Gaming mobo and M.2

[magician777]

Hi Guys, I hope someone can help me out here.
I have an MSI Z170A Gaming M7 motherboard,
I have 2 msi 970s gtx gpu = SLI
I would like to install a

“HyperX Predator PCIe Gen2 x4 (M.2) Internal SSD - 480 GB”

however will this in some way effect the GPU abilities, not enough slots or what ever ….
I read on the mobo PDF that gpu will be 8 and 8, PCI-E 2 and 5.
the HyperX Predator PCIe Gen2 x4 (M.2) is a four which M.2 slot will this be fitted in to on the mobo to get the full speed, I.e x4...
There are lot's of picture options, it's a bit confusing
any help would be appreciated

Regards
Gary

A Skylake CPU with a Z170 board has split PCE-E lanes with 16 lanes coming from the CPU only for use by graphics cards and 20 coming from the Z170 chipset for anything else. So using an M.2 drive should not be affected by your GPU's which should be working at x8 speed as there are splitting the 16 lanes from the CPU. The m.2 drive will take its lanes from the pool of 20 coming from the Z170 chipset...

Look at the Z170 chipset layout diagram part the way down the page....
