ATC-780A-UR12 M.2 Interface - SATA III or PCIe x4?

Acomp

I am primarily looking to determine if the interface for the available M.2 slot (which I believe to be 2280 size with an "M" key) on my ATC-780A-UR12 is SATA III or PCIe x4 (or perhaps both?).

 

Also, I read on https://www.kingston.com/us/ssd/system-builder/m2_faq that sometimes "the M.2 SSD socket could share PCIe lanes or SATA ports with other devices on the motherboard" and it reccommend that I "review your motherboard documentation for additional information as using both shared ports at the same time could disable one of the devices."  Is this an issue for the ATC-780A-UR12 motherboard?

 

Finally, more generically, information regarding all of the moterboard slots/specifications would be useful (i.e., a motherboard manual would be useful).

 

Thanks.

Hello,

 

Here are the specifications of this M.2 socket: PCIe 3.0 X2 or SATA 3.0

But all original M.2 2280 SSDs are SATA 3.0.
