Test Results


Our load tests utilize a couple of FAST ATE active load testers, and a variety of other equipment such as an oscilloscope, power conditioner, temperature probe, and a power consumption meter. You can read more about our standard testing approach here.


The tests performed are based around six conceivable setups that are out there, and progressively load down the PSU up to the power supply's limits, or 1000W; whichever comes first. Since our test equipment's limits are lower than that of the EVGA SuperNOVA G2 1600W power supply, we can test it to 1000W.




The above tests represent typical loads that we have measured from various systems, and are meant to give a rough idea of where your computer might fall in line with our tests. Please keep in mind that each system is different, and actual loads can vary greatly, even with similar hardware.




Let's start by taking a look at the voltages, to see how well this unit did during testing. Starting with the 12V rail, we see 1% regulation from start to finish, with a total drop of .03V. The 5V rail managed to stay within 1% of specification, with a total drop of .03V from start to finish. Moving towards the 3.3V rail, we see that regulation was within 1% of specification, with a total voltage drop of .02V.


DC Output quality for the EVGA SuperNOVA G2 1600W was excellent, and well within specifications. During Test One, we saw 6mV of noise on our scope at 14% load. When we increased the loads in Test Three, the ripple climbed to a mere 9mV at around 35% load. Increasing loads even further showed that the noise on the 12V rail climbed to 12mV at 1000W.


The EVGA SuperNOVA G2 1600W is rated for 80 PLUS Gold efficiency. This means that the power supply must perform at 87% / 89% / 87% efficiency, at 20% / 50% / 100% loads respectively. As you can see, the EVGA SuperNOVA G2 1600W performed exactly as would be expected to reach these levels of efficiency. There are no reasons to believe that this unit would not continue to perform as necessary through 1600W for 80 PLUS Gold certification.
