A Look Inside & Component Analysis













  1. 12V Line regulation is ±2% instead of the ±3%
  2. Flat, Black DC Cables
      3. Easier for system builds
      Looks match current chassis internals better
      Better for airflow in system
  3. Increased number of possible CPU/PCIe cable options
      4. KM2 had, on the PSU side, 2x12Pin + 1x8Pin connectors for the CPU & PCIe cables
      KM3 has 5x8Pin, which offers extra cable options
  4. KM3 is Full Bridge as compared to KM2's Half Bridge
      5. Improved reliability and efficiency
  5. MOSFETs on daughter card instead of main PCB
      6. 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
  6. 9A, 85°C high-current connectors
      7. Added security and reliability
