Fractal Design NEWTON R3 800 W
18 November 2013
Summary: The Newton R3 800 W model managed to register better performance than its bigger brother, the R3 1000W, mostly because of the significantly lower ripple I measured on the minor rails. The extra polymer caps that were used on the modular PCB apparently did the trick. The unit's overall performance was great, with tight voltage regulation on all rails, high efficiency, and the +12V's very good response to sudden transient loads.
Pros: Delivered full power at 46°C, Tight voltage regulation, Good ripple suppression, Efficient, Performance of +12V in Advanced Transient Response tests, Semi-fanless operation, Quiet fan under normal conditions, Stealth modular cables, 5 year warranty
Cons: High price, Low hold-up time, There could be less native cables
Summary: The fresh Newton R3 with 1 kW capacity is a very good performer, with the exception of high ripple on the minor rails. It managed to keep tight voltage regulation on all rails despite the tough conditions I used for all tests, and the efficiency levels it achieved were simply amazing. I think this platform has much potential, and the new Newton would gain a much higher placement, near the top of the corresponding performance graph, if ripple on the minors were lower.
Pros: Delivered full power at 45°C, Decent price/performance ratio, Highly efficient throughout all load range, Good enough ripple suppression at +12V, Tight voltage regulation, Semi-fanless operation, Quiet fan under normal conditions, Stealth modular cables, 5 year warranty
Cons: Ripple suppression on the minor rails, Low hold-up time, There could be less native cables
Summary: Final Thoughts
The Newton is the first power supply we have taken a look at from Fractal Design and I have to say I am very impressed. With the Newton Fractal Design wants you to know you are receiving a premium product and from unboxing to installation the power supply gives you that feeling.
When it comes down to performance the Newton R3 600W did great. Voltage regulation on both the 12V and 5V rails was under 1% and the 3.3v rail was just over 1%.
Pros: Good performance, Semi modular, 80PLUS Platinum certified, Attention to detail in packaging & design, 5 year warranty
