The previous AX generation was based on Seasonic's KM2 platform. The new AX units are still made by Seasonic, but they utilize the fresh KM3 platform that houses many improvements over the older one which, by the way, is still a solid performer. Below, you will find a short list of those improvements, which you will probably find pretty interesting.
12V Line regulation is ?2% instead of the ?3%
Flat, Black DC Cables
Easier for system builds
Looks match current chassis internals better
Better for airflow in system
Increased number of possible CPU/PCIe cable options
KM2 had, on the PSU side, 2x12Pin + 1x8Pin connectors for the CPU & PCIe cables
KM3 has 5x8Pin, which offers extra cable options
KM3 is Full Bridge as compared to KM2's Half Bridge
Improved reliability and efficiency
MOSFETs on daughter card instead of main PCB
Improves space utilization on main PCB for safety and cooling
Allows for increase of the ground-pad size on the main PCB, which improves efficiency
9A, 85?C high-current connectors
Added security and reliability
