Delivery and Specifications

As noted earlier, the Fractal Design Integra R2 750W is a non-modular PSU, which means that all the cables are permanently attached to the PSU, which makes the life a bit harder if you are looking to make a clean PC setup.

Cables
Cable	Length
1 x ATX 20+4 pin	52 cm
1 x EPS/ATX 12V (4+4) pin	66 cm
2x PCI-E 6+2 + 6+2 pin	52, 59 cm
1 x 3x SATA	56, 70, 84 cm
1 x 3x SATA	36, 50, 64 cm
1 x 2x Molex + 1x Floppy	55, 68, 71 cm

The connectivity is pretty decent for a 750W PSU as it packs enough power and connectors for multi-GPU configuration, featuring a total of four PCI-Express 6+2-pin power connectors as well as a bunch of others for peripherals, including a total of six SATA, two Molex and single 4-pin Floppy connector. Although most peripheral and accessory devices tend to rely on SATA power connectors these days, we would really like to see a bit more Molex connectors on Fractal Design R2 750W. The cables are 18 AWG. High end PSUs normaly use better 16AWG or even better.

Specifications
Voltage	Current	Power
+ 3.3 V	25 A	150 Watt	750 Watt (Total)
+ 5.0 V	20 A	150 Watt
+ 12 V	56 A	672 Watt
- 12 V	0.3 A	3.6 Watt
+ 5 Vsb	3.0 A	15 Watt

The Fractal Integra 750 does not use a single +12V rail design but a two rail design. It should be taken into an account that it actually provides 55Amps on both rails combined. When there is load on only one rail the Integra 750W is capable of delivering 30Amps on 12V1 and 30Amps on 12V2. Most PSU makers are currently going back to the single +12V rail design, but this design also does not represent a big problem unless you are pushing for extreme multi-GPU setups that require much higher-end PSUs.

The Integra R2 750W has been 80Plus Bronze certified. This means, that the efficiency of this PSU should be above 82% at 20% load, above 85% at 50% load and above 82% at 100% load.

As you can see from the list below, the rest of the features include standard protections and a 3-year warranty which is pretty much what you get with a mid-range class PSU.

Dimensions (W x H x D): 150 mm x 86 mm x 140 mm
