Fractal Design Telsa R2 650W Power Supply Review

Installation & Testing
Getting the Tesla R2 installed in your system is just like any other power supply.  Mount it and connect your cables and you are good to go.  I had no issues installing the Tesla R2 in the Cooler Master Cosmos II.

We will be testing the Tesla R2 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 Kingston 10th Anniversary
Power: Fractal Design Tesla R2 650W
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 3.34V, 5.04V and 12.1V respectively.  We will be running OCCT’s power supply test for 30 minutes to stress test the power supply.  Below are the results.




The 3.3V rail had the most “ripple” as you can see from the graph above.  The 5V rail seemed to be the most solid.  The deviation for the 3.3V, 5V and 12V rails are 1.01%, 1.008% and 1.0083% respectively.  This is great as we like to see anywhere 5% and under.
