It's AZ370-Gaming (1458:a0b8), and fortunately it was already supported in 4.12-rc. Try the kernel in OBS Kernel:HEAD later, which was upgraded to 4.12-rc3 yesterday. Note that it will allow the driver loading, but some outputs (either front-panel I/O or the rear I/O) won't work as is. You will need to create a special UCM profile for PulseAudio.
