Fractal Design Integra R2 750W Power Supply Review

Installation & Testing
Installing the Integra R2 is very easy. It has a small compact size, so it should be easy enough to fit in pretty much any case. We had no issues getting it installed in our Cooler Master Cosmos II case. With such a large case it was easy to hide extra cables too since the unit is not modular.

One thing I did notice was that the SATA cables were sort of upside down, you can see what I mean from the photo below.

We will be testing the Triathlor FC 550W in our Intel X79 system, which is comprised of the following components.

Processor: Intel Core i7-3820
Motherboard: ASUS P9X79 Pro
Video Card: Radeon HD 6950
Memory: 16GB Kingston 10th Anniversary
Power: Fractal Design Integra R2 750W
Storage: 750 GB 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 3.30V, 5V and 12.1V respectively. We will be running OCCT’s power supply test for 1 hour to stress test the power supply. Below are the results.

2013-06-29-17h54-Voltage-+3.3 V

2013-06-29-17h54-Voltage-+5 V

2013-06-29-17h54-Voltage-+12 V

While the 5V rail was very solid both the 3.3V and 12V rails did show a lot of “ripple”. Even so all rails stayed within the 5% voltage regulation that we like to see, actually all rails were under 2%, which is really good.
