Hey. Because of first building my pc with radiator placements that fitted with a Gtx 670 when my Titan was sent back (rma, got Titan Black, back ), anyway the Titan don't fit the top Pcie and have to be in the second pcie. But I only get 8x and I thought that I would get 16x when running only one card? Sorry for my bad English.
Its a Mpower z77. http://www.msi.com/p...Z77_MPOWER.html
