- This power supply is designed specifically for the EVO D300v and Presario 4700 Series Desktop System, so be sure to check compatibility before purchasing.
- The 70% efficiency rating means that 30% of the power drawn from the wall is lost as heat, so consider a higher efficiency power supply if energy efficiency is a concern.
- The single fan cooling system may not be sufficient for high-performance systems, so additional cooling may be necessary.
