The following table lists the industry wide specifications for DC Output Voltage Regulation.
| Output | Range | MIN | Normal | MAX | Unit |
| +12V1DC | ±5% | +11.40 | +12.00 | +12.60 | Volts |
| +12V2DC | ±5% | +11.40 | +12.00 | +12.60 | Volts |
| +5VDC | ±5% | +4.75 | +5.00 | +5.25 | Volts |
| +3.3VDC | ±5% | +3.14 | +3.30 | +3.47 | Volts |
| -12VDC | ±10% | -10.80 | -12.00 | -13.20 | Volts |
| +5VSB | ±5% | +4.75 | +5.00 | +5.25 | Volts |
We used the Speedfan utility in order to check the voltages for our system with the Rocketeer installed. We took two measurements, one in idle and one more while running the 3DMark2005 benchmark. In the latter case, we also set the rotation speed of our seven fans (2x120mm, 2x80mm and 3x40mm) to maximum for more power consumption. Our system also has a 7800GTX VGA card, three hard disk drives and two DVD burners.

In almost all cases, the voltages were within the industry set standards. For the +3.3V rail however, the Speedfan utility reported +3.47V for most of the time, but there was the odd spike hitting +3.49V. The limits for this rail are +3.14V to +3.47V. We believe that with an even higher load, there may be further drift from the nominal voltage. Otherwise, a very good performance from the Rocketeer 600W.
Ambient noise, mostly emanating from the fans rotating, is another very important factor when evaluating a PSU. In this regard, the Rocketeer performed according to the manufacturer's specifications, and it is indeed quiet. However, if you decide to flip the Turbo fan switch on, make sure you really need to :-). This activates the 120mm fan and the noise from both fans working at maximum rotation speed is high and bothersome, even when playing a game with the volume turned up. The noise is noticeable, no matter what you do.
