Considering its price of less than $140, the Neopower 650W Blue represents a phenomenal value for the performance it provided right across all of our tests. At lower loads, it is the most efficient power supply we have ever tested even though its efficiency decreased as load increased. The voltage regulation and ripple suppression are beyond reproach and really highlight how well the Neopower can handle nearly anything you can throw at it.
