The performance is high, but the difference from the RM850x is noticeable.
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 very low. We would be highly impressed if there wasn't the RM750x, which is one of the quietest 750W units that money can buy today.
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 level is satisfactory, and higher than what the RM750x achieves.
