</h2><p>与CPU供电的做法相同，现在独立显卡已经不仅仅是从主板插槽上取电，为了满足GPU对供电的高需求，现在主流或以上级别的显卡大都需要使用外部供电，而这个供电接口则是大家熟悉的PCI-E供电接口，主要是有6Pin和6+2Pin两种。</p> <p><img

class="gallery-image" data-flex-grow="267" data-flex-basis="641px" ></p> <p>PCI-E 6+2Pin供电接口本质上就是8Pin供电接口，同样是分离式和整体式的区别，不存在性能上的差异，仅仅是出于兼容性和多用性的考虑，因此现在电源上基本只有6Pin和6+2Pin两种PCI-E显卡供电接口。PCI-E供电接口 主要提供+12V供电，其中PCI-E 6Pin供电有2组+12V供电，而PCI-E 6+2Pin则有3组+12V供电，一般而言每组能承担8A供电，因此PCI-E 6Pin供电的最大输出功率为192W，而PCI-E 6+2Pin的有288W。</p> <p>然而这是PCI-E 6Pin以及PCI-E 6+2Pin接口最大传输功率的物理值，并不是PCI-E规范中的限定值。实际上按照PCI-E规范的要求，单个PCI-E 6Pin的供电功率不得大于75W，单个PCI-E 6+2Pin/8Pin的供电功率不得大于150W，这些规范中的数字都远小于接口的实际物理上限。</p>
