With a bit better ripple suppression on the minor rails, the overall performance would be even higher. 

Noise Rating

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).

It has low overall noise output, but is not even close to the levels that the Corsair RM850x and the similar-capacity Seasonic Focus Platinum, achieve. 

Efficiency Rating

The following graph shows the PSU's average efficiency throughout its operating range with an ambient temperature close to 30 degrees Celsius.

It comes in second place here, showing this platform's potential. 

Power Factor Rating

The following graph shows the PSU's average power factor reading throughout its operating range with an ambient temperature close to 30 degrees Celsius.

    I know they're not actually made by Thermaltake, but I've had a Toughpower 650-watt for 7 years and had no issues whatsoever. They're good choices these days in a saturated market.

    I bought two of these power supplies to use in my new rig. BOTH of them had a high pitched whine when my computer was off or sleeping (MSI MEG x570 Unify). As much as I appreciated the long warranty and build quality, I prefer not to have a dog whistle in my PC case. They were returned.
