Performance, Noise and Efficiency
The ION+ achieves high-enough overall performance, but its competition is tough.
The graph below depicts the cooling fan's average noise over the PSU's operating range with an ambient temperature between 30 to 32 degrees Celsius (86 to 89.6 degrees Fahrenheit).
This is where the ION+ 860P excels, beating the rest of its competition.
The following graph shows the PSU's average efficiency throughout its operating range with an ambient temperature close to 30 degrees Celsius.
Fractal Design's overall efficiency is close enough to the category's average.
