ATX12VO規範完全取消了傳統的5V、3.3V，只保留12V輸出電路，由它統一負責為主板、顯卡、硬盤、外設等進行供電， 同時24針主供電接口改為10針，通常在CPU插座附近的4針EPS輔助供電接口則改為可選項，甚至是用於保持USB設備供電和喚醒的5VSB(Standby)輸出也改成了12VSB，當然USB輸出電壓依然是5V。 12V向其他更低電壓的轉換則全部交給主板負責，比如硬盤、固態盤、光驅等所需的5V輸入，都從主板獲得，為此SATA接口旁邊會增設一個SATA供電接口。</p> <h2 id="主供電接口main-power-connector10針定義">主供電接口(Main Power Connector)10針定義 </h2><p>線材推薦使用18 AWG,每個引腳需要支持8A的電流。 10針接口總共可以提供216-288瓦的電力，每個針腳6-8安的電流。</p> <p><img src="https://knightli.com/2022/05/26/%E8%8B%B1%E7%89%B9%E5%B0%94-atx12vo-%E6%8E%A5%E5%8F%A3%E5%AE%9A%E4%B9%89/1.png" width="1071" height="399"
