I have no idea why the wattage is rated so low because the specifications from Molex clearly allow substantially more power. Part of the reason may be that pin 2 (listed above as a 12 volt line) may be listed as not connected in the specification. |

They state the 6-pin PCI-E power connector should theoretically be able to output more than 75w. This along with the fact that the 8-pin PCI-E power connector still only has 3 +12v lines but can output 150w makes me believe that the bolded text above could certainly be true. If it's true that the 75w specification is only using 2 +12v then the 3rd very well could have just been extra headroom like andynolife stated above. |
