</h2><p>與CPU供電的做法相同，現在獨立顯卡已經不僅僅是從主板插槽上取電，為了滿足GPU對供電的高需求，現在主流或以上級別的顯卡大都需要使用外部供電，而這個供電接口則是大家熟悉的PCI-E供電接口，主要是有6Pin和6+2Pin兩種。</p> <p><img

class="gallery-image" data-flex-grow="267" data-flex-basis="641px" ></p> <p>PCI-E 6+2Pin供電接口本質上就是8Pin供電接口，同樣是分離式和整體式的區別，不存在性能上的差異，僅僅是出於兼容性和多用性的考慮，因此現在電源上基本只有6Pin和6+2Pin兩種PCI-E顯卡供電接口。 PCI-E供電接口 主要提供+12V供電，其中PCI-E 6Pin供電有2組+12V供電，而PCI-E 6+2Pin則有3組+12V供電，一般而言每組能承擔8A供電，因此PCI-E 6Pin供電的最大輸出功率為192W，而PCI-E 6+2Pin的有288W。</p> <p>然而這是PCI-E 6Pin以及PCI-E 6+2Pin接口最大傳輸功率的物理值，並不是PCI-E規範中的限定值。實際上按照PCI-E規範的要求，單個PCI-E 6Pin的供電功率不得大於75W，單個PCI-E 6+2Pin/8Pin的供電功率不得大於150W，這些規範中的數字都遠小於接口的實際物理上限。</p>
