Fractal Design Newton R3 600W Power Supply Review

Installation & Testing
Installation of a power supply is pretty much straight forward.  We are installing the Newton R3 600W in our Cooler Master Cosmos II case so we had quite a lot of room to work with.  I did not have any issues with installation and the flat cables routed very easily.

We will be testing the Newton R3 600W in our Intel X79 system, which is comprised of the following components.

Processor: Intel Core i7-3820
Motherboard: ASUS P9X79 Pro
Video Card: EVGA GeForce GTX 680
Memory: 16GB G.Skill RipjawsZ
Power: Fractal Design Newton R3 600W
Storage: 750GB SATA II Drive
Cooling: Noctua NH-L12
Case: Cooler Master Cosmos II with 5 fans

We will be using OCCT to test this power supply.  Initial spot check on the 3.3V, 5V and 12V rails were 3.33V, 5.08V and 12.19V respectively.  We will be running OCCT’s power supply test for 30 minutes to stress test the power supply.  Below are the results.

3.3V

5V

12V

The 3.3V rail had the most “ripple” as you can see from the graph above, but both the 5V and 12V rails were pretty solid.  The deviation for the 3.3V, 5V and 12V rails are 1.5%, .78% and .73% respectively.  This is great as we like to see anywhere 5% and under.
