Antec High Current Gamer 620W
To test power supplies, we believe that creating real-world circumstances and conditions are important to consumers who need to relate to what they would use and experience in a computer system setup. Consequently, our methodology is fairly straightforward, as we assemble power-hungry components that will push a unit to its full capacity. We monitor the results at various loads using a digital multimeter for voltage regulation, and an oscilloscope for ripple measurements.
When examining the voltage regulation results we are looking for the voltage output and any fluctuations that might occur. The current ATX specifications allow for the following fluctuations in voltage outputs, and these represent a 3% variance:
- 3.3V Rail: 3.135V – 3.465V allowable
- 5V Rail: 4.75V – 5.25V allowable
- 12V Rail: 11.4V – 12.6V allowable
Below are the voltage regulation results:
When we look at the voltage regulation results, the High Current Gamer 620W does very well, even when fully loaded. There was minimal movement on the rails, and all results are well within specification.
When examining the ripple, or noise, the ATX specifications allow for 50 mV peak-to-peak variations for 3.3V and 5V, and 120 mV p-p for the 12V.
We measured the results at just below full load, and the results are as follows:
Ripple results are good, nothing out of spec, and sit very much middle of the road from what we’ve seen in other units. The High Current Gamer isn’t a standout, but it gets the job done quite well.
