Usage & Testing
Spot checks of idle voltages put the 3.3V rail at 3.33V, the 5V rail at 5.02V, and the 12V rail at 12.02V.
For some stress testing, I used OCCT Perestroika on Windows XP 64-bit for 30 minutes of torture. For comparison, I include the results of the same test conducted with a Sigma SP-700 700W power supply.
The 3V rail was constant throughout the middle portion of the test, but returned to its idle voltage at the end. There’s definitely some stress on this line.
The 5V rail was very stable, rippling 0.60%. It spiked here and there, though.
The 12V rail was quite stable, rippling only 0.58%. It did have some spikes toward the beginning and end of the test, but the middle was constant.
Fortunately, none of these lines are overvolting. Hardware is much more resistant to overvolting than being starved by undervolting. Remember that most motherboards can handle a +-5% fluctuation in power, so these < 1% ripples are virtually meaningless when compared against each other. Changes in the power line or even background processes accessing hardware outside of the test could alter the results by that much.
The OCZ Fatal1ty 700W power supply unit is another excellent choice for a midrange gaming build. It provides solid power and isn’t going to waver when powering dual video cards.
However, the ~$140 cost of the unit is enormous compared to even OCZ’s own GameXStream line, which can be found for less than $100. However, if you simply must have Fatal1ty-brand equipment, then this power supply will not disappoint you. ThinkComputers gives the OCZ Fatal1ty Series 700W Power Supply an 8 out of 10 score.
– LED lit
– Fatal1ty logo is pretty sweet
– Lacks quick release connectors
– Not modular
