Current Load
- 3.3V 最多走到 3A
- 12V 最多走到 5.5A
- 一支PCIE connector 最多走到 3.3V x 3A +12V x 5.5A = 75.9 -> 75W
- 150W: 75W + 12V x 6.25A (by 2×3 connector)
- 225W: 75W + 12V x 12.5A (by 2×4 connector)
- 300W: 75W + 12V x (6.25A+12.5A) (2×3 connector+ 2×4 connector)
Thermal Management
- 卡類分成一般卡與Adpter card，以下只針對一般卡
- 如果有自帶風扇，規格會以CFM標 (體積流量)，沒有自帶風扇則以LFM標 (流速)，Adapt card另外以AFI標 (Airflow impedance)
- 225W/300W的ambient temperature 建議在45C以下，其他則建議55C以下
- CFM 將ambient temperature定義為風扇進氣平均溫，LFM則定義為離卡1″ (25mm)遠處之平均溫
- 150W以上的卡都建議自帶風扇，直接將熱排出系統，不要共用系統風流
