Amazon isn't the most reliable source; contact MSI if you want to be 100% sure. The PRO 1600 (YD160BBBM6IAE) requires a newer BIOS revision, but in your post you specified the 1600, not the PRO 1600.
I searched Amazon (.com, .ca and .uk) and I found people who had issues with newer processors like the 1300X, but MSI indicates that BIOS A4 is required; therefore such reviews can be ignored.
I found reviews like "Decent Board. Had to reset the CMOS to get it to recognize the RYZEN 1600. If you get a blank screen, do the same. Follow the directions in the manual on how to do it. 4/5 stars for advertising RYZEN but needing an extra step that isn't well documented to get it working." Several reviewers also mentioned they had to upgrade the BIOS to improve system performance and memory compatibility, but none mentioned the RYZEN 1600 didn't work.
