Installation
Installation of the Fatal1ty Series 750W went about as you’d expect for a modular power supply; everything snapped into place with relative speed. The modular plugs were properly placed and spaced for easy removal. I had to swap out cables a couple of times, and I never had to unplug any cables that were in the way to get at the one I wanted. The flattened cables were very stiff, and took some pre-bending to fit where I needed them to in some cases.

As you can see, the modular cabling kept things relatively clean, though I did have to find a spot to tuck the extra EPS12v cable away. One area where this power supply disappointed was in the length of the modular cables. I normally like to run the PCI-E power cables back behind the motherboard tray, and only bring them forward right next to the video card. I was unable to do so with this power supply, as the cables were simply too short. Around on the back-side, a similar problem obtained with the SATA power cables; I had to make use of a Molex->SATA Y-adapter to provide power to all four drives in the test rig.
As promised, the fan produces a bright red glow when turned on, courtesy of the LEDs embedded in the frame. I could find no way to turn this off short of flipping the main power switch.
Testing
Testing was performed on the following system:
| Test System | |
| CPU | Phenom II X6 1100T Black Edition @ 3.3GHz |
| Heatsink | Thermalright HR-02 |
| Motherboard | Jetway Hummer HA-09 |
| Chipset | AMD 890GX |
| Graphics card | Sparkle GeForce GTX 465 |
| RAM | 2x4GB SuperTalent DDR3-2000 @ 1600MT/s, CL9 |
| Sound | Creative Sound Blaster X-Fi Titanium HD |
| SSD | Crucial RealSSD 256GB SATA 6Gb/s |
| HDD 1 | Seagate 7200.10 500GB |
| HDD 2 | Western Digital Caviar Green 5400RPM 500GB |
| HDD 3 | Western Digital Caviar Green 5400RPM 1.5TB |
| Power Supply | OCZ 750W Fatal1ty Series |
| Case | Silverstone Fortress FT-02 |
| OS | Windows 7 Ultimate |
| Drivers | Catalyst 10.11, Forceware 258.96 |
Testing was performed with a standard multi-meter, with readings taken at the BIOS setup screen, idling on the Windows desktop, and under load with Stress Prime Orthos edition and FurMark running simultaneously. All voltages were averaged over a period of 10 minutes.
| Voltages | Boot | Idle | Load |
| 3.3V | 3.31 | 3.35 | 3.36 |
| 5V | 5.30 | 5.50 | 5.40 |
| 12V | 12.65 | 12.60 | 12.70 |
While voltages were a little bit on the high side, they remained fairly stable throughout. My readings never wandered more than 0.01v away from the listed averages during any of the 10 minute testing periods.
OCZ is a great company with high quality products. I’ve been using my DDR ram from OCZ and after two years it’s still running strong. It’s safe to assume thesepower distribution blocks would have efficient power distribution!
