Fractal Design Newton R3 1000W Power Supply Review

A Closer Look – Interior

For a 1000W 80 Plus Platinum unit I’d expect to see something made by Seasonic or Super Flower. However, in keeping with the recent trend of other power supply brands Fractal Design have thought outside the box and gone to a different OEM. With high-end and wattage 80 Plus Platinum units we have seen Cooler Master use Enhance, Corsair use Flextronics and Antec use Delta Electronics – all lesser well-known OEMs for the consumer power supply market. Fractal Design are bringing another fairly unknown OEM into play as they use ATNG Power. This platform has been analysed in depth by Jonny Guru and the conclusion is that it is actually of solid build quality and construction, despite its relatively unknown status.

Fractal Design provide the 135mm fan for the power supply so we expect it will be fairly quiet, the maximum RPM is around 1400.

The two primary side hold up capacitors are Nippon Chemi-Con made meaning they are Japanese capacitors. Both provide 270uF and are rated for 105 degrees celsius operation.

Moving down to the secondary side and….hang on a minute: 100% Japanese capacitors you say? I don’t think so. Teapo capacitors are still good, they have improved a lot in the past few years, but they still aren’t on the same level as Japanese capacitors. We might expect secondary side (3.3 and 5 volt) performance to be a little “average” because of this.

Here are a few more pictures of the rest of the internals. ATNG Power make extensive use of large heatsinks which helps to ensure the best cooling with the least amount of fan assistance.
