Performance, Noise and Efficiency
Performance Rating
The SF600 Platinum manages to keep its throne, despite its lower power density. Apparently 750 watts is too much for such a small platform and you cannot have both top performance in all areas and such high power output.
Noise Rating
The graph below depicts the cooling fan's average noise over the PSU's operating range, with an ambient temperature between 30°C and 32°C (86°F to 89.6°F).
The SF750 features a quiet overall operation, but as expected the SF600 Platinum is even quieter.
Efficiency Rating
The following graph shows the PSU's average efficiency throughout its operating range with an ambient temperature close to 30°C.
Again the fight is between the two top-notch Corsair SFX units, with the lower capacity one winning the race.
