    Molex Mini-Fit Jr – Know your Power, and Don’t Get Confused – “PCIe” and “Xilinx Not PCIe” Power Connector

To move packets you need power, but how much can you draw from an interface? PCI Express Cards Consumption Limit PCIe has been around for a long time, since 2003, and many people know the maximum power draw of 75W per PCIe slot, but is it that simple? The short answer is no, but let’s have a look into the spec. It states that all cards can consume up to 3A on the 3.3 V power rail with the following restrictions applying: x1 cards: 0,5A on 12V, but overall consumption limit is 10W x4 – x16 cards: 2,1A on 12V, but overall consumption limit is 25W  But
