I am looking to build a new budget pc, with a 7th gen intel cpu (probbaly core i3 7100 or core i5 7500) but cant seem to figure out the pcie lanes divison. ARK says, the cpu's have 16 lanes for use, while the H270 chipset has 20 and the b250 chipset has 12. I am curious that in the B250, will the motherboard cap the available number of pcie lanes from the cpu? And in the H270, will it be the cpu capping the motherboard instead?
Plus i read somewhere that the chipset reserves 4 lanes for sata and usb? Is this correct?
