EVGA Supernova 750 G3 Gold Power Supply Review

Efficiency, PFC and Voltage Regulation

Voltage Regulation

For this test, the EVGA Supernova 750 G3 gave some astounding results. While there is a slight deviance from what the true base figures should be, we’d ask you to to take a close look at the numbers throughout the different load tests. As you can see, the voltages are amazingly consistent. Across nearly all of the results the specific difference between the results produced was exceptionally minimum and in 2 instances the results were completely consistent.

It is nothing short of remarkable that such a solid level of output is achieved. Particularly across the different levels of load we tested this at.

Power Efficiency

With the EVGA Supernova 750 G3 being a gold rated power supply, it is required to meet very high-efficiency ratings. As the chart below clearly shows, it does this with a very strong and comfortable margin. Across the entire range of testing, it teeters very closely to platinum levels of results with an efficiency never dropping below 90%.

Above that, the results themselves are also very consistent. Usually, you can see quite a big drop at the lowest and highest end and in this case, it’s quite minimal. This is clearly a very well designed power supply to give such good results.

Power Factor Correction

While the initial PFC rating is a little lower than we would have expected, the harder this power supply works, the better it gets. Generally speaking, that is consistent with most power supplies. With this tipping over 0.95 at 100% load though is, as per the results so far, another testament to the design EVGA has implemented here.
