Load 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 Antec EDGE 650W power supply, 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.

Antec EDGE 650W 80 PLUS Gold Power Supply Review 26 |

Let's start by taking a look at the voltages, to see how well this unit did during testing. Starting with the 12V1 rail, we see 2% regulation from start to finish, with a total drop of .17V. 12V2 shows slightly better results, still with 2% regulation, but only a .15V drop in voltage. The 5V rail managed to stay within 1% of specification, with a total drop of .05V from start to finish. Moving towards the 3.3V rail, we see that regulation was within 2% of specification, with a total voltage drop of .05V.

DC Output quality for the Antec EDGE 650W was excellent, and well within specifications. During Test One, we saw 15mV of noise on our scope at 15% load. When we increased the loads in Test Two, the ripple climbed to a 24mV at around 50% load. Increasing loads even further showed that the noise on the 12V rail climbed to 34mV at 6500W.

The Antec EDGE 650W is rated for 80 PLUS Gold efficiency. This means that the power supply must perform at 87% / 90% / 87% efficiency, at 20% / 50% / 100% loads respectively. As you can see, the Antec Edge 650W performs exactly as expected. If Antec could have squeezed a bit more out of it, we would be looking at a Platinum power supply instead.

Final Thoughts

Antec's introduction is a welcome addition to their product like. The company has many models for sale, but it did feel like they were lacking in the area of something for enthusiasts who aren't trying to go broke and go home at the same time. The timing couldn't be much better either as there will be a lot of individuals looking to upgrade with the new Intel X99 motherboards and processors that have just hit the market.

From a performance standpoint, the Antec EDGE is a great power supply. Voltage regulation is very much within specifications across the board. When you are staying within 2% regulation and your ripple is also quiet low, you know your power supply will continue to keep your system stable, as you load it down. It even does it all without skimping on the efficiency.

The noise level of the unit is rather impressive too. The rubber isolation mounts do exactly what they are meant to do in combination with the 135mm fan and keep the sound down really low. We were very happy with the results and know we could actually lower the sound a bit more if we removed the GPU and just went with integrated graphics, which is always a viable option, if you aren't going to be gaming.

All of this comes together to make a great power supply that fills the void needed in Antec's lineup. We gladly recommend this unit to anyone that is looking to build something as simple as a low-end office PC, all the way up to someone that is going to be gaming on a pair of relatively high-end video cards. It will do it with or without the flair since you can turn the lights off. The one thing that the Antec EDGE 650W power supply will always do is do it with silence and that's something that we will never argue with.
