Silverstone Nightjar 450 (Continued)

Silent PSUs: Fortron Versus Silverstone

On the rear of the power supply there is an IEC socket and an non-illuminated main switch, as well as two LEDs that indicate the operational status of the power supply.

Whereas the top LED shows the temperatures—at over 55°C the usually green LED switches to yellow—the lower LED tells you whether the unit is in standby (orange), switched on (green) or cannot be switched on due to a fault (red). The latter occurs, for example, when the power supply has overheated and deactivated itself.

Unlike the Fortron Zen, the Silverstone unit is silent—even under the highest load—and does not make any whirring noises.

If the unit is placed under a load of 450 watts without ventilation, it switches itself off automatically after about two hours due to overheating, but at an output of 330 watts, we were able to operate it constantly. As with the Fortron unit, a very low flow of air is sufficient to enable constant operation even under a full load of 450 watts.

The Silverstone Nightjar was also able to operate our D201GLY2 board from Intel with no trouble at all.
