Why you can trust Tom's Hardware
The Ion SFX 500G achieves top performance.
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).
The overall noise output is lower than 30 dB(A), but the fan profile could be even more relaxed especially at higher loads.
The following graph shows the PSU's average efficiency throughout its operating range with an ambient temperature close to 30 degrees Celsius.
The overall efficiency is close to the competition, but the PSU hits last place in the corresponding graph.
