Specifications and Part Analysis
The Fractal Design Ion+ 660P achieves good performance and dead silent operation. Its low noise output under all conditions is among its significant advantages over the popular Seasonic Focus Plus Platinum. The latter performs better, but it has 25.35 dB(A) overall noise output, while the Ion+ 660P stays much lower at 13.74 dB(A). With a street price of $109.99 (£104.99 in the UK), the Ion+ 660P is about the same price as its main competitor and offers a quieter experience but a bit less performance.
We have already evaluated Fractal Design's 860W Ion+ model, which performed quite well and managed to keep its noise output low, even under harsh conditions (increased loads and operating temperatures). Next on our list is the 660 W model, which has enough capacity to power a strong single-GPU system. Like its big brother, the Ion+ 660P promises for good performance and dead silent operation. Lately, more and more users seek quiet components, and manufacturers have to comply if they want to remain in the game.

The cables are indeed highly flexible, as Fractal Design states and pretty long. Our only objection here is the small distance between the peripheral connectors, at 120mm. Normally it should be 150mm, at least, but most manufacturers try to restrict the cost by chopping down the distance between those connectors.
The 560W and 660W models come with a single EPS connector, while the other two members of the Ion+ line with 760W and 860W max power have a couple of these connectors.

This is a well-built platform, provided by High Power. The design is clean, without any wires blocking the airflow. Moreover, the clearance between the parts is enough for the air to move freely among them and help in heat dissipation.

On the secondary side, a pair of small heat sinks assist in cooling down the +12V FETs, which are installed on the solder side of the PCB.
A great number of polymer caps is installed on the modular side of the PCB. Several quality electrolytic caps, installed on the main PCB, also handle ripple filtering.

The soldering quality is pretty good.
The cooling fan measures 140mm across and uses a fluid dynamic bearing.

redgarl Sooo... anandtech is having the exact opposite conclusion and even calling it the best Stirfa PSU series... are you even knowing what you are doing?Reply
https://www.anandtech.com/show/14693/the-fractal-design-ion-760p-80plus-platinum-psu-review/5
Electrically, the Ion+ 760P positively surprised us. As soon as we noticed that it is a design originating from Sirfa (High Power), we believed that most of the electrical figures would end up being mediocre, as Sirfa usually designs products that are competitive in terms of value, not performance. The Ion+ 760P is an entirely different story, delivering outstanding power quality across the entire load range and under any operating conditions, easily competing toe-to-toe with any other top-tier unit that we've reviewed so far. Furthermore, not only it is very efficient under normal circumstances, but it's able to maintain its exceptional energy conversion efficiency figures even when the ambient temperature gets very high. -
Aris_Mp Yes, I know very well what I am doing and if you bother to read the review and the provided data, you will also get an idea.Reply -
Carabyte This PSU has very low EMI compared to other's I'm seeing on your site. Do you have a page with the EMI chart for every PSU? I'd like to know what's the lowest EMI PSU you have found at 650-750Watt range. Meaning overall the least peaks, smooth and lowest peak. This one looks quite good, is it one of the best?Reply
Thanks!
