Specifications and Part Analysis
The Fractal Design ION+ 860P achieves excellent overall performance and quiet operation, even under high ambient temperatures and increased loads. The competition in this category includes strong opponents like the Seasonic SSR-850PX, FSP HPT850M, and Corsair HX850. But Fractal Design's offering hits an attractive price point, and it's quieter than the other PSUs in our comparison, too.
The last time we reviewed a Fractal Design PSU was in 2015, so it was a pleasant surprise to see the company revitalizing its power supply portfolio with new products. The ION+ series includes four models with capacities ranging from 560W to 860W. They're all 80 PLUS Platinum-certified. The highest-end implementation also has ETA-A efficiency and LAMBDA-A+ noise badges from Cybenetics. All ION+ units are fully modular and use a capable High Power platform.

Cooling is handled by a 140mm fluid dynamic bearing fan. It features a semi-passive operating mode that can (thankfully) be deactivated. Fractal Design employs several tricks to reduce the noise level of its fans, including counter-balanced magnets and notched blade edges.

The cables are sufficiently long, and they include an adequate number of connectors. Fractal Design claims that its UltraFlex cables easily bend and twist to simplify installation in tight spaces. Indeed the cables are very flexible, although some of them use thicker wires to accommodate high amperage. The fact that there are no in-cable caps should also help during the routing and cable management processes. Our only complaint is that the main ATX cable isn't flat like the other ones.

We encountered this platform most recently in Thermaltake's 850W Toughpower Grand RGB Gold. Fractal Design asked for some modifications from High Power, so now it includes inrush current protection. That's an essential feature for any power supply.

On the primary side, a half-bridge topology is used, along with an LLC resonant converter. We find typical stuff on the secondary side: a pair of DC-DC converters for the minor rails and synchronous rectification for the +12V rail.

The filtering caps are of high quality. Ripple filtering is mostly handled by polymer caps, while a smaller number of electrolytic capacitors provide the capacitance necessary to handle transient loads.

The fluid dynamic bearing-based cooling fan bears Fractal Design's logo. It has a very low 3V start-up voltage.
