2x6pin vs. 1x8pin pci-e Tags: Graphics Cards Cable PCI Express Graphics Last response: April 11, 2012 9:01 PM in Graphics & Displays Share numitors April 11, 2012 7:58:47 PM Hi, Is there any particular reason why all graphic card that need between 150W and 225W (so they need 150W over additional cable beside 75W from pci-e slot) always use 2x6pin and never 1x8pin? Wouldn't it be more compact that way?

The dual 6-pin configurations are likely just for compatibility since 8-pin is fairly new many Power Supplies don't have it yet. There are adapters to attach an 8-pin PSU cable to a 2x6-pin graphics card. 8-pin will replace dual 6-pin eventually. numitors April 11, 2012 8:59:47 PM Thanks for the answer. The reason I asked is because I read that 6-pin provides 75W and 8-pin 150W of power so i thought that one 8-pin would be same as 2x6-pin. Can't find your answer ? Ask !
