I havn't paid attention to hardware for 5 years, now that I am planning to piece up a new computer, I realize there are many new devices which can greatly improve performance, M.2 SSD card being one of them. I spent several hours reading articles and comparing products on newegg about M.2 and conclude that among 3 choices of SSD(regular sataIII ssd, PCIe SSD, M.2 SSD which utilizes PCIe as protocal), the M.2 one has the highest price-performance ratio. And I am aware that to make the best of my M.2 PCIe SSD, I need to make sure the motherboard supports it. However, when I look at the motherboards' specifications, many of them usually don't mention whether the M.2 supports PCIe or not, like this one.
So the question is, how do I find out it?

Well, the M.2 standard is a small slot, about half the width of a playing card, or stick of laptop RAM. If you look at this image here:

Note the connections on the bottom right (Boxed in Red) This is where your M.2 card usually is inserted. Depending on the length of the m.2 card, it will screw into one of those four screw holes, as it mounts at an angle from the board and is pushed down until it lies on the same plane as the motherboard, and kind of "floats" above the board if you will. When you're looking at a motherboard, look for this distinguishing feature/ features. Often times it will be located either below the chipset heatsink or next to/in between the PCI-E slots on the motherboard

Hope this helps.

EDIT: For reference, here is an image of an M.2 SSD being slotted into the motherboard:

Thank you for your answer Sir. But I am not asking whether my motherboard support M.2 or not, insteadly, I am asking how to find out whether the M.2 on the motherboard supports PCIe or SATA.
