Excellent mother-card socket 1155 of the old generation. Too many PCI-E over my use for now (I have a graphics card), connection quite well thought not to have slots blocked by the hardware, but suddenly it takes a little to quibble SATA connections "on the side". everything is there, even a USB connection for connecting the 3 USB3 eventual housing in addition to those on the motherboard. Content of this purchase P7H68 replacing one who lost the primary PCI-e
