Testing results (Efficiency, Noise & Thermal)
The AX760i is an 80Plus Platinum certified power supply so we did expect a very high electrical efficiency. During our testing and at 50% load, the AX760i managed to reach 93.6% efficiency when powered by a 230V source and 92.8% efficiency when powered by an 110V source. The efficiency appears to be more stable when the unit is powered by a 230V source, holding at 92.4% and above across the entire load range. When powered by an 110V source, the efficiency drops at heavy loads but never goes below 91%.
Our noise level readings up to 30% load were lower than 20dB(A) and essentially superficial, since the fan of the AX760i starts only when the load is higher than about 35%. The pre-programmed fan profile is obviously optimized for quiet operation as the fan will spin very slowly, maintaining very low noise levels up to 80% load. Only at heavy loads will the fan spin fast enough to reach clearly audible levels from 3ft away.
As the fan of the AX760i does not spin at 20% load, the temperature reading at that point was essentially that of the ambient air at the front side of the power supply. Even when the fan does start, the temperature delta is very low albeit the fact that the fan speed is very slow. Apparently the very high efficiency of the AX760i does the trick and the power supply remains very cool without the need of strong active cooling.
