Fractal Design Edison M Series 750W Power Supply Review

Quality Construction And Good Performance

In our opinion, Fractal Design made the right decision to team up with Seasonic to build its Edison M PSUs. Seasonic enjoys a good reputation and has lots of experience in this field. The Edison series offers reliability and high performance in the mainstream and mid-capacity PSU segment, which are of high interest to most users. The Edison M 750W PSU we evaluated today performed well overall, and if it didn’t have a sudden increase in ripple at 5V during higher loads, it could have easily achieved a better performance score. In addition, we would have liked to see lower inrush current readings and a bit higher efficiency levels. This is definitely an affordable Seasonic platform, designed to keep costs down and not offer high-end performance. However, we had to compare it with more advanced products, and the competition in this market segment is tough.

This product's high price is its Achilles’ heel. Priced more aggressively, it could be considered a good deal, but at the time of this review, it's not. Fractal Design should reconsider what it's charging for the Edison M 750W, especially if the company wants it to do well in the U.S. market. Moreover, under normal conditions and under light loads, the PSU is quiet enough. However, when it's overworked, the fan can be really noisy, which won’t make most users happy. So, if you don’t want noisy system components and your system can apply high stress to a PSU with 750W capacity, then I suggest you look elsewhere.

Although Seasonic and Fractal Design do use a good-quality FDB fan in this unit, the fan has a smaller diameter than the typical 140mm fans found in most PSUs today. Therefore, to remove the heat from the PSU’s internals, it rotates at increased speeds, thus producing more noise. The truth is that smaller-diameter fans can offer more focused airflow than larger ones. However, we believe that in high-efficiency units like this one, a larger fan could do the job equally well, at the same time significantly lowering the output noise under full load conditions.
