Fractal Design Ion+ Platinum 660P PSU Review

There is no doubt the Fractal Design Ion+ Platinum 660P is a very high efficiency supply that delivers quality power at a very reasonable price point.

Fractal are using High Power as the OEM partner for this unit, and in reality, it’s a solid, technically proficient unit ideal for a wide range of systems.

First impressions are positive, the unit is well finished and the neutral colour scheme will ensure it will fit into themed system builds without standing out. If you are hiding it behind a PSU shroud, I guess it doesn’t matter either way.

Load regulation is very tight, and the 660P dealt with our cross loading test without a problem. Ripple suppression is another high point for this product, hitting a maximum of only 10-20mV from all rails under a full load situation. Thanks to the adoption of a quality Fluid Dynamic Bearing fan, noise levels never get too intrusive either, even under very high load situations. You could happily run this unit at 500w all day long without noticing fan noise.

Efficiency is impressive, with the unit hitting around 94% around 40-50% load. Ideally you want to be running between 300 and 450 watts to achieve the highest levels of efficiency from this supply – this is actually a sweet spot for the majority of gaming systems on the market today.

The modular cabling is one of the key talking points with this new range of Ion+ Platinum power supplies. The trademarked ‘UltraFlex DC cables’ are a very high strand count cable with specially formulated insulation to reduce the conductors to just 0.08mm in diameter. While we look at marketing ‘buzz’ words with a raised eyebrow, in reality, these cables are very soft and flexible, ensuring they are pleasant to use during a system build. You can bend and twist them to ease routing in tight spaces for instance, without fear of damage. I give them a resounding thumbs up.

The 660P model featured in this review will be available for $109.99/£104.99 in the coming weeks. At this price, it is hard not to recommend the 660P. While many people still think we all need a 1000 watt power supply for ‘peace of mind’ – the fact is that many gaming systems under full load will be taking between 300 and 400 watts at the wall- a high efficiency zone for this particular 660w unit.

KitGuru says: An extremely proficient Platinum rated supply – with enough power to cope with the majority of systems on the market today. At only £104.99 we feel it offers exceptional performance at a very competitive price point.
