THG這邊會解釋更清楚..其實規範是規範..
不光可以由6pin這邊抽電..還可以透過PCI-E抽主機板的12V的

AMD’s Radeon RX 480 draws an average of 164W, which exceeds the company's target TDP. And it gets worse. The load distribution works out in a way that has the card draw 86W through the motherboard’s PCIe slot. Not only does this exceed the 75W ceiling we typically associate with a 16-lane slot, but that 75W limit covers several rails combined and not just this one interface

他由PCI-E slot 多抽了11W的電

下面的論述再看下去就更精采了...

這邊加碼gtx1080的情況

mb上的印刷電路很細,給PCI-E slot供電的12v才3pin,
要撐75w已經很吃力,
看THG的這份數據,PCI-E slot的供電量不能用平均值的80w去算,要看常態性超過110w才對,
注定rx480完蛋了,甚至會連帶造成mb的不良影響。

原來 rx480 4gb不是想搶大量市場才開價 199usd,而是只有賣 199usd的資格。
在我看來,這東西必須降頻跑,頂多只值150usd。
