My motherboard AX370-Gaming K5-CF has 2 Sata Express ports as depicted in the manual in page 17 between the normal sata ports.

On top of the ports it says "Lotes"
I was wondering what cable fits in there. I bought a standard esata cable online but it's double the size this port has. The cable I bought is this one but it's double the width. Like a normal sata cable whilst the port is half the size
