Finding a Mobo for I7 that supports M2 in PCi

Hello all, im trying to find a good mobo for I7 that supports M2 in PCIe and NOT sata. All the motherboards i've looking at arent clear, but they give the generic m2 support nod(could be sata, could be pci). Is there a way to be clear on these mobos, or do i have to call the companies and ask directly or something?

Here is the list of things im wanting to upgrade with. I have all the other parts already.

More about finding mobo supports pci
  1. The Gigabyte GA-Z270P-D3 has one M.2 connector that supports both PCIe Gen3 x4 & SATA SSD devices.
  2. I saw that, but thats not clear. Of course it supports M2, it just doesnt say how. So a DRIVE that are pcie or sata capable can be used, but it doesnt say which bandwidth the port is actually using. That i get this while on my compatibility warnings on pcpartpicker;

    "The motherboard M.2 slot #1 shares bandwidth with a SATA 6.0 Gb/s port. When the M.2 slot is populated, one SATA 6.0 Gb/s port is disabled."
    This means that port is using sata, doesnt it?
  3. Or does this (M.2 connector that supports both PCIe Gen3 x4 & SATA SSD devices.) mean that it supports PCIe up to X number of drives, then uses sata?
  4. I see what your asking now. I was confused by this at first myself. Although i still think their chart is confusing, in any case look at page 15 of the Gigabyte GA-Z270P-D3 motherboard manual.

    1. If you install a Sata SSD into the M.2 slot, the port labeled "SATA3 0" on your motherboard will no longer work. Any drive connected to that port will no longer be seen in Windows.

    2. If you install a PCIe SSD [NVME] into the M.2 slot, all the Sata ports will still work. Since PCIe SSD's use different lanes than Sata drives they are not affected by that limitation.

    This is why a Sata SSD can still only run up to the usual 6Gb/s limit, even if it's in the M.2 slot. Only more expensive PCIe SSD's can use the full M.2 bandwidth.

    The Intel chipset will only support up to 6 Sata devices whether they are connected to the older Sata ports or the newer M.2 slot. AMD B350 chipsets will only support up to 4 Sata devices. Any Intel or AMD motherboard that has more Sata ports than the chipset will natively support, is using an add-on chip by Marvel or JMicron to run the extra drives.
  5. So, assuming i have the appropriate M2 stick, this mobo should support the 4x PCIe for my m2? The M2 drive i have right now isnt the correct stick?

    Also, Ill have 1 or 2 other regular sata SSD's installed as well.

    Thank you for your help, i really appreciate it. This has been crazy frustrating.

    The SAMSUNG 960 EVO NVMe PCIe 3.0 x4 SSD will use the full M.2 bandwidth. It is as labeled "NVMe PCIe". [PCIe 3.0 x4 = PCI-Express Generation 3, 4 lanes]

    You regular SSD's will work as long as they are not plugged into the Sata port labeled "SATA3 0".
  7. You rock my friend! Thank you so much!
