Angelbird Wings PX1 SSD Adapter @ techPowerUp
 

Angelbird's Wings PX1 adapter lets you install M.2 SSDs in the motherboard's PCI-Express slots. This approach unlocks full bandwidth for older chipsets. The adapter also comes with a nice metal heatsink that prevents thermal throttling on high-performance M.2 SSDs like the Samsung 950 Pro.
