當中，導致電阻升高、溫度急升，當溫度超過插頭材料的燃點後則開始冒煙、融化接頭。
另外早前曾推出過 90 度轉接的 12VHPWR 接頭廠商 Cablemod 也提供了 12VHPWR 接頭的安裝指南，以降低用家因安裝不良導致接頭融化的機會。
We are actively investigating the reports. We are aware of about 50 cases globally.
Our findings to date suggest that a common issue is that connectors are not fully plugged into the graphics card. To help ensure the connector is secure we recommend plugging the power dongle into the graphics card first to ensure it’s firmly and evenly plugged in, before plugging the graphics card into the motherboard.
We are investigating additional ways to ensure that the connector is secure before powering on the graphics card.
NVIDIA and our partners are committed to supporting our customers and ensuring an expedited RMA process, regardless of the cable or card used.
另外 NVIDIA 方面，也提到正在研究其他方法判斷電源線是否有正常插入，同時指各顯示卡品牌也會盡責處理因接頭融化燒毀的顯示卡 RMA 保固。
