pretty much anything that at least supports PCI-e Gen 3 at x4 link.
which is z77, z87/z97, z170, and the HEDT platforms of x79 and x99.
most of the older platforms like z77 (first intel mainstream with native PCI-E 3) you run the m.2 in an adapter card and put it into one of the PCIE slots thats Gen 3 and linked to the CPU, not the chipset which is limited to Gen 2 speeds.
The newest z170 chipset is the only one that can support the full speeds straight off its chipset lanes since it can support Gen 3 speeds, having 20 PCI-E lanes vs only 8 PCI-E lanes of Gen 2 speeds in older chipsets.
x99 may only have the older chipset features in that its still 8 lanes of Gen 2, but it does have 40 or 28 lanes of Gen 3 straight from the CPU itself, depending on if you either have the 5960x/5930k or the 5820k.
