Fractal Design and one of their new ION series are one of the first power supplies we have reviewed. This is since we recently restarted PSU content. Today we have another new release in the SFX version of that same ION series. The Fractal ION + 850 we looked at previously impressed quite a bit, taking a draw of over 1000W from the wall and handling it under an extended duration workload on our real-world testbench. Now today we see if Fractal knocked out another good one or just another PSU.

SFX form factor PSUs are for the smaller form factor rigs. These include such cases as the TU150 we looked at before, the Streacom DA2, and things such as the Dan Case models. Fractal, of course, has its own SFX compatible chassis such as the Node 202 and others. These are made for those who live the SFF life or small form factor/slimline rigs. Being Gold rated at 650W, I have to assume that at the least, this can support a quite high-end platform with a beefy GPU or even pair of GPUs depending on the enclosures capabilities.

The key features Fractal lists for the new ION SFX 650G are as follows:

  • Fractal Design UltraFlex DC wires have game-changing flexibility for effortless cable routing and connectors that twist and bend to fit your installation
  • Large 120 mm fan with true long-life FDB bearings
  • 80 PLUS® Gold Efficiency
  • Semi-passive Zero RPM mode allows for absolute silence in low load situations
  • Outstanding output quality with tight voltage regulation and extremely low noise and ripple
  • Fully modular design for reduced clutter and maximum ease of installation
  • Ultra-high strand count 0.08T wire gives cables fluid flexibility while maintaining a high current capacity
  • Specially formulated 80P PVC insulation offers just the right amount of rigidity for easy cable management
  • Premium Japanese 105°C capacitors provide enhanced reliability and durability
  • Full electrical protection suite includes Over Power Protection, Over Voltage Protection, Short Circuit Protection, Under Voltage Protection, Over Current Protection and Over Temperature Protection
  • Includes SFX-to-ATX mounting bracket
  • Extensive 10 year warranty

This is quite a robust feature set. Although I do need to mention that while a 10-year warranty is excellent, it is not necessarily a stand-out feature at this point. Many manufacturers now offer 10-year warranties on their PSU models. However, one feature I do want to call out is something I observed on the last ION series PSU. That is the flexibility of the PSU cables; they do bend quite smoothly and quickly, which is a significant plus. This is especially true with short wires and super-tight spaces typically associated with an SFF build. Also, the ability to shoehorn a full 120mm fan into an SFX supply is quite the feat and should mean quite a capable cooling for the small unit.

The PSU is, of course, labeled the ION SFX 650G, and the part number for this specific unit is FD-PSU-ION-SFX-650G-BK, which signifies the 650W model of the ION series in SFX form factor. The one thing is the color designation, which I did not see any mention of another color. I assume that all fractal parts have a color designation even if only offered in a single color. Being SFX/SFX-L, the ION SFX 650G measures at 125mm length, 125mm Width, and a height of 63.5mm.

The MSRP from Fractal for the ION SFX 650G is $109.99, and this is quite good. The SFX market is far less flooded than standard ATX supplies. Current pricing shows SFX units at places like NewEgg checking in at the 550W range for the same price. Whereas competing gold-rated SFX units in the 650 range can run between 10-20 dollars more expensive. This gives the ION a distinct advantage, as long as it survives our real-world stress and durability testing.
