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 higher than that of the Enermax Triathlor Eco 650W, we can test it to the maximum.





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 2% regulation from start to finish, with a total drop of .19V. The 5V rail managed to stay within 2% of specification, with a total drop of .10V from start to finish. Moving towards the 3.3V rail, we see that regulation was within 3% of specification, with a total voltage drop of .11V.


DC Output quality for the Enermax Triathlor Eco 650W was good and well within specifications. During Test One, we saw 18mV of noise on our scope around 35% load. When we increased the loads in Test Two, the ripple climbed to 26mV at around half load. Increasing loads even further showed that the noise on the 12V rail climbed to 49mV at 630W.


The Enermax Triathlor Eco 650W is rated for 80 PLUS Bronze efficiency. This means that the power supply must perform at 82% / 85% / 82% efficiency, at 20% / 50% / 100% loads respectively. As you can see, the Enermax Triathlor Eco 650W performed exactly as would be expected to reach these levels of efficiency.
